摘要
在试验模态分析中力锤与激振器是最常用的两种激励手段,两种激励方式在模态测试中各有优缺点。以动车组轮对试验模态为例,说明力锤激励与激振器激励模态试验配置及注意事项,分析其异同,通过试验得到包含重根在内的多阶模态结果。
Exciter and hammering are the two most common excitation methods in the experimental modal analysis, and each of them has its own merits and demerits. Taking the wheelset experimental modality of MU as an example, the configuration and attention of exciter excitation and hammering excitation modal test are explained, and the similarities and differences are analyzed. The multi-order modal results including multiple roots are obtained via experiments.
