120 km/h货车提速综合试验动力学性能分析

我国提速综合试验既是对列车在提速条件下对线桥设备(包括钢轨、轨枕、道岔、路基、路桥过渡段和桥涵等)的动力作用的试验,又是对车辆动力学性能进行的一个充分的验证性能试验。文章通过对比分析近年来我国提速综合试验的测试线路、试验车辆、运行特点和测试数据,对我国综合提速试验中120km/h货车动力学性能进行了比较全面的总结与分析,指出了我国120km/h货车动力学性能方面存在的主要问题,并提出了解决问题的建议。

Analysis of Dynamics Performance of the 120 km/h Speed Increased Comprehensive Testing Freight Cars

The speed increased comprehensive test in our country is both the test on the dynamic application of the speed increased trains on track and bridge equipment (including rail, sleeper, switch, bed, track-bridge transition section, bridge and culvert), and the ample performance-verifying test on the dynamics performance of rolling stock. In this paper, through the comparison and analysis of testing track, testing vehicles, operation features and testing data in the speed increased comprehensive test in our country in recent years, a fairly complete summary and analysis is made on the dynamics performance of the 120 km/h freight cars in the speed increased comprehensive test in our country. The main problems existing in the dynamics performance of the 120 km/h freight cars in our country are pointed out, and suggestions to solve the problems are given.
