在航测仪器中电传动系统的主要要求有两点,①具有精确的传动精度;②具有快速的跟随速度。本文论述了选择最佳减速比的两种方法,以满足上述要求。即根据最小稳态误差和根据取得最大加速度的要求确定最佳减速比。文中给出了计算减速比的公式。
In aeronautics and astronaut equipment in the main requirements of the electric drive system has two points, ① with precise transmission accuracy; ② with fast follow speed. This article discusses two ways to choose the best reduction ratio to meet the above requirements. That is based on the minimum steady-state error and the maximum acceleration obtained according to the requirements to determine the optimal reduction ratio. The paper gives the formula to calculate the speed reduction ratio.
