数控内圆磨床部件动态优化设计研究

机床部件结构动态优化设计是实现整机优化的基础.利用灵敏度分析技术优化了磨床部件内部筋板结构参数、布局参数,建立了磨床主轴系统结构的BP神经网络模型.并与实测结果比较,对模型进行修正,再利用修正后的模型对主轴结构参数进行优化.这些技术为磨床整机的优化奠定了基础,对相关机床动态优化设计具有普遍的指导意义.

Research on Structural Dynamic Optimal Design of NC Internal Grinder

Structural dynamics optimal design of key components is the basis of optimal design of the whole machine tool. The method of sensitivity analysis is applied to optimize the arrangement shapes and parameters of the strengthened bars of components. The BP neural networks model of the spindle system is established and corrected through comparing it with the experimental result, thus the structure parameters of the spindle are optimized. These technologies will benefit to realize optimal design of whole NC internal grinder and guide dynamic optimal design of other machine tools.chonStructuralDytorealizeoptimald
