摘要
根据自行高炮(SPAA)射击线稳定系统机械结构特点,以力矩电机直接驱动方式下轴间力矩特性为主要研究对象,应用动量矩定理及矢量叠加原理,系统地建立了SPAA射击线稳定系统的牛顿—欧拉动力学模型,对车体运动和射击冲击扰动条件下炮塔回转轴和火炮俯仰轴的动力学特性进行了仿真。仿真结果表明:车体运动对炮塔回转体的交叉耦合力矩为炮塔回转体受到的主要干扰力矩;方向轴控制力矩和俯仰轴干扰力矩随着射角增大而增大,高射角下的惯性力矩使方向轴控制力矩增加的速度更快;俯仰轴干扰力矩和低射角下的方向轴干扰力矩为相应轴控制力矩的主要组成部分。研究结果为SPAA射击线稳定系统的设计提供了依据。
According to the mechanical structure feature of firing line stabilization system of self-propelled antiaircraft （SPAA） gun, the shaft torque characteristics of torque motor in the case of direct drive are researched. The moment of momentum theorem and the superposition theorem are used to establish a Newton-Euler dynamic model for SPAA firing line stabilization system, and the dynamic characteristics of turret revolution body and gun elevation axis under the conditions of vehicle motion and shooting impact disturbance are simulated. The simulation results show that the cross coupling torque brought to the turret revolution body due to the vehicle motion is the main disturbance torque to which the turret revolution body is subjected, and the control moment of azimuth axis and the disturbance torque of elevation axis in- crease with the increase in shooting angle. The inertial moment at high angle makes the control moment of azimuth axis increases faster, and the disturbance torque of elevation axis and the disturbance torque of azimuth axis at low angle are the main components of corresponding shaft control moment. The results provide a foundation for designing of SPAA firing line stabilization system.
