摘要

兰新铁路客运专线地处我国西北地区，高温、严寒和多风沙的自然环境对高速动车组安全可靠运营提出较高的要求。动车组以200 km/h的速度运行时车辆状态良好，当提速至250 km/h后动车组的动力学指标（如构架横向振动加速度和横向平稳性）明显恶化，在局部区段接近相关标准要求限值。文章从车轮磨耗、实际轮轨匹配关系和运用环境角度出发，利用仿真分析和振动测试的方法分析引起车辆动力学性能恶化的原因，并通过改善钢轨廓形、优化悬挂参数和调整车辆运行交路提高车辆横向运行稳定性，解决动车组提速后出现的动力学问题。

Abstract

The Lanzhou-Xinjiang passenger dedicated Line is located in the northwest region of China with the natural environment of high temperature, severe cold and windy sand, which puts forward higher requirements for the safe and reliable operation of high-speed EMUs. When the running speed was 200 km/h, the EMUs operated in good condition. After the speed was increased to 250 km/h, the dynamic indicators such as the frame lateral acceleration and lateral ride index would significantly be increased, and be close to the limit values in some conditions. From the perspective of wheel wear, actual wheel-rail matching relationship and application environment, simulation analysis and vibration test were used to find the cause of the deterioration of vehicle dynamic performance. the lateral stability was improved by improving the rail profile, optimizing suspension parameters, and adjusting operation routes, the vehicle dynamic problems were solved well after the EMUs speed increase.
