Finite Element Analysis of Moving Platform Based on ANSYS Workbench

Abstract

The thickness and rib layout of the moving platform which is a part of 2-DOF motion platform is the main factor affecting the performance of it. This initial design scheme was analyzed by making the use of ANSYS Workbench, which controls the maximum deformation and maximum stress in the range of permission. The quality of the platform could be reduced by 35.4%; the lightweight analysis and the modal analysis were made for the platform, and had obtained inherent frequency of the platform. The holes with quadrilateral shape were adopted to ensure that the platform could have enough stiffness and stability.
