摘　　要：为解决某高初速自动榴弹发射器减后坐及轻量化问题,提出一种将前冲击发原理运用于高初速自动榴弹发射器减后坐方案,建立其虚拟样机动力学仿真模型。通过对武器系统三连发射击过程仿真计算,得出榴弹发射器自动机运动曲线及三脚枪架在冲击载荷下受力响应曲线。分析浮动体质量、射角、传速比、浮动行程对自动机运动特性的影响并揭示最大后坐力的变化规律。仿真结果表明,将前冲击发原理应用于高初速自动榴弹发射器原理是可行的,合理匹配枪械结构参数,可以将高初速自动榴弹发射器的最大后坐力控制在3500N以下。To solve the problem of reduction recoil and light weight of high initial velocity automatic grenade launcher（HIVAGL）, a reduction recoil project of HIVAGL using forward-rushing firing principle was presented, and the virtual prototype dynamics simulation model of HIVAGL was established. The motion curves of automatic mechanism and stress response curve of gun tripod under the action of the impact load were calculated through the simulation computation three volleying shooting process of weapon system. The effect of floating body quality, firing angles, speed ratio and floating distance on automatic mechanism motion characteristics was analyzed, and the rule of maximum recoil of HIVAGL was revealed. The simulation results show that the forward-rushing firing principle which was used on HIVAGL can be realize and the maximum recoil of HIVAGL can be limited under 3500N through matching structure parameters of gun.
