Design and Analysis of a Micro-Motion Platform Based on Flexible Mechanism

Abstract:

Piezoelectric materials is a kind of the most common smart materials whose geometric shape can be related to an energy input in the form of electric field. In the application of active materials to electromechanical energy conversion, electrical energy may be input to the material and the resulting deformation of the material can be used to move a load. In this paper, a micro-motion platform is designed based straight circular flexure hinge and driven through piezoelectric ceramic stack. The calculation formula of the natural frequency of the new micro-motion platform structure is derived. From the analysis, the deformation and stress of it are all under allowed value of 65Mn. The results indicate that, the micro-motion platform all are satisfy the need of design.
