摘　　要：为了研究人体作用对武器射击后坐运动产生的影响,根据人体射击运动的特点和规律,将抵肩射击人枪模型简化为由手臂等效质量和武器组成的两刚体两自由度模型,将人体对武器的作用简化为等效弹簧和阻尼器的缓冲作用.通过数值仿真计算,得到与实验相似的结果.对系统模型中人体的作用参数进行灵敏度分析,辨识出影响武器后坐运动的主要人体因素.In order to study the impact of human action on the recoil of weapons firing,base on the characteristics of body movement during shooting,the arms and weapon were simplified into two rigid body with two degrees of freedom,and the interactions between human and weapon was simplified into effect of a system with equivalent springs and dampers.The results of numerical simulation is similar to the experimental results.By parameters sensitivity analysis,the main factors on impact of weapons rearward motion were identified.
