基于非对称夹持的压电旋转驱动器设计
Design of Piezoelectric Rotary Actuator Based on Asymmetric Clamping Mechanism
摘要
Abstract
A novel piezoelectric inertial rotary actuator was presented herein based on asymmetric clamping mechanism.The actuator can achieve unidirectional rotation movement by the reciprocating swing of the masses to produce asymmetric inertial impact force when the piezoelectric bimorph pasted on the substrate was applied to the symmetric electrical signals.A prototype was fabricated and a seG ries of experiments were conducted to evaluate its performance in terms of angular displacement,fricG tion torque,and load characteristics.The results show that the angular displacement resolution of 1 . 82μrad is obtained by applied square wave of 15 V,frequency of 10 Hz under the clamping difference of 3 mm and maximum output load is 0.122 N under the friction torque of 2.475 N�mm.关键词
