结构优化设计&有限元分析在机械设计中的应用——ABAQUS分析桁架结构

The application of the structure optimum design and the finite element method in the Mechanism design——using ABAQUS to analyze the truss structure

优化设计是一种寻找确定最优设计方案的技术。本文探讨了在有限元分析基础上对结构进行优化设计的理论和方法,结合ABAQUS软件,对其中的一些关键问题进行了研究。通过对一个桁架结构工程实例的优化设计计算,检验了该方法的效率,同时,还研究了影响桁架结构优化设计的主要因素。

Design of optimization is a technique that is used to determine an optimum design. Based on the finite element method, this paper discusses theory and method on design of optimization by means of ABAQUS. Truss structural example is used to examine the efficiency of the approach, and it can be used as a reference in the engineering design.
