摘要
利用脉冲激励法对某２５０型摩托车车架进行了试验模态分析，并介绍了试验模态分析的方法和设备；所得模态分析结果可为车架的结构设计及整车的振动分析提供依据。
The pulse-excitaion method and the equipment for modal test are introduced. A test modal analysis of the motorbike frame has been completed. The result will be delivered to the design department of the frame structure and will be helpful to vibration analysis of the motorbike.
