摘要

提出了通过控制正压力来改变摩擦力的方案，进而研制了一种以压电叠堆为动力转换元件的新型压电旋转驱动器。采用两个驱动用压电叠堆对称布置的方式设计了该旋转驱动器结构

探讨了旋转驱动器运动机理，制作了压电旋转驱动器试验样机并对其进行了试验测试。试验结果表明，该驱动器输出步长线性度较好，当驱动电压为10 V、频率为2 Hz时，驱动器旋转步长为20 rad。分析了驱动器输出稳定性，针对存在的问题提出通过施加控制系统来有效提高不同起始位置驱动器的运动稳定性。对试验结果进行误差分析，找出了产生误差的原因，为驱动器的进一步优化设计提供了参考。研究证明了该压电旋转驱动器设计方法的可行性，利用该方法可以制作出结构简单，体积小，适合在微驱动领域中应用的驱动器。

Abstract

A new piezoelectric inertial rotary actuator with piezoelectric stack as the power converter is proposed based on controlling the normal pressure to regulate the friction which hinders the movement of the actuator. Prototype and motion mechanism of this actuator characterized by two symmetric piezoelectric stacks are presented. Motion performance test of the prototype demonstrates that the actuator is excellent in A new piezoelectric inertial rotary actuator by taking piezoelectric stacks as the power converters was proposed based on controlling the normal pressure to regulate the frictional force. By arranging two piezoelectric stacks symmetrically

the structure of the piezoelectric rotary actuator was designed

and its motion mechanism was explored. A prototype of piezoelectric rotary actuator was developed and the experimental test on the actuator was performed. Experimental results show that the actuator is excellent in linearity of output step and its rotation step is 20 rad when the square wave is 10 V and the frequency is 2 Hz. The stability of the actuator was analyzed and an extra control system was added to overcome the shortcoming in the step stability at different start points. The error sources were obtained by analysis on the test data

which provides references for further optimization of the actuator. Research in this paper proves the feasibility of the design method for piezoelectric rotary actuators. It can be used in design of piezoelectric rotary actuators with simple structures

small volumes for micro-driving applications.
