Design and Analysis of a New Type of Spatial Flexible Micromanipulation Platform

摘要

A novel type of spatial flexible micromanipulator is designed based on flexure hinges, which can realize the translational motion along the Z axis and rotations around X and Y axes. During the design, we use the bridge displacement amplifier as translational pairs to drive platform movement, with a flexure hinges instead of the traditional hinges. The magnification ratio of the bridge displacement amplifier is calculated by the method of the elastic analysis with consideration of rotational and translational stiffness. The simulation and analysis are carried out with ANSYS Workbench. The theoretical calculation and simulation error are 8.77%. The micro-operation platform is analyzed by static simulation and modal analysis. The results show that the micromanipulator has a large working space and strong anti - interference ability, with a fast dynamic response speed.
