摘　　要：在对驱动器机械结构进行设计分析的基础上,建立了以压电叠堆为驱动元件的精密旋转驱动的数学模型,并对所设计的驱动器样机从旋转运动分辨率、运动稳定性、旋转速度及承载等方面进行了实验测试。测试结果表明,所开发的驱动器样机旋转速度可达2990.6μrad/s、输出扭矩0.147 N.m、最小旋转步距(旋转分辨率)小于0.32μrad,运动行程为连续360°,驱动器性能稳定可靠。Based on the construction analysis of the mechanical structure of the rotary actuator, a mathematical model was built for the precision rotary actuator with the PZT stack as actuating element. The developed actuator prototype was tested and its angular resolution, rotating stability, rotating speed and carrying capability were measured. The results showed that the actuator prototype works stably and reliably, its rotating speed can reach 2990.6μrad/s, the torque output is 0. 147 N·m, the minimum stepping angle （ angular resolution） is less than 0. 32μrad, and the rotor can rotate around the axis for 360° continuously.
