为了提高数控插齿机床身结构静刚度和动态性能,基于SIMP材料插值方法,采用折衷规划法,建立以刚度最大化和低阶模态频率最大化的多目标拓扑优化模型,对数控插齿机床身进行拓扑优化,得到最佳拓扑形式。根据拓扑形式重构床身模型,并对原结构模型和重构模型进行分析,结果表明,经过拓扑的结构能同时满足数控插齿机床身静刚度和振动低阶频率的要求,为数控插齿机床身结构拓扑优化设计提供一种方案。
In order to improve the static stiffness and dynamic performance of the CNC gear shaper machine bed structure, a multi-objective topology optimization model based on the SIMP material interpolation method and the maximization of stiffness and maximization of low-order modal frequencies is established by using the compromise programming method. Body topology optimization, get the best topology. According to the topology form, the bed model is reconstructed, and the original structure model and reconstruction model are analyzed. The results show that the topological structure can meet the requirements of NC gear machine tool’s static rigidity and vibration low-order frequency simultaneously, Machine bed structure topology optimization design provides a solution.
