穿戴式手枪射击稳定装置动力学仿真研究

STUDY ON DYNAMIC SIMULATION OF EXTRNAL BONE PISTOL SHOOTING STABILITY DEVICE

为减小手枪射击时射击轨迹与瞄准基线的偏差,以子弹运动的方向为X轴正方向,与X轴垂直向上的方向为Y轴正方向设计了一种基于上臂外骨骼方案的手枪射击稳定装置。该装置通过限制手掌在X和Y方向上的运动及手腕关节处的转动来实现减小抖动的目的。分析了人体关节的阻抗类型,建立了手掌在射击前和射击后以及穿戴与未穿戴稳定装置状态下的运动方程,通过动力学仿真软件ADAMS计算手掌在X和Y方向上的速度和位移。得到的仿真结果表明方案达到了预期效果,并且在Y方向对位移的作用效果显著。

In order to reduce the deviation between the shooting trajectory and the aiming baseline when the pistol is fired,a pistol stabilizer based on the upper arm exoskeleton scheme is designed in the direction of the X axis and the vertical upward direction of the X axis.The device achieves the purpose of stabilization by limiting the movement of the palm in the X and Y directions and the rotation of the wrist joints.The impedance types of human joints are analyzed,the motion equations of palms are established before and after firing,as well as in the state of wearing and not wearing anti-shake devices,and the velocity and displacement of palms in X and Y directions are calculated by dynamic simulation software.The simulation results show that the scheme has achieved the expected effect,and the effect on the displacement in Y direction is remarkable.
