TS-T&V-002-2008 乘用车辆动力总成简化耐久性试验 Passenger Vehicle Brief Powertrain Durability Test 1 适用范围 注:除非特殊说明,本规范不能替代任何现行的法律法规。 1.1 目的 通过加速动力总成输入,模拟客户的恶劣使用环境,提供一种简化的乘用车动力总成耐久性和可靠性评估方法。 1.2 前言 本试验流程由五个试验子规范组成。依据轿车选配件或试验目的不同,本试验还提供两个选择试验。本试验第4节所述,这些子规范组合起来可提供相当于一般客户160,000公里的较高强度动力总成输入。 本试验主要目的是提供一种在较短时期内(在此期间内可重复试验以发现动力总成系统的薄弱点)快速评估动力总成性能的方法。本试验尽量减小底盘结构输入,以避免由此可能引起的失效而延误本试验的完成。此外,本试验未明确低速、怠速、轻度倒车或类似城市行驶非剧烈换档等的操作,因为相对于高强度动力总成输入来说,这些操作的试验输入强度很小。 1.3 适用范围 本规范适用于乘用车和轻型卡车。 2 规范性引用文件 2.1 外部 标准 excel标准偏差excel标准偏差函数exl标准差函数国标检验抽样标准表免费下载红头文件格式标准下载 /规范 无 2.2 泛亚汽车技术中心标准/规范 · TS-R-M01 粗糙路试验规范 · TS-R-M30 城市试验规范 · TS-R-M33 直道试验规范 · TS-R-M34 高速试验规范 · TS-R-M13 高扭矩试验规范 · TS-R-M20 长途规范 起草人/日期: 批准/日期: Draftsman/Date: APP/Date: 发布日期(Release date): 实施日期(IMPL Date): 版本号(Version):001 两项可选试验是: 牵引力控制试验 腐蚀试验 2.2.1 由于本试验是一个简化试验规范,试验中减少甚至删除了一些强度较小的和费时的输入。除此之外,由于加速试验和试验场环境限制的原因,本试验并不囊括所有已知客户的实际使用情况。如果想进行更严格的试验以模拟某些特殊客户的使用情况,可以考虑在本试验 计划 项目进度计划表范例计划下载计划下载计划下载课程教学计划下载 中加入其他的试验流程。 下面给出了一些应予考虑的内容: · 拖车牵引试验 R-14L-1, R-15-31, R-15-115 · 热区适应性试验 TS-T&V-003 (5月-8月) · 寒区适应性试验 TS-T&V-004 (11月-1月) · 高海拔试验 R17-15-23, R7-15-45 · 低使用频次试验 R-15-69 · 热负荷试验 R-15-69 此外,本规范也未充分考虑下列情形,需要在开发过程中另外关注。 · 制动系统、发动机控制系统、变速箱、管路及密封件的热老化考核 · 酸雨、鸟粪、紫外线、灰尘等造成的化学腐蚀和老化 · 乘客区域、行李厢区域等处的座椅、内饰材料的抗磨损性 · 停车时候的马路沿冲击、刮擦和低速顶撞 · 非常规保养(车辆清洗,润滑等) · 不按里程,按时间保养 · 使用材质差的非原厂商推荐型号的润滑、保养油液。 · 车辆陷入冰雪地、泥沙以及深水中 · 正确和不正确的使用防滑链 · 附件操作(车窗、雨刮器、空调、加热器等) 2.2.2 表一为目前版本的车辆动力总成简化耐久性试验子规范清单,其中包括每一个子规范循环的次数。 2.3 附加参考 若希望进行更为全面的试验,应参考 R-15-101“乘用车全面耐久性试验”或TS-T&V-001 “乘用车有限常规耐久性试验”。 本试验规范来自对定远及海南试验场周围环境温度的研究,参考了大量涉及客户实际使用、车辆环境和耐久性试验的报告。 3 资源 3.1 场地 定远试验场,中国 海南试验场,中国 试验场地附近的符合试验规范说明的各种公共道路和设备 3.2 设备 在试验过程中采用耐久性试验行驶 记录 混凝土 养护记录下载土方回填监理旁站记录免费下载集备记录下载集备记录下载集备记录下载 仪,如果没有行驶记录仪,需要给试验员提供一个精确的车速显示仪,以保证试验规范的准确性,车速表的显示范围有以下要求:须能达到160Kph或者能达到试验车的最高时速,哪一低就选用哪一个。同时,也应该给试验员提供相应的加/减速度计。 3.3 试验车辆 本耐久性试验是为了评估在相同的环境中客户实际使用状态下的车辆性能,所以试验车辆应采用一种类似于将新车发送往零售客户的方式进行运输。在运输前试验车辆不得有任何特殊的调整和返修。 如果出于其它试验目的(比如零件或车辆的设计评估、设计认证等)而进行耐久性试验,则应采用与试验目的相对应的试验规范进行试验。 3.4 试验时间 时间进度:30天 试验时间:275.2小时 3.5 试验所需信息 无 3.6 人员/技能 为了能准确地执行试验规范,试验执行人员必须经过专业培训。 4 程序 4.1 车辆准备 4.1.1 试验负责人应该将最高车速提供给驾驶员作参考。如果车辆装备的是手动变速箱,试验负责人还应确定提供给驾驶员换档点的速度。 4.1.2 为了准确的记录试验车辆的状态,需测量并记录试验车辆的设置与调整情况。这些测量不能影响车辆调整和设置。 4.1.3 轻型卡车和小型货运厢式车所要求的试验载荷应由试验负责人确定。为了保证正确安装和使用,试验载荷的质量和加载位置应该在试验车辆到达试验场地前确定。应使用合适的固定方法和设备,将所有试验载荷可靠地紧固在试验车辆上。试验载荷的加载方式应详细记录在试验文件中。 4.1.4 出于任何其它目的(如:设计评估等)而进行本耐久性试验的车辆,应采用一种适合于相应试验目的方式进行。试验零部件的安装、调整、设置和其它相关的试验信息应详细记录在试验文件中。 4.2 试验 4.2.1 试验安排指导 为了让车辆能以线性的方式合理的模拟用户的实际使用,本试验流程分为五个阶段,并应遵循在2.2节中列出的试验子规范的次序进行操作。 4.2.1.1 试验车辆不进行磨合,除非有特殊要求或者用户手册推荐的90%以上的客户会接受的操作。本试验的目的是使车辆在比一般客户操作更严格的情况下执行规范,而去掉磨合里程会使车辆运行情况更为严格。 4.2.1.2 任何规范不允许连续执行超过三个循环。 4.2.1.3 安排试验车辆在整个试验中的进度是一项比较复杂的工作。建议在执行下一个阶段的试验之前,尽可能的完成前一个阶段试验进度。 4.2.1.4 在试验中,有些试验子规范的执行开始和结束地点与其他的子规范执行地点相隔较远时,驾驶员应该选择最方便和有效路线行使到指定地点开始试验,并在轻加速/轻减速的操作下,按指定车速行驶,从而以避免对试验车辆的耐久性能产生影响。 4.2.2 腐蚀试验安排指导 加速腐蚀试验是本试验的可选项。若需要腐蚀输入,每一个TS-T&V-002试验按照两年的腐蚀强度进行输入。 腐蚀试验的安排和有关腐蚀输入的顺序参考GMW8738 “试验场腐蚀试验规范”。 4.2.3 维护保养试验规范指导 试验车辆保养维修应基于用户手册推荐或尽可能接近客户实际保养维修。 4.2.3.1 工具 维修和保养试验车辆所用工具应和客户车辆在服务维修站所用工具类似。 4.2.3.2 修理 当试验车辆出现客户所能察觉的异常征兆并可能促使客户去诊断维修时,需要对试验车辆进行维修。在这个基础上,试验驾驶员应根据4.3节所述及时准确报告试验车辆情况。并且,试验驾驶员应像车主那样,从客户的角度去观察和评估车辆的表现,并对可能存在的故障进行初步判断。 当试验负责人认为进一步进行试验可能存在危险时,需要对试验车辆进行维修。应当对可能存在故障的零件或系统进行单独的测试,以评估失效产生的结果和影响,如失效模式、次级顺序。