摘要
根据Hanavand的15刚体人体模型,通过对人体立姿射击姿态进行简化,按照人体基本几何比例参数,建立力学结构中的多刚体铰接系统模拟人体立姿射击,基于人体各个关节的自由度参数建立系统约束条件的假定和分析,建立系统的力学方程,借助于ADAMS仿真软件的运动学和动力学分析功能,对立姿射击姿态进行了完整的建模,通过对立姿射击姿态的仿真,从立姿支撑面和腰部强度两个方面对模型施加外部控制,模拟子弹激发瞬间人体运动,分析运动中枪口位移和腰部受力、力矩的曲线图,提出了提高姿态稳定性的方案。
According to the Hanavand 15 rigid body modeling, this paper predigests the model of standing shooting position based on multi-body dynamics, then the standing shooting position model is built up in ADAMS. The standing shooting process is simulated to find the method of improving the stability and shoot straight of standing shooting position. By analyzing the function of ADAMS, the author built up the standing shooting position integral model. Through simulating the body movement as bullet explodes, it analyses the graph of the muzzle displacement, waist moment and waist force. Finally, the method for improving the stability of standing shooting is put forwarded.
