机载机关炮发射动力学建模与仿真

Model and Simulation of Launch Dynamics of Automatic Cannon in Helicopter

应用多体系统传递矩阵法,建立了刚弹耦合的机载机关炮(简称航炮)发射动力学模型;推导了航炮系统的特征方程;建立了航炮的发射动力学方程;编制了航炮的发射动力学仿真程序,进行了航炮的发射动力学仿真,得到了一系列有用的仿真结果。对航炮的动态设计及系统改进具有一定的指导意义。

Launch dynamical model that coupled with rigid and elastic body for automatic cannon in helicopter was established based on transfer matrix method of multibody system. System characteristic equation was derived and launch dynamical equation was established, Simulation code was written. A lot of useful simulation results were obtained which could improve system capability and instruct weapon design.
