摘要

为了研究士兵立姿无依托射击过程动态响应特性,在AnyBody人体肌骨建模平台中建立了人—枪系统模型。采用三维运动捕捉系统捕获了射击姿态,以实验数据驱动人枪模型。通过肌肉活动度最大/最小模型解决肌肉募集冗余问题,基于逆向动力学原理,计算射击过程中肌肉发力和人体关节受力规律。结果表明:对于手枪在立姿无依托连续射击过程,同时也是行为意识学习过程,射击结束后肌群会本能的按照上一次射击所需的预紧力进行有规律的收缩;对于每一次射击过程,肌肉及关节受力会有3个波峰,前2个波峰是由于手臂随着枪械被动运动造成的,最后1个波峰是主动控制造成的,从击发到主动控制需要243ms;射手在连续4发射击后,肌肉的疲劳会迅速加剧。研究结果对射击训练和手持轻武器效能的最佳发挥提供了科学参考。

Abstract

The purpose of the study was to investigate the response characteristics of soldiers standing without support during the pistol shooting, a man-gun system model was established based on AnyBody software platform. A man-gun system model was drived by the Kinematic data which obtained by the three-dimensional motion capture system. The model was analyzed using the inverse-dynamics approach, while the “minimum-fatigue” criterion was utilized to deal with the muscle redundancy problem. The results obtained show that behavior consciousness has been studied in the process of shooting and muscles will instinctively shrink according to the tightening force of the last firing. In the process of shooting, 3 peaks are found, the first 2 peaks is due to passive movement caused by firearms, the last 1 peak is caused by the active control, from passive to active control needs 243ms; Muscles fatigue will rapidly intensified after 4 consecutive shots. This paper provides referrence to shooting practice and optimum exertion of general efficiency of handheld small arms.
