摘　　要：根据高压气动弹射装置的工作原理和特点,结合实际应用给出了无缓冲腔、采用缓冲腔、采用多组高速开关阀等3种弹射装置方案,基于气体动力学理论,采用分段建模的方式,构建了内弹道方程组,计算分析了弹射装置主要参数对弹射体出筒速度、弹射过程最大瞬时过载等的影响。仿真结果表明,采用缓冲腔、采用多组高速开关阀2种方案的弹射装置均可有效降低弹射体的最大瞬时过载、提高出筒速度,且采用多组高速开关阀的效果最好。研究结果可为高压气动弹射装置的优化设计、制造与试验,提供借签。According to the operating principle and characteristics of high-pressure pneumatics ejection system,three kinds of ejection devices are given,including ejection system standalone,ejection system with cushion chamber and ejection system with high-speed on-off valve.Interior ballistics model is established using aerodynamics theory and segmentation modeling method.On the basis,different parameters on leaving velocity and max-overload are calculated and analyzed.The simulation results show that,ejection system with cushion chamber and ejection system with high-speed on-off valve can both effectively reduce max-overload and increase leaving velocity.The best scheme is the one with high-speed on-off valve.The research production can guide the optimum design,manufacturing and experiment of high-pressure pneumatics ejection system.
