摘　　要：为研究采用浮动发射技术的高初速榴弹发射器射击时与人体相互作用,参照中国成年人人体尺寸国家标准,建立19刚体、52自由度的人体模型,结合单发卧姿抵肩射击的特点,建立人枪系统发射动力学仿真模型。分析自动机在人枪系统发射过程中的运动特性及人体重要关节的受力特性,总结人体重要关节在不同参数下的受力响应规律,给出降低人体关节受冲击载荷的若干途径。仿真结果表明,该模型可以预估榴弹发射器对人体关节的冲击效应,为新枪的研制提供必要的仿真依据。In order to study the interaction between high muzzle velocity grenade launcher when launching with floating launching technique and human body,combined with single shot characteristics with prone-shoulder,a launching dynamical simulation model of man-gun system is set up referring to the national standard, human dimensions of Chinese adults. The moving characteristics of automatic mechanism and forces characteristics on important human joints are analyzed. Forces response law on important human joints is summarized in the case of the different parameters. A number of avenues which can reduce the impact load on human joints are given. Simulation results show that the impact effect on human joints which comes from grenade launcher can be estimated effectively,the necessary simulation foundation is provided for research and development of the new gun.