当发生上诉情况时,试验人员应进行充分的沟通和交流,并都应记录存档。 如在检查或维修故障过程中发现其他故障,则在对该故障进行维修前应仔细评估,并提前判定在客户遇到相同故障时是否进行维修。试验员应像客户那样在维修前提供故障背景信息。 试验车辆维修技师应对所执行的维修操作做详细的维修报告。与其它试验文档一样,这些试验车辆维修报告是整个试验过程的重要记录,并可用于对车辆的维护的便利性进行分析研究。 4.2.4 可选试验 在提交试验要求之前应考虑两项附加的可选试验。若车辆装有牵引力控制系统(TCS),应考虑相关试验的选项。若试验要求有腐蚀输入,则按照在4.2.2节描述的腐蚀试验进行操作。 4.3 驾驶员责任 4.3.1 驾驶员应该是第一个发现车辆异常的人。他在试验期间要观察车辆的运行情况(就像用户一样),一旦车辆发生故障或驾驶员察觉到异常现象,应书面报告负责人。驾驶员应该明白在试验过程中应该扮演客户的角色,须对车辆的潜在故障进行初步的检查,并能够对车况作精确、全面的记录。对试验负责人而言,驾驶员是一个重要的车辆性能信息反馈源,前者应主动地与后者进行交流。 4.3.2 驾驶员必须严格执行规范的要求。只有将车速、路况和正确的驾驶操作等因素有机的结合才能保证试验的准确性。 4.3.3. 鼓励驾驶员参与到试验开发过程中去,对试验流程提出改进意见。 5 GM信息 5.1法律需求 无 5.2 一般信息 5.2.1 本试验的结果很可能也出现在一些客户实际使用过程中,因为本试验规范包含了基于用户实际操作的车辆使用情况。试验中,试验车辆的操作和使用环境应尽可能的接近随机选取的客户车辆的实际情况。本试验旨在将车辆置于比普通客户更为恶劣的使用条件下进行试验。 5.2.2 试验规范开发小组会继续监测样本用户的车辆操作情况,以获得能让耐久性试验更接近实际用户使用的数据。随着数据的收集和分析,试验规范会定时的更新。 5.2.3 本试验规范是用于取代GMUTES R1-15-6(自动变速箱耐久行试验)。 6 数据 6.1 计算 6.2 结果阐述 为了准确的记录试验车辆的状态,需测量并记录试验车辆的设置与调整情况。这些测量不能影响车辆调整和设置。 6.3 试验文件 在试验中与试验有关的任何因素都应被生成文字和图片文件,并保存。这包括车辆、人员、设备的标识、时间、天气、事故及故障信息、参与试验的相关人员的检查和评测,以及试验人员认为合适的其它信息。 7 安全 使用这个流程可能会涉及到具有危险性的材料、操作和设备。但本流程不能明确定义在规范使用中的所有相关的安全问 快递公司问题件快递公司问题件货款处理关于圆的周长面积重点题型关于解方程组的题及答案关于南海问题 。使用者在使用规范前须建立合适的健康安全使用指导。 8 发布和修订本 8.1 发布 参考GMUTS R-15-104-90规范 9 附录 表格 关于规范使用各类表格的通知入职表格免费下载关于主播时间做一个表格详细英语字母大小写表格下载简历表格模板下载 1 –试验基本构成信息 1 Scope Note: Nothing in the specification supersedes applicable laws and regulations unless specific exemption has been obtained. 1.1 Purpose To provide a brief durability and reliability performance evaluation of a passenger vehicle related to accelerated powertrain inputs representing a severe customer environment. 1.2 Foreword This Durability Test Specification is composed of five of the Durability Test Schedules. Two additional options are available depending on vehicle options or test intent. These test schedules when combined a described in Section 4 are intended to provide primarily high level powertrain inputs which are representative of 160,000 kilometers operation of a greater than average severity customer. The primary intent of this test is to provide an accelerated assessment of powertrain performance in a brief period of time (which allows for running repetitions of the test to discover system weak points). This test minimizes chassis structural inputs to reduce potential failures which could slow the completion of the test. In addition, this test does not address low speed, idle, light reverse, or city type light shift operations which in general are viewed as less damaging than higher level powertrain inputs. 1.3 Applicability This specification is applicable to passenger vehicles and light duty trucks. 2 References 2.1 External Standards/Specifications None 2.2 PATAC Standards/Specifications · TS-R-M01 Rough Road · TS-R-M30 City · TS-R-M33 Straightaway Performance · TS-R-M34 High Speed · TS-R-M13 High Torque · TS-R-M20 Extended Trip The two additional options are: Traction Control Option Corrosion Option 2.2.1 Due to the abbreviated nature of this test procedure, the less damaging and often damaging and often time-consuming inputs are greatly reduced or eliminated. In addition, this test does not encompass all known customer usage treatments. Some limitations are due to acceleration of time, and some are due to the constraints of the environment at the Proving Ground. If more rigorous exposure to these unique customer usage treatments is desired, other specialized testing should be considered as part of the vehicle test plan. Some considerations should be given to the following: · Trailer Towing R-14L-1, R-15-31, R-15-115 · Hot Weather Exposure TS-T&V-003(May-Aug., Hot Season) · Cold Weather Exposure TS-T&V-004 (Nov.