| 摘 要： | 以大型有限元通用软件ANSYS作为平台进行二次开发,探索基于渐进结构优化方法的结构拓扑优化途径.通过直接删除单元和运用单元生死技术,发展了两种实现结构拓扑优化的途径,并与ANSYS自带的结构拓扑优化功能进行比较研究.结果表明,直接删除法和单元生死法均可用于工程实际,运用单元生死技术进行基于ESO的结构拓扑优化有更大的灵活性和实用性.

| Abstract: | Based on second development of ANSYS,authors explore topology optimization methods based on ESO.Two methods of structural topology optimization are developed,i.e.element deleted method and element killed method.By comparing with topology optimization module of ANSYS,the results show that element deleted method and element killed method can be applied in engineering practice,and structural topology optimization based on element killed method has more flexibility and adaptability. |
