摘要
分析部件变形对转管机枪枪口扰动的影响程度,有利于武器系统的结构设计与优化。为研究不同部件对转管机枪枪口扰动的影响程度,以某型转管机枪武器系统为研究对象,基于多体系统动力学,建立了刚柔耦合虚拟样机模型。通过对该模型中易变形的单一部件进行柔性化,从而建立不同仿真工况,分别与多部件柔性化的仿真工况进行枪口振动比对分析。结果表明:单一部件柔性化时,摇架变形引起枪口位移最大,依次是托架、支架、身管,摇架引起枪口高低角位移为1.395 mrad,多部件同时柔性化引起的枪口角位移为1.316 mrad,摇架比多部件柔性化引起的枪口高低角位移大6%,多部件柔性化可以降低该武器的枪口角位移。结果为该武器系统的结构优化设计提供了参考。
Analyzing the degree of influence of component deformation on muzzle disturbance of rotary-barrel machine guns is conducive to the structural design and optimization of weapon systems.In order to study the degree of influence of different components on the disturbance of the Gatling gun muzzle,a rigid flexible coupling virtual prototype model is established based on Multibody System Dynamics for a certain type of Gatling gun weapon system.By flexing a single component that is prone to deformation in the model,different simulation conditions are established,and the muzzle vibration is compared and analyzed with the flexible simulation conditions of multiple components.The results show that when a single component is flexible,the deformation of the cradle causes the maximum displacement of the muzzle,followed by the bracket,stand,andbarrel.The cradle causes a muzzle high and low angle displacement of 1.395 mrad,while the simultaneous flexibility of multiple components causes a muzzle high and low angle displacement of 1.316 mrad.The cradle is 6%more than the flexibility of multiple components,and the flexibility of multiple components can reduce the muzzle angle displacement of the weapon.This result provides a reference for the structural optimization design of the weapon system.
