摘要: 以某型车载转管机枪为对象,为了研究不同路面环境对其射击精度的影响程度,采用虚拟样机技术建立了该型机枪刚柔耦合多体动力学仿真模型。综合考虑了轮胎与地面、车辆与机枪之间的相互作用关系,仿真模拟了车辆处于自由状态时,机枪在不同路面条件下的射击过程并对其进行了外弹道计算,获得了机枪射击时车辆的振动特性、枪口的响应特性以及立靶散布情况。通过对各种路面条件下的仿真曲线对比分析,得出了路面环境对机枪射击精度的影响关系。研究结果为同类武器的研究与试验提供了理论支持和方向。

Abstract: To study the influence of firing accuracy on a certain vehicular Gatling gun in different road surface, a rigid-flexible coupling multi-body dynamic simulation model was established based on virtual prototyping technology. Considering the interaction relations between the tires and road surface, vehicle and machine gun, the vehicle vibration characteristics and the muzzle response characteristics and vertical-target dispersion were obtained by analyzing the machine gun system in different road surface. The influence of road surface on fire accuracy was demonstrated by contrasting and analyzing the simulation curves. The study results have provided a theoretical support and direction for the use of vehicular Gatling gun and test.

Key words: vehicular Gatling gun, rigid-flexible coupling model, road surface, dynamic characteristics, firing accuracy
