| 摘 要： | 提出了基于MATLAB/Simulink的逃逸飞行器与运载火箭应急分离六自由度仿真方法,建立了其应急分离的数学与动力学模型,并应用MATLAB/Simulink的系统仿真功能,实现了逃逸飞行器在特定初始条件下与运载火箭分离的六自由度仿真。仿真结果表明:基于MATLAB/Simulink的逃逸飞行器与运载火箭应急分离六自由度仿真方法是可行的,通过对逃逸主发动机推力以及逃逸塔结构弹性变形的分析,可以为逃逸飞行器的方案设计提供参考。

| Abstract: | A 6-DOF simulation method for emergent separation between the escape vehicle and the carrier rocket is presented based on MATLAB/Simulink.The mathematical and the dynamics model of the emergent separation is established.The 6-DOF simulation of the separation between the escape vehicle and the carrier rocket under the special initial conditions is conducted by Matlab/Simulink with simulation.Results show that the simulation method of the emergent separation based on Matlab/Simulink is feasible.The primary reference for the conceptual design of the escape vehicle is provided by analyzing the thrust of the escape main engine and the structural elastic deformation of the escape tower. |
