高频点射步枪动力学仿真分析

为提高步枪的命中概率,研究了一种新概念高频点射枪弹和高频点射步枪.基于凯恩多刚体动力学理论,建立了射手与步枪系统的发射动力学模型,进行了高频点射步枪人杌耦合系统发射动力学的数值仿真,得到了射手及步枪等效体在发射过程中的运动参敷.分析了连发射击过程中枪管位置状态的变化情况,从理论上证明了步枪以高频点射方式发射时能够有效控制射弹散布.分析结果表明,在提高命中概率方面,高频点射步枪比传统步枪有优势.

Dynamic Simulation Analysis for High-frequency Burst Rifle

In order to improve hit probability of rifle,the high-frequency burst cartridge and rifle of new concept was investigated.Based on Kane's dynamics theory of multiple rigid body,the firing dynamic model was established for the coupling system of firer and rifle,and dynamic numerical simulation of the system was carried out.The launching motion parameters of equivalent bodies of firer and rifle were obtained.The location change of barrel was analyzed in the state of automatic firing.Bullet dispersion of rifle...
