摘要：

This paper presents the design and analysis of a new large-range micro-gripper which is constructed using flexure hinges. The gripper is actuated by only one piezoelectric stack actuator ( PSA) and the output of the grip arm is approximately rectilinear movement, because the displacement of nonworking direction is extremely small. In order to achieve a large gripping range, a dual-stage amplifier is designed to magnify the stroke of PSA actuator. Analytical models are developed to facilitate the parametric design of the gripper structure. Finite-element analysis simulation is carried out to verify the gripper performance. A prototype gripper is developed for experimental testing. Experimental results show that the maximum output displacement of the device is 365.2 micrometers for one gripper tip under 100 V driving voltage.
