象鼻式铣齿机立柱的优化设计

Optimization Design of Nasal Type Gear Milling Machine Column

机床结构刚度的提高有助于提升机床加工精度及改善机床的动力学性能。基于结构仿生学,利用拓扑原理对象鼻式铣齿机立柱内部的筋板结构进行优化设计。对原型及改进后的立柱进行了静力、模态分析。结果表明,改进后的立柱质量减轻,刚度性能及力学性能得到明显提高。

High stiffness of machine tool structure helps to improve the machining accuracy and the dynamic performance of machine tools. Based on the bionic structure, the theory of topology is used to optimize the stiffened plate structure design of the nasal type gear milling machine tool column which is made play the role of the skeleton. Through the static modal and finite element analysis of the prototypes and bionic column, it is found that the mass of the column is reduced and the quality of the specific stiffness structural efficiency and its static-dynamic performance are improved greatly.
