摘要
从青藏线的地理环境特点分析了可能影响车辆动力学性能的因素。通过对青藏线和兰新线上同一类车型的动力学性能试验数据对比分析,说明了青藏铁路线路条件对车辆动力学性能的影响;基于现有的试验数据资料,分析了不同气候条件下车辆动力学性能的变化特征。最后通过总结阐述了青藏线综合环境条件下铁路货车动力学性能的变化特点,并为可能进行的青藏线大件运输或大型军事装备运输的安全监测提出了建议。
This article analyzes some characteristics that may affect dynamics performance of vehicle from geographical environment of Qinghai-Tibet Railway.Through comparing experimental data between Qinghai-Tibet Railway and the Lan-Xin Railway for the same vehicle,the article indicates the conditions of the Qinghai-Tibet railway how to affect vehicle dynamic performance,and then analyzes the characteristics of performance changing under different climate conditions based on existing test data.Finally,the dynamic performance characteristics of railway trucks in Qinghai-Tibet Railway are summarized,and the recommendations are proposed for safety monitoring of large-scale or special military equipment transportation in the future.
