【摘要】 轻武器立姿射击过程中,射手的控制因素对武器射击稳定性影响明显,为了研究人体肩部和腰部的控制作用对某榴弹发射器射击稳定性的影响,根据武器射击运动的特点和规律,将抵肩射击系统简化为由武器等效质量和躯干等效质量组成的两刚体五自由度人枪作用模型,将人体上肢对武器的控制作用和人体对躯干的控制作用分别简化为肩部和腰部等效弹簧和阻尼器的作用。通过对各等效作用参数的仿真计算,获得相应的武器射击运动曲线。仿真试验结果表明,人体肩部和腰部的不同控制作用对武器射击稳定性具有不同程度的影响,为智能枪架设计中相关人体作用参数的控制提供了理论参考。更多还原

【Abstract】 Control factors of a shooter have a significant impact on firing stability of a weapon in shooting process.In order to study the control effect of shoulder and waist on firing stability of a grenade launcher,a man-weapon system model with shoulder supported was developed. According to the characteristics of shooting,the human body and weapon were simplified into two rigid bodies with 5-DOF. The acting forces on shoulder and waist were simplified into the actions of equivalent springs and dampers. Through simulating with different values of equivalent parameters,the results showed that different controls of the human body have different influences on firing stability of weapon; the equivalent parameters of waist and the pitch damping coefficient of shoulder are critical for the design of intelligent firearm mounts.更多还原
