摘要
针对某客车开发过程中出现的拍频问题,基于整车振动试验,采用频谱分析法和分别运转法确定产生拍频现象的原因,并作出相应的改进,最终明显减轻了拍频现象。
In view of the beat-frequency problem of a bus in development process,this paper uses methods of frequency spectrum analysis and respective operation to determine the reason for the beat-frequency phenomenon of a bus based on the vehicle vibration testing,and makes corresponding improvement.At last,the beat-frequency phenomenon is reduced obviously.
