摘要
利用灵敏度分析的方法,定量地研究了机枪的结构参数变化对其动力学特性的影响关系,获得了影响机枪动力学特性的敏感部位和敏感参数。在此基础上,利用结构动态修改的方法,以改善机枪动力学特性为目标,对敏感参数进行了修改,达到了机枪动力学特性优化设计的目的。
In this paper, the relationship between variations in structural parameters and dynamic characteristics of machine guns is analysed quantitatively with the method of sensitivity analysis, and the sensitive points and relevant parameters of the machine gun are found. On this basis, these sensitivity parameters can be modified through optimization and an optimum design of the dynamic characteristics of machine guns is obtained.
