摘要
以某型车载转管机枪为对象,为了研究高低两种射频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。考虑转管机枪射击时各部件的运动关系和受力情况,对机枪的工作原理和系统拓扑机构进行了分析说明。综合考虑轮胎与地面、车体与机枪之间的相互作用,仿真模拟了机枪的射击试验过程。对机枪在高、低两种射击频率条件下进行了系统动力学分析和外弹道计算,获得了机枪的动态响应特性和立靶散布情况。通过对试验数据和仿真结果的对比分析,得出机枪射频对射击精度的影响关系。
To study the influence of high and low fire frequencies to the firing accuracy on a certain vehicular Gatling gun, a virtual simulation with rigid-flexible coupling was established. Considering the movement and the forces of the various components of the Gatling gun, machine gun working principle and system topology institutions were analyzed. Considering the interaction of the tires and road surface, vehicle and machine gun, the prototype firing test was simulated. The dynamic analysis and calculation of exterior ballistics were completed in the high and low fire frequencies conditions, and the response characteristics and vertical-target dispersion were obtained. Through comparative analysis of the experimental data and simulation results, the influence of fire frequency to the firing accuracy was obtained.
