Optimum Structural Design of Some Anchor Windlass Frame

结合有限元法、拓扑优化理论以及尺寸优化理论,对某锚机机架进行了系统的创新设计。首先根据锚机设计参数确定该机架的基本尺寸和材料参数,以此建立机架有限元模型,并在此基础上建立拓扑优化模型,得出该机架的最佳传力路径;再根据优化结果建立了三种设计方案的壳单元数值模型和相应的包含离散变量的尺寸优化模型,进行机架的详细设计和比较分析,得出最优机架结构。

A creative design of some anchor windlass frame is presented in the paper, combining the finite element method, the topology optimization and the size optimization theories. The basic dimensions and material parameters are obtained firstly, according to the anchor design parameters. Secondly, the finite element model and the topology optimization model are established, based on which the best load transfer path is gained Finally, shell element numerical models and their size optimization model for the three designing schemes are presented, and the detail design and comparison for the frame are carried out to obtain the optimum frame.
