|
摘要
选用某车用减震器橡胶衬套为试验对象,分析幅值和频率对衬套的动态性能影响。通过MTS衬套试验机对测试件进行动态特性试验。首先控制试验力幅值为某一常量,改变加载在测试件上的频率得出衬套动态特性参数的变化结果,分析频率对衬套的影响规律。通过改变试验力幅值来分析衬套动态特性随幅值的变化规律。最后,总结出频率和振幅对衬套动态特性的影响规律。
In this paper, a rubber bushing is selected as the test object, and the influence of amplitude and frequency on the dynamic performance of bushing is analyzed. The dynamic characteristic test of the test parts is carried out by the MTS bushing test machine. First,the amplitude of the test force is controlled to a certain constant, and the change of the dynamic characteristic parameters of the bushing is obtained by changing the frequency of the load on the test piece. The influence law of the frequency on the bushing is analyzed, and the amplitude of the test force is changed to analyze the dynamic characteristics of the bushing. The law of the change of the value is summed up. Finally, the effect of frequency and amplitude on the dynamic characteristics of bushing is summed up, which provides guidance for the study of bushing in suspension.
