摘要: 为定量分析船载转塔装置(STE)随动控制过程中随动力矩的影响因素,应用坐标变换原理和拉格朗日动力学方程,建立了STE随动系统运动学和动力学模型。针对不同摇摆角和目标运动状态,对STE随动过程进行动力学仿真,定量分析了摇摆角及目标运动对随动力矩的影响。仿真结果表明:随着摇摆角幅值和周期的变化,随动力矩呈现线性变化趋势,且周期的影响更加明显;摇摆角幅值每增加1°,方位轴、俯仰轴随动力矩分别增加约12%、2%;周期每增加1 s,方位轴、俯仰轴随动力矩分别减小约28%和6%。摇摆角之间的相位间隔对随动力矩的影响具有复杂性,需要对不同相位区间进行分析。相对于静止状态,目标运动会引起随动力矩的增大,且加速度对随动力矩的影响更加明显。

Abstract: A kinematics and dynamics model of a ship-borne turret equipment (STE) was constructed using coordinate transformation principle and Lagrange dynamic equations. The proposed model is used to analyze the influence factors on servo torque of STE in servo control. The servo control process of STE under different swing angles and target motion state was simulated, and the influences of swing angles and target motion state on servo torque were analyzed quantitatively. The simulated result shows that the servo torque varies almost linearly with the change in the amplitude and period of swing angle, and the effect of period is more obvious. When the amplitude of swing angle is increased by 1 degree, the servo torques of azimuth and elevation axes are increased by about 12% and 2%, respectively. When the period is increased by 1 s, the servo torques of azimuth and elevation axes are decreased by about 28% and 6%, respectively. The impact of the phase difference between swing angles on servo torque is complicated, and therefore the different intervals of phase difference need to be analyzed. Compared with the stationary state, the target motion causes the increase in the servo torque, and the impact of acceleration on servo torque is more evident. Key
