An Optimized Design Method for Thickness of Shells with Multi-Holes Based on Finite Element Method Theory

Abstract:

Focus on the problems in thickness design of shells with multi-holes, an optimized design method based on theory of finite element method is presented. In this method, mathematical model of optimized design is built up based on theory of finite element method and theory of plates and shells, and realized method of optimized design of thickness based on ANSYS software is established. Additionally, the influence factors of optimized design of thickness are analyzed, including load forms, constraint types. In the end, an example about cellular board design shows this method is a good way and available in engineering projects.
