摘要
利用双向渐进结构优化法研究了装载机动臂结构的拓扑优化问题。利用有限元软件ANSYS的APDL语言进行二次开发,实现了多工况下基于应力水平的双向渐进结构优化法(BESO)。对装载机工作装置的动臂进行多工况下的结构双向渐进拓扑优化,得到了动臂的最佳拓扑结构。结果表明了该方法的实用性和有效性,且比ESO方法具有更高的效率。
The topological optimization on arm of loader is studied by the method of bi-directional evolutionary structural optimization (BESO). In this paper, based on stresses under multiple loads BESO is achieved by secondary development of ANSYS and using the APDL. Finally the arm of loader is analyzed by BESO under multiple loads and the results show that the method is efficient and practicable. The method has higher efficiency than ESO method.
