铁路客车的振动对旅客和车辆本身带来了严重的不良影响,已引起了有关部门的高度重视.对我国准高速铁路客车的振动进行了车内测试.并对其测试结果进行了分析,从而得出结论:车体振动主要表现形式为横向振动和垂向振动,铁路客车抖动的原因主要由共振引起. The vibration of railway passenger cars has brought serious adverse effects on passengers and vehicles themselves and has aroused the attention of relevant departments.Analysis was made on the vibration of passenger cars in China’s quasi-high-speed railway and the test results were analyzed. It is concluded that the main manifestation of vehicle body vibration is transverse vibration and vertical vibration. The reason of railway passenger vehicle vibration is mainly caused by resonance.
