为弄清影响手提式自动武器射击精度的主要因素,定量分析枪身在射击过程中的运动规律,必须知道人体的动力学特性和必要的动力学参数。本文推导了利用速度阻抗进行单自由度系统的参数识别方法;建立了卧姿抵肩射击时人体上半身躯的动力学模型;最后根据实测的试验数据,利用本文所述参数识别方法,求出了在卧姿射击过程中人体上半身躯的一些动力学参数。
In order to understand the main factors affecting the precision of hand-firing automatic weapons, the kinematics of the gun body during shooting process must be quantitatively analyzed. The dynamic characteristics of human body and the necessary kinetic parameters must be known. In this paper, the method of parameter identification of the single-degree-of-freedom system using velocity impedance is deduced. The dynamic model of human upper body when lying shoulder-to-shoulder shooting is established. Finally, based on the measured experimental data and using the parameter identification method described in this article, Some kinetic parameters of the upper body in the human body during a lying position.
