基于CAE技术的两阶段结构优化设计方法

Two Phases Construction Optimization Design Method Basing on the CAE Technique

利用 CAE技术 ,对一受集中荷载作用的矩形板依次进行拓扑设计和尺寸优化的计算与分析 ,最后得到给定条件下的合理结构。研究结果表明 ,拓扑优化与尺寸优化相结合的结构系统优化设计方法 ,是解决具有较少目标的结构优化问题的一种有效方法。

With the help of CAE tool, this paper, in turn, proceed to the topology optimization and size optimization to a rectangle plate bearing the focus load, and finally getting the reasonable structure under given conditions. The research result shows that the system optimization method with topology optimization and size optimization is a valid try to the construction optimization problem.
