A new inchworm-type actuator with variable step and large displacement is presented.Dynamic model for piezoelectric actuator is built up,and the dynamic performance of the actuator is simulated by the MATLAB SIMULINK while the actuator working frequency is 30Hz.Experiment system with high voltage driver is designed,this actuator is composed of three parts: the clamping structure,the pushing structure and the tuning structure.This actuator can provide ± 8mm displacement,and the results of experiment are in good agreement with that of the Simulation in 0.1 μm accuracy demanded.
