120km/h Of Carry Rapid Car Reliability Test Part Research

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.
