Computational Analysis of a Miniature 3-DOF Flexure-Based Micro/Nano Mechanism

摘要：

　　The work presented in this paper focuses on the computational analysis of a miniature flexure-based mechanism.This novel flexure-based mechanism is capable of delivering planar motion with three degrees of freedom (3-DOF).With this computational study,we examine the stress distribution at all flexure joints,modal analysis and the workspace envelop of the mechanism.This mechanism is designed to use three piezoelectric actuators to achieve desired displacement in X,Y and Θ.The knowledge of mechanisms workspace envelop will be very important in path planning and defining motion trajectories.The computational analysis confirms the stress distribution at flexure hinges do not exceed the allowable stress of the material.Analysis of the workspace predicts maximum displacements of 76.7 μm in the X-direction,69.1 μm in the Y-direction and 3.47 mrad in θ- rotation.
