人枪系统参数对射击精度的影响

为使人枪系统具有最佳的匹配效果和客观评价枪械的射击性能，对影响人枪系统射击精度的参数进行研 讨。根据单发卧姿有依托抵肩射击的特点，以多刚体系统动力学为理论基础，应用UG 软件，建立模拟人体枪架发 射动力学仿真模型，分析自动机在人体枪架发射过程中运动特性对枪口位移的影响，得出射击精度实验结果，对影 响射击精度的导气孔直径和复进簧刚度进行分析。仿真分析结果验证了该模型的可行性和有效性。

Effect of Human Gun System Parameters on Firing Accuracy

In order to make the human-gun system has the best matching effect and to objectively evaluate the firing performance of the gun, the parameters that affect the firing precision of the human-gun system are discussed. According to single prone position has the characteristic of relying on over shoulder shooting, based on the theory of multiple rigid body system dynamics, the application of UG software, the simulated human body gun launch dynamics simulation model is established, analysis the effect of the movement characteristics of the automaton on the muzzle displacement during the firing of the human body gun frame, get the results of firing accuracy experiment, gas guide hole diameter and the complex spring stiffness which influence on firing precision are analyzed. Simulation results verify the feasibility and effectiveness of the model.
