基于 ESO 和 BESO 连续体结构拓扑优化分析

摘要

使用 APDL 参数化设计语言编写程序，利用 ANSYS 软件平台实现了对大型龙门工程机械横梁的拓扑优化。分析结果表明，双向渐进结构优化算法（BESO）迭代过程快，计算效率高，优化结构清晰。%In this paper,writing programs by ansys parametric design language (APDL),and u-sing ANSYS software platform we completed the topology optimization process of large scale pro-ject machinery beam gantry.The results show that,BESO algorithm has advantages of fast itera-tive process,high computational efficiency and clear optimize structure.
