Based by controlling the orderly changes of the PZT moving mechanism and positive pressure between supporting faces in mechanical way
a novel kind of inertial piezoelectric rotary actuator is proposed. Structure models of the rotary actuator is designed
the moving principle is analyzed
the prototype of new inertial piezoelectric rotary actuator is designed and manufactured
the performance of the actuator is tested,the dynamic formulation of inertial actuator is established
by using matlab software
the kinetic simulation of the actuator is carried out
the displacement and speed simulation curve of the actuator is conducted
the structure of newly 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。