-Jan., Cold Season) · High Altitude Operation R17-15-23, R7-15-45 · Low Usage Operation R-15-69 · Thermal Cycling R-15-69 (engine focused) Other aspects of vehicle usage which are not sufficiently addressed in this test and should also be considered during the development process include: · Appropriate temperature aging (thermal cycling) of components – brakes, engine controls, transmission, hoses, seals, etc. · Chemical degradation – aging, acid rain, bird droppings, ultraviolet radiation, dust exposure, etc. · Seat and seat restraint usage – normal wear and tear of interior passenger and cargo areas (other than driver position). · Curb impacts, scuffing, or pushaways (primarily parking related). · Non-maintenance of vehicle (lubricants, cleaning, etc). · Maintenance based on time periods (as opposed to mileage) · Non-specified fluids and lubricants (lower grade materials). · Vehicle stuck in snow, ice, sand, mud, or deep water. · Tire chain operation (proper and improper). · Accessory operations (windows, wipers, air conditioning, heater, etc.) 2.2.2 Table I provides a listing of the current version of Durability Test Schedules and specifies the number of schedule cycles per test. 2.3 Additional References. If a more comprehensive test is desired, R-15-101, “Passenger Vehicle Major Durability Test,” or TS-T&V-001, “Passenger Vehicle Limited Durability Test,” should be considered. The TS-T&V-002 test procedure has been derived from the Ding Yuan and Hainan Proving Ground Ambient Temperature Study and from a number of reports relating to customer usage, vehicle environments, and durability testing. 3 Resources 3.1 Test Facility. Ding Yuan Proving Ground, China. Hai Nan Proving Ground, China. And various public roads and facilities as specified in the driving modules near the testing facilities. 3.2 Test Equipment. These Durability Test Schedules are intended to be performed utilizing a Durability Test Drivers Aid. If the Drivers Aid is not available, some method of accurate speed indication up the 160 Kph or to the maximum speed the vehicle can reach, whichever is lower, should be provided to the driver for the accurate execution of the driving schedules. Also, some type of acceleration/deceleration rate indicator should be provided to the driver for the accurate execution of the driving schedules. 3.3 Test Vehicle Vehicles operated on this durability test for estimating their performance in customer use should be acquired in a manner similar to new car delivery to a retail customer. The vehicle should not be subjected to any special adjustments or treatments prior to delivery, especially in aspects which deviate from production intent. Vehicles operated on this durability test for any other purposes (e.g., design evaluation, design validation, etc.) should be acquired in a manner appropriate to that particular test intent. 