| 摘 要： | 应用ICM方法建立了悬臂式刮板取料机输送链板的拓扑优化模型,针对多工况应力约束下连续体拓扑优化中出现的载荷病态现象,提出了在优化过程中对载荷进行分层放大处理的策略.将ANSYS中单元生死法与ICM方法及分层优化过程有机结合起来,实现单元的删除、保留与复活.借助ANSYS软件平台,利用APDL语言实现了对输送链板的拓扑优化,完成了对输送链板的轻量化设计.

| Abstract: | The ICM method is used to build topological optimization model for conveyor link plate of cantilever strickle reclaimer.A multiple-level and load magnification strategy was introduced to solve ill loading problem, which often occurs in topological optimization with stress constraint for continuum structure in multiple loads. Element’s live and death method in ANSYS software associated with ICM method and multiple-level strategy are used to kill,reserve and resurge element.At last,topological optimization for conveyor link plate was accomplished,and light weight design was achieved through APDL in ANSYS. |
