时速120km/h的提速货车可靠性试验与研究
|
摘要
鉴于2006年初,在提速货车120km/h环行线第二阶段可靠性试验中,发现初始动力学测试的38辆车中有10辆提速改造空车部分动力学性能指标超标;在近两个月运行试验的60辆车中有5辆60t级车(G60K型罐车2辆,NX17BK型平车1辆,C64H型敞车1辆、G70H型罐车1辆)承载鞍磨耗严重;摆动式转向架导框摇动座固定块脱落和侧架向内倾斜等问题。
为尽快解决可靠性试验中出现的问题,在2006年10月1日前完成第六次大提速的各项准备工作,确保第六次大提速顺利进行和提速货车120km/h运行安全可靠,铁道部运输局装备部货车处立即组织齐车公司,西安、北京二七、株洲和眉山等有关工厂和铁科院、四方所的技术负责人和专家集中在环行线进行专题攻关,并于4月20日成立了提速货车120km/h可靠性试验联合工作组,系统分析、全面查找环行线可靠性试验中出现问题的原因,研究提出改进措施和确保120km/h提速安全运行的技术方案、实施方案、运用检修限度及评价标准。
针对上述车辆在试验中出现的问题,我迅速开展工作,首先对所有的60辆参试车辆进行了全面外观检查,对出现问题的7辆典型车辆进行了全面分解检测及1辆状态良好车辆的对比分解检测;对前期多次动力学试验、综合性能试验及全面分解检测等数据进行了梳理、汇总及分析;同时运用静力分析及动力学仿真计算比较分析的方法进行多角度分析,查找影响因素,讨论阶段分析结果和改进方案,研究安排主要工作。在充分分析、计算和讨论的基础上,提出了改进措施和试验验证方案并组织进行了动力学试验验证。
In the light of early 2006, in the truck speed 120km / h circular line in the second phase of the reliability of the test and found that the initial dynamics of the 38 cars tested in the 10 empty part of the transformation of speed dynamics performance standard; in the last two months Test run of 60 cars in 5 60t-class cars (G60K-2 tankers, NX17BK-a-car, C64H-a gondola car, G70H tanker-a) a serious bearing wear saddle; swing-guided bogie frame Block shake off a fixed block and side of the plane tilted inward.
As soon as possible to test the reliability problems,in October 1, 2006 to complete the sixth major acceleration of the preparatory work to ensure that the sixth great speed and smooth vehicle speed 120km / h safe and reliable operation, Transport equipment, the Ministry of Railways Board lorries Department immediately Qi car company, Xian, Beijing on February 7, Zhuzhou and Meishan Iron and factories and so on ASTRI, the Quartet is responsible for the technical and expert on the Central line for research topics, and 4 20 to set up a truck speed 120km / h test the reliability of the Joint Working Group, systems analysis, to find a comprehensive circular line reliability tests appear in the cause of the problem, the study measures to improve and ensure the 120km / h speed the safe operation of the technical program, the implementation of the Program, limit the use of maintenance and evaluation criteria.
In response to these vehicles in the test problems, the joint working group to work quickly, first of all 60 vehicles tested had the appearance of a comprehensive examination of the problems typical of 7 vehicles, a comprehensive testing and a break down in good Comparative testing of vehicles break down; many of the early dynamics testing, performance testing and detection, such as decomposition of a comprehensive data sort, summary and analysis; at the same time the use of static analysis and dynamic simulation of a comparative analysis of the calculation method of multi-angle analysis, Find factors to discuss the results of the analysis stage and improving the program, the main research work arrangements. In the full analysis, calculated on the basis of the discussions and put forward measures to improve the test and verification program for the organization and dynamics of the test.
