本文为测试蜗杆凸轮机构输出端的角加速度响应设计了一套测试系统，并用该系统进行了测试。测试结果与理论计算结果对比表明，对蜗杆凸轮机构建立的二自由度振动模型所导出的输出端响应公式，将能满足该机构动力学的设计与分析，该测试系统还可用于类似机构和装置的测试。
In this paper, we designed a test system for testing the angular acceleration response at the output of the worm cam mechanism and tested it with this system. The comparison between the test results and the theoretical calculation results shows that the output response formula derived from the two-degree-of-freedom vibration model established by the worm cam mechanism will be able to meet the design and analysis of the mechanism dynamics. The test system can also be used for similar mechanisms and devices Test.
