印制板模态测试方法研究

Study on Modal Testing Method of PCB

通过研究模态测试理论,针对不同试验目的对印制板进行自由模态方法和约束模态方法的研究,对约束方式的选择与搭建、锤击方式的选择、传感器的布置等进行了详细介绍,可为印制板模态试验提供指导。

In the paper,by studying the theory of modal testing,the free modal method and the bundled mode of the PCB used in different goal are studied.The selection and construction of constraint mode,hammering mode,sensor arrangement and other aspects are introduced in detail,which provides method guiadnce for PCB modal testing.
