摘　　要：提出通过机械方式控制压电驱动机构和支撑面之间正压力的有序变化,形成有规律的新型惯性压电驱动机构的研究方案。分析了机构的运动机理,建立了机构的动力学模型,应用现代控制理论,利用Matlab对机构进行运动学仿真,得到了机构位移仿真曲线,设计、制作了驱动机构样机,并作了相关的性能测试。仿真计算和试验结果表明了运动机理和动力学模型的正确性。By controlling the orderly changes of the PZT moving mechanism and positive pressure between supporting faces in mechanical way, a novel inertial piezoelectric actuator is proposed. Working principle of the actuator is analyzed, and the dynamic formulation of inertial actuator is established. Using matlab software, the kinetic simulation of the actuator is carried out, and the displacement simulation curve of the actuator is conducted. The structure of novel inertial actuator is designed and manufactured. The motion theory and dynamic formulation of the actuator are proved through comparing the results of simulation and experiment.
