针对传统振动测试方法不能实现可视化振动测试且测试周期长的问题，提出了基于激光多普勒原理的引信微小型结构件振动测试方法。该方法根据引信微小型结构件振动模型和服役环境振动频率的特征，通过一定范围的扫频振动信号和基于激光多普勒原理的测试系统，在一个较短的测试周期内完成对引信微小型结构件在运输、发射、飞行这三个环境下的振动测试，可以快速得到其振动速度和振动位移等参数并且能够实时观测被测物体的模态变化情况。仿真验证表明：利用基于激光多普勒原理的振动测试方法对引信微小型结构件进行快速、可视化振动测试是可行的。

In view of the shortage of traditional vibration testing methods for fuze micro structure,a method based on laser Doppler vibration testing principles was presented in this paper.The method was based on the model and the vibration frequency of the service environment features,which swept through a range of vibration signals and completed vibration test in a short cycle.The vibration velocity and vibration displacement parame-ters of simulated environments of transport,launch and flight could be obtained quickly by this method,which meant the method for fuze micro structure vibration test was feasible.
