Study On The Dynamic Characteristics Of The Gun Firing

Pistol as an important individual self-defense, Plays an important role in its applicationfield, but the pistol firing caused by trigger force shaking the gun would have seriouslyaffected their shooting accuracy.This paper analyzes the dynamic characteristics of pistolshooting from many aspects to solve how to improve the firing accuracy of the gun in thebattle, improve the man-machine function of handgun used.System with one hand holding the pistol shooter firing the pistol and interaction as theresearch object, based on the study of human movement science physiology and ergonomicsand other subjects, combined with human biomechanical structure characteristics, presented apistol shooting one-handed pistol system model. The model consists of the human arm, handand the gun body, use three dimensional modeling software UG grasped when the pistolfiring to the list hand-hold the human gun system overall structure has carried on the entitymodeling, using dynamic simulation software ADAMS pistol firing gun-man system is avirtual prototype modeling, in every joint of the arm spring damping imposed constraints onthe human body, by altering the spring damping factor, analyzed the wrist and armmovements of human arms effects on pistol shooting accuracy. Through the change triggerpull infliction size and the angle, simulated the pistol to carry on the fire instantaneous, inunder trigger pull function pistol muzzle vibration situation; Passes through to the human gunsystem dynamics characteristic system analysis, has obtained the influence firing accuracyreason.Some of the shooters of different physical fitness and training status of air gun firing test,obtained the different experimental curve of air gun shooter gun when the angle change oftest data and the muzzle displacement. Through the comparative analysis of the experimental results, obtained the reasons of different muzzle jitter, and analyzed the muzzle jitter causedby the influence on firing accuracy.Through comparing the simulation curve and the analysis of experimental results,verified the correctness of the simulation results, summed up the impact of pistol firing beforethe moment by the trigger force causes the firing accuracy, and proposes specific solutions forthe cause. The research content of this paper is to provide theoretical support for thedevelopment of new pistol, and has the certain reference value to the army and the publicsecurity organs of pistol shooting training and ergonomics design for gun.