3.4 Test Time Test time: 30 days Test hours: 275.2 hours 3.5 Test Required Information 3.6 Personnel/Skills. The procedures which comprise this test are intended to be performed by personnel specifically trained in the proper execution of the TS-T&V-002 4 Procedure 4.1 Vehicle Preparation 4.1.1 Maximum vehicle speeds are to be supplied by test responsible personnel for driver reference. If the vehicle is equipped with a manual transmission, the shift point speeds should also be determined and provided. 4.1.2 Measurement of adjustments and settings may be made as deemed necessary to document the condition of the vehicle. These measurements must be made without significantly affecting the adjustment or setting being considered. The intent of these measurements is to document the condition of the vehicle without changing the state of original assembly. 4.1.3 Light duty trucks and cargo vans requiring ballast must be identified to the test coordinator. Mass and location of ballast shall be determined in advance of vehicle arriving at facility to ensure ballast availability and correct installation. All ballast added shall be securely fastened to the vehicle using appropriate and acceptable cargo restraint methods and devices. Particulars regarding ballast shall be recorded. 4.1.4 Vehicles being operated on this test for any other purposes (e.g., design evaluation, etc.) should be prepared in a manner appropriate to that particular test intent. Details of test component installation, adjustments, settings, and other pertinent information are to be recorded. 4.2 Test 4.2.1 Test Scheduling Guidelines. In order to subject the vehicle to a reasonable simulation of customer usage in a linear manner of operation, the application of the driving schedules of this test is designated within five phases. Each schedule listed in Paragraph 2.2 describes a detailed sequence of operation to be followed. 4.2.1.1 The vehicle should not receive any “break-in” kilometers unless such are specifically required or specifically recommended in the Owner’s Manual in such terms that more than 90% of the vehicle purchasers or users would be expected to follow the recommendation. The intention of this Durability Test is to subject the vehicle to more severe than average operation and it is believed that the omission of “break-in” kilometers is more severe than is their inclusion. 4.2.1.2 Do not run more than three consecutive cycles of any schedule. 4.2.1.3 It is recognized that the scheduling of a vehicle on a test of this scope is complex. It is recommended that every effort be made to complete one phase before proceeding to the next. 4.2.1.4 In the event that some test schedules are specified which start and end at a location which is not near the Durability Loop Schedule, or any other test schedule which is already specified, it is intended that the driver proceed to the starting point by taking the most convenient and efficient route. All miscellaneous mileage should be driven at posted speeds and consist of light accelerations/decelerations, minimizing any conflicts with existing durability traffic. 