摘要
文章针对某车型悬架减振器异响问题,分别进行整车道路试验及台架试验。利用时频分析和功率谱分析的方法,得出减振器异响源是减振器本身和异响声音的频率;利用力锤模态试验求出减振器部件和组合部件模态固有频率,分析出异响噪声源。对减振器异响噪声控制方面和试验检测方面具有一定的指导意义。
The vehicle road test and bench test are carried out for a vehicle suspension shock absorberabnormal noise problem. The method of time frequency analysis and power spectrum analysis are used to get the frequency of shock absorber. The shock absorber components and composite components modal frequencies weregot by force hammer modal test, then the noise source was found. It has certain guiding significance for abnormal noise control and test aspect about shock absorber.
