干摩擦力 meaning in Chinese

dry friction

Firstly , under the assumption that the output driving torque generated by the stepper motor of the mirror is constant , such influence analysis is conducted . secondly , a mathematic model of the stepper motor is given . under the assumtion that the input impulse frequence is constant , the rotational motion of the stepper motor of the mirror with the mutual exertions of damping torque , friction torque and disturbance torque generated by satellite platform ' s attitude motion is simulated and analyzed
对卫星平台姿态振动对红外相机扫描机构转动的影响进行了系统深入的仿真分析:首先在步进电机驱动力矩一定条件下,仿真分析了星体姿态运动干扰力矩对红外相机扫描镜转动的影响;接着建立了步进电机的数学模型,在步进电机输入脉冲频率一定条件下,仿真分析了步进电机在阻尼力矩、干摩擦力矩、平台干扰力矩等负载转矩的共同作用下的转动情况。
