摘要

This study presents the design and model of a XY parallel inertial drive mechanism (PIDM) based on piezoelectric bending actuators. Mechanical structure of the PIDM and its working principle are introduced. A dynamic model of the XY PIDM is established with simplification of mechanism and expansion of friction force. With extracted dynamic model parameters, numerical simulations of the XY parallel motions are implemented using software MATLAB/Simulink. Stepping responses of the single DOF motions and cooperative planar motions with various driving parameters are analyzed.
