摘要
随着现代机枪不断轻量化，了解其结构动态特性对研究射击精度非常重要。搭建基于LMS的模态分析试验系统，进行硬件、软件及激振系统的配置，对某型机枪进行模态试验，并对测试数据进行分析，其结果对于进一步改进机枪结构动力特性提供了理论依据。
With the modem machine gun＇s increasing light mass, it is very important to get its dynamic characteristic for their firing accuracy. The modal analysis experiment based on LMS is built with the hardware, software and the excitation system configured. The modal test is experimented for a machine gun and the test data is also analyzed. The results provide theoretical basis for further improving the structure dynamic characteristic of the machine gun.
