摘　　要：红宝石脉冲激光器和外同步触发信号结合实现了齿轮轮齿动态散斑图的记录.用精确的时间延时得到齿轮轮齿完整啮合过程的二次曝光散斑图,经图像自动处理系统分析,获得了轮齿完整啮合过程的动态变形.实测值与有限元计算结果的变化趋势一致.Dynamic speckle photography of the gear tooth has been achieved by combining a pulsed ruby laser with the external synchronizing trigger signal. Double speckle photograms of the whole mesh period of gear tooth are obtained by accurate time delay. Gear tooth dynamic deformation of the whole mesh period is achieved using the automatic image processing. Testing results show that the trends of gear tooth deforamtion coincide with the calculated ones by the finite element method. The success of the testing provides a new way for the measurement of the rotating gear tooth dynamic deformation.
