摘　　要：为了避免空心轴电动机的电磁干扰,本文设计了一种仿真转台内框专用的大直径中空电液伺服马达;介绍了大直径中空电液伺服马达的工作原理和设计难点;马达采用特殊的轴肩式结构提高转轴的抗变形能力;前馈与PID控制方法被用于马达的伺服控制。地面实验表明该马达具有良好的抗变形能力、稳定的低速性能和很高的定位精度。To avoid the electromagnetic interference of electro serve motors, this paper presented a large-diameter hollow-shaft electro-hydraulic servo actuator for flight motion simulator inner girrbal＇s motion driving. The motor＇s working principle and design difficulties were introduced.A special structure was adopted to ensure the high non-deformability of the hollow shaft. PID plus feed forward control algorithm was used for the actuator motion control. Experiment results show that the rotary actuator has enough non-deformability, stable low-speed performance and high positioning accuracy.
