客车车内轰鸣声优化改进

Optimization and Improvement of Boom Inside Coach

基于传递路径分析和模态分离方法,优化响应点振动和传递路径,减少各中间环节响应,有效降低客车行驶轰鸣声,并提出降低客车行驶轰鸣声的设计思路。

Based on methods of transfer path analysis and mode separation,the vibration and transfer path of response points are optimized to reduce the response of each intermediate link,and effectively lower the running boom of the coach.Finally,the design ideas of lowering the running boom of the coach are put forwarad.
