摘要

为研究某型车载转管机枪在外部激励作用下的振动特性，利用虚拟样机技术对该武器系统进行强迫振动分析。分析该型机枪系统拓扑结构及所受载荷，利用ADAMS软件建立车载转管机枪的刚柔耦合模型及武器振动方程，用所建立虚拟样机模型对车载状态下转管机枪的振动特性进行仿真测试，主要研究路面激励与车辆行驶速度激励，获得机枪系统在不同激励下的振动。计算结果为车载机枪试验与进一步参数匹配优化及提高机枪射击精度奠定基础。

Abstract

To study vibration characteristics of certain vehicular Gatling gun under external excitation, virtual prototype technique is proposed to analyze forced vibration of this gun system. Firstly the topological structure of the gun system and the loading are analyzed, and rigid-flexible coupling model of vehicular Gatling gun is built with ADAMS. Then, the weapon's vibration equations are established. Virtual prototype model is used to simulate and test vibration characteristics of vehicular Gatling gun. Road surface excitation and vehicle speed excitation are especially researched to get the vibration response under different excitations. The calculation results provide reference for vehicular gun test and parameter matching and optimization, which lay the foundation for improving the firing accuracy.
