摘  要:针对导弹从内埋武器舱发射过程中存在的气动与运动紧密耦合的问题,为获得准确的弹道参数并进行控制,结合Fluent和Simulink各自的优点,利用Fluent的Journal文件和Simulink的S函数,通过共享数据文件的方式开发了两者的数据接口,建立了并行协同仿真平台。建立了通过舵面控制导弹运动的模型,对比仿真了导弹在无控和闭环控制情况下从内埋武器舱发射时的空气动力特性和弹道特性。仿真结果验证了并行协同仿真的可行性,表明舵面控制能够有效改善内埋导弹的初始弹道特性。In order to solve separating from cavity, and in the dynamic and kinematic tight coupled problem existed during order to acquire accurate trajectory parameters for control system, a missile parallel collaborative simulation platform was established based on Fluent and Simulink. The Journal file of Fluent and S-function of Simulink were adopted, and the data interface between Fluent and Simulink was developed by sharing data file. The missile's rudder control model was established. The aerodynamic characteristics and trajectory characteristics during missile separating from cavity were simulated under uncontrolled and closed- loop controlled conditions. The simulation results verify the feasibility of parallel collaborative simulation and show that rudder control method can effectively improve the ballistic trajectory characteristics when missile separating from cavity.
