摘要: 为研究满足轻量化、高阻尼使用要求的Fe/碳纤维增强聚合物(CFRP)混合结构机床构件,本文运用引入约束因子的变密度法对原型铸铁横梁进行了三维结构拓扑优化,对其铺设CFRP自由阻尼层以提高阻尼特性。基于响应面法建立了关键铺层参数对结构最大变形与阻尼损耗因子的回归方程,并对铺层参数与横梁性能进行分析,通过遗传算法对复合横梁铺层参数全局寻优。结果表明:铺层角度为46.03°、0°铺层铺设比例为25.39%、铺层顺序为C2时,Fe/CFRP混合结构横梁综合性能最优,其刚度基本保持不变,重量减轻35.7%,阻尼性能提升62.7%,试验结果与仿真结果一致。

Abstract: In order to study the Fe/CFRP (carbon fiber reinforced polymer) hybrid structure machine tool components that met the requirements of lightweight and high damping, in this paper, the three-dimensional structural topology optimization of integral metal beam was carried out by using the variable density method with constraint factors, and the damping characteristics are improved by laying CFRP free damping layer. Based on the response surface method, the regression equation of key pavement parameters on structural maximum deformation and damping loss factor was established, and the pavement parameters and beam performance were analyzed. Genetic algorithm was used to optimize the layer parameters of composite beam globally. The results showed that when the laying-angle was 46.03°,the 0° laying-thickness ratio was 25.39% and the laying-order was C2,the composite performance of Fe/CFRP hybrid milling machine is best, and its stiffness was unchanged. The weight was reduced by 35.7%, and the damping performance was improved by 62.7%, the experimental results are consistent with the simulation results.
