为了研究鸭舵式修正机构舵偏角的选择方法,建立了不同舵偏角下弹丸的三维模型,并利用FLUENT和ADAMS软件进行联合仿真,得到了不同舵偏角下弹丸的空气动力数据和飞行稳定性特征。同时,研究了不同舵偏角对电机控制能力和鸭舵修正能力的影响,并进行了MATLAB仿真。结果表明,在满足全弹气动布局、飞行稳定、电机有效控制、弹丸修正能力的基础上,尽量选择舵偏角大的舵翼结构。

In order to research on selection method of canard deflection angle correction mechanism, 3D model of different canard deflection angle of projectile was established, FLUENT and ADAMS were co-simulated and aerodynamic and flight stability characteristics under different deflection angle projectile were obtained. Meanwhile, the effects of different deflection angle on motor control and correction capabilities were studied with the MATLAB simulation. The results show that based on aerodynamic layout, flight stability, effective control, motor projectile correction ability, canard structure with larger deflection angle should be selected.
