摘要

The current researches on characteristics of man-rifle interaction focus on the shooting process afterfiring without considering the laying stage before firing and the restoring stage after firing. To furtherunderstand the characteristics of man-rifle interaction in the entire process of rifle laying and firing, thisresearch comprehensively tests the entire process of standing firing without support. Also the researchproposes a comprehensive test method of man-rifle interaction experiment based on 3D motion capture andplantar measurement. This research divides the entire process of rifle fire into three stages of laying,shooting and restoring in action sequence. The result shows that, during the laying stage before firing, thestability of shooter’s holding rifle is affected by the place of holding, the weight of rifle and so on, which ispresented by slight shaking. Shooter’s control over rifle in the Y (horizontal) direction is obviously weakerthan that in the X (shooting) and Z (vertical) direction. The stability during this stage has a great influenceon the accuracy of first firing; During the firing stage, the period of 3-round burst is less than 300ms,so thathuman is in a passive and adaptive stage. Under the effect of impact among powder gas andfirearms-related parts, phenomenons can be seen that: muzzle displacement, plantar pressure centerdisplacement and speed all have a jump increasing along with the number of shooting, which is consistentwith the previous researches; And then man-rifle system will back to the laying stage after a restoring stageof about 0.8 seconds under human’s own control, which is influenced by human’s self-adjusting ability. Therestoring time is variable and it greatly affects the accuracy of shooting the objective again. This researchprovides theoretical reference and experimental basis for further revealing the mechanism of man-rifleinteraction, optimizing the ergonomics design of rifle and promoting the competence of soldier training andactual combat.
