摘要
文章利用有限元方法,借助Ansys workbench 14.0,以减重为优化目标,在保证结构具有足够强度和刚度的基础上,对原有某折弯机结构分别进行了尺寸优化和拓扑优化,给出了结构的优化模型。同时,对结构中不满足强度和刚度要求的部位进行了改进。尺寸优化后,滑块的最大位移降低19%,最大等效应力降低44%;机架的危险部位最大等效应力降低56%,机架的质量降低了12.7%。拓扑优化后,机架的质量减轻了19.1%。折弯机的综合性能得到大幅提升。
Using the finite element method,with the help of Ansys workbench 14,the weight loss as the optimization objective,the structure has enough strength and stiffness,the size optimization and topology optimization of original structure of a bending machine is performed,the optimization model of structure is given.At the same time,the structure does not meet the requirements of strength and rigidity of the parts was improved. After size optimization,the maximum displacement of the slider reduce by 19%,the maximum equivalent stress is reduced by 44%. The the maximum equivalent stress of dangerous part of the frame is reduced by 56%,the quality is reduced by 12. 7%. After topology optimization,the quality of frame reduced by 9. 1%. The comprehensive performance of bending machine has increased substantially.
