针对反射镜稳定方式下的某型惯性稳定平台,考虑基座扰动、摩擦力矩、传动钢带的弹性和预紧力等影响因素,推导了系统的动力学方程,并在ADAMS中建立了系统的动力学模型。用Matlab/Simulink进行机电联合仿真,重点分析并得到了钢带在不同刚度和预紧力下对稳定精度的影响。研究结果为惯性稳定平台的设计提供了依据。
Considering the influence factors of pedestal disturbance, friction torque, transmission strip elasticity and pretightening force, a kind of inertial stable platform under the mode of mirror stabilization is deduced, and the dynamic equations of the system are deduced. The system of ADAMS Kinetic model. The electromechanical simulation was carried out by using Matlab / Simulink, and the influence of the strip on the stability accuracy under different stiffness and preload force was analyzed and obtained. The results provide the basis for the design of inertial stability platform.
