推力矢量燃气舵的受力分析及其模拟实现

Force Analysis and Simulation of Et Vane of Thrust-Vector

在大量试验的基础上,首先进行推力矢量燃气舵受力分析,论述了推力矢量燃气舵和弹体间的相互作用关系,推出了力与力矩相互转换的转换矩阵,并应用该转换矩阵推导出燃气舵坐标系下的驱动铰链力矩。其次,对舵机系统进行大量模拟试验,以验证舵机系统在受到燃气舵力和力矩综合作用下的正确性,针对推力矢量舵机的受力情况提出了其模拟实现的初步方案。

Based on the plenty of experimentation,the paper firstly analyzes the force of the thrust vector et vane,then discusses the relation of the force and the moment between the et vane and the missile.The matrix which will be used as the transmitted matrix,and the driving moment in the vane coordinate system are deduced.Then,a lot of related simulated research is made to confirm the et vane's force and moment,and the principium of the simulation for the et vane's force is brought forward.
