基于粘滑驱动原理的压电式直线-旋转运动平台
Piezoelectric linear-rotary motion stage based on stick-slip driving principle
摘要
Abstract
A linear-rotary piezoelectric motion platform based on the stick-slip driving principle was devel-oped to address the requirements of robot-assisted target puncture.The platform integrates a two-degree-of-freedom flexure mechanism with an active locking flexure mechanism to achieve coupled linear-rotary motion while effectively suppressing backward displacement.Statics were derived using the compliance matrix method and a closed-loop serial flexure model,and structural parameters were optimized via a ge-netic algorithm.Static,modal,and transient response analyses were conducted using finite element analy-sis to determine the optimized amplification ratios and to validate the effectiveness of the active locking mechanism.Experimental results indicate amplification ratios of 2.865 and 1.568 for linear and rotary mo-tions,respectively.The active locking mechanism reduced linear and rotary retraction displacements by 69.15%and 89.40%.The actuator attained a maximum linear velocity of 2 428.25 μm/s with a resolu-tion of 0.569 μm.In the rotary direction,continuous 360° rotation was achieved with a maximum speed of 58 019 μrad/s and a resolution of 14.4 μrad.The actuator exhibited low coupling between motions and high bidirectional motion consistency(≥94%),demonstrating suitability for target-puncture applications.关键词
