摘要
针对地铁车辆在转向架附近范围内存在异常振动冲击现象 ,进行了整组列车运行状态振动情况测试和转向架单独室内动态特性测试 ,找到了产生振动冲击的原因 ,揭示了这一现象的产生机理 ,为消除这种异常振动冲击现象提供了理论依据。
For there is abnormal vibration impact near the bogies of metro cars, the testing of vibration in operation of the whole car and the indoor testing of dynamic features of separate bogies are carried out. The causes to the vibration impact are found out, and the mechanism to cause the phenomenon is disclosed. Thus, the theoretical basis is provided to eliminate the abnormal vibration impact.