4.2.2 Corrosion Scheduling Guidelines. Accelerated corrosion inputs are optional to provide the user with additional flexibility. Two years of corrosion is typically completed when corrosion inputs are desired with R-15-104. Refer to GMW8738” Proving Ground Corrosion Road Test Specification”, for scheduling guidelines and the proper sequence regarding corrosion inputs. 4.2.3 Maintenance Scheduling Guidelines. Test vehicle maintenance/repair will be based on Owner’s Manual recommendations and, as closely as possible, customer maintenance/repair practices, and shall be performed in a manner appropriate to the test objectives. 4.2.3.1 Tools. The vehicle is to be repaired and maintained with tools similar to those which would be used by a service facility working on the customer’s vehicle. 4.2.3.2 Repair. Repair shall be performed when the test vehicle displays symptoms which would be detected by the customer and which would be likely to prompt him to take the vehicle in for diagnosis and repair. On this base, it is the test driver’s role, as described in Section 4.3 to report that the vehicle requires attention. The driver should, in essence, be “the customer,” viewing and evaluating the vehicle’s behavior as would the owner, and recommending checkout of possible malfunction. Repair may also be performed when, in the opinion of the responsible test user, further operation of the vehicle would prove hazardous to test personnel. In that case, a separate test involving the part or system in question is to be conducted under controlled conditions to determine all effects and results of the malfunctions such as failure mode, second and third order failures. It is essential that the communication loop be closed in cases of this nature. Any communication or information resulting from such a test is to be carefully documented and preserved. In the event that an additional malfunction is discovered during the inspection or repair of another item, it is to be evaluated carefully before any corrections are made. Consideration should be given to the probability that the customer’s mechanic would have discovered the malfunction, informed the customer, and received the authorization for repair. The test user should use supporting information defining customer practice in repairing such items. The individual performing the repair should prepare a report documenting the operation. These reports, as well as other findings, are a major result of the overall test process and should be recorded and analyzed as data relating to test vehicle repairability and serviceability. 4.2.4 Optional Durability Test Schedules. The two additional options should be considered prior to submitting a test request. If the vehicle is equipped with a Traction Control System (TCS), the related test option should be considered. A series of corrosion schedules are available and described in Section 4.2.2 if corrosion inputs are required as part of the test. 4.3 Driver Responsibility. 