气室冲量模拟器建模与仿真研究

气室冲量模拟器是导气式自动机模拟试验系统的核心部件，其动力学特性决定了该系统是否可以模拟武器实弹射击时的气室火药燃气压力冲量。以某14．5mm高射机枪为例，对气室冲量模拟器进行了气体动力学仿真。介绍了气室冲量模拟器的工作原理，根据气体动力学和热力学理论，利用经典龙格一库塔法建立了气室冲量模拟器活塞运动的数学模型，并应用MATLAB编程求出了数值解，将仿真结果与实测结果进行对比，得出该气室冲量模拟器可以被用来模拟气室冲量，完成模拟射击试验。

Study on Modelling and Simulation of Gas Chamber Impulse Simulator

Gas chamber impulse simulator is one of the core parts of gas operated automatic mechanism in the simulation test system,and its dynamics characteristics have very important influnce on whether this system can simulate gun powder gas pressure impulse in actual ball firing process of weapon.Taking the 14.5 mm anti-aircraft machine gun as the example,aerodynamics model of the gas chamber impulse simulator was simulated. The principle of the air chamber impulse simulator was introduced. According to the theori...
