碩士 === 國立交通大學 === 機械工程系所 === 95 === Because of low power consumption, ultra-high resolution and rapid response, piezoelectric actuator is one better choice of actuator for micro-stepping mechanism. Micro-stepping mechanism is an impact drive mechanism constructed by using the rapid displacement response of piezoelectric actuator and stick-slip motion of friction mechanism. A mass-damper-spring model is constructed to investigate the dynamics of the mechanism. The experiments are divided into two sections. We will combine the DSP controller and the laser interferometer measuring system to the experiment. To discuss the influences of different piezoelectric actuators and to identify the system of micro-stepping mechanism will help us to begin the next experiment. Next experiment is about the shift and rotation of 2-dimension micro-steeping. To find out the relations between the different waveforms and the displacement of the mechanism is the way to make the result close to the simulation and to achieve the purpose of precise positioning.