4.3.1 The driver is to provide the first indication that the vehicle requires attention. During the execution of the test, the driver is to observe vehicle behavior (as would a customer), and is to inform the responsible individuals through written comment whenever a malfunction occurs or unusual behavior is experienced. The driver should, in essence, play the role of ‘the customer’ and should initiate checkout for potential repair of the vehicle. The driver should be informed of this responsibility and should be instructed to keep accurate thorough records on the vehicle. The driver is an important source of vehicle performance information for the test coordinator, with whom he or she should actively communicate. 4.3.2 The proper execution of this durability test is highly dependent on close driver adherence to the schedules and the instructions contained therein. This is because accurate correlation with field experience can only be achieved by means of tailored combinations of vehicle speed, road surface and driving maneuvers. 4.3.3 Driver participation in test development, by observing and commenting on any aspects of the test procedure which could be improved, is encouraged. 5 GM INFORMATION 5.1 Legal Requirements. NONE 5.2 General Information. 5.2.1 Results of this test should be regard as highly probable to also occur in the hands of some customers inasmuch as the schedule contains vehicle treatments based on measured customer vehicle operation. The durability test contains vehicle operational and environmental exposure designed to match data collected on groups of randomly selected customers’ vehicles. The intent of the test is to subject the vehicle to the treatment of a greater than average severity customer for each measurable environment. 5.2.2 CPE is continuing to monitor the operation of randomly selected customers’ vehicles, to obtain data that will better enable this durability test to represent actual customer usage. This test has been and will continue to be updated periodically as new field data is obtained and analyzed. 5.2.3 This test specification is intended to supersede the R1-15-6, “Automatic Transmission Durability Test.” 6 Data 6.1 Calculations 6.2 Interpretation of Results Measurement of adjustments and settings may be made as deemed necessary to document the condition of the vehicle. These measurements must be made without significantly affecting the adjustment or setting being considered. 6.3 Test Documentation Written and photographic documentation is to be generated and maintained on all factors involved in the test. These include vehicle, personnel, and equipment identifications; time, climate, incidents, or malfunctions; comments or observations from any involved personnel; and other factors that the test user deems appropriate. 7 Safety This procedure may involve hazardous materials, operations, and equipment. This method does not propose to address all the safety problems associated with its use. It is the responsibility of the user of the method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 8 Release and Revisions 8.1 Release Refer to GMUTS R-15-104-90. 9 Appendix Table 1 Base Test Information 6 of 18 1 of 18 17 of 18 16 of 18 15 of 18 14 of 18 13 of 18 12 of 18 11 of 18 10 of 18 9 of 18 7 of 18 5 of 18 4 of 18 3 of 18 2 of 18 PAGE
