| 摘 要： | 对五轴联动加工中心主轴系统进行动力学仿真分析,对原主轴系统的轴承支承系统和主轴结构进行了动态优化设计.针对主轴前端的单排轴承的不足,提出了双排轴承的设计方案.对于主轴结构,论文建立了以主轴前端动态变形最小为目标函数的优化模型,对主轴结构进行了优化设计,从而提高了主轴系统的静力学和动力学特性,满足了设计要求.

| Abstract: | Base on the dynamic simulation of the spindle system of 5-axis machining center, dynamic optimization design is done about the bearing support system and the structure of the spindle. To overcome the disadvantages of one-support bearing, two-support bearing is applied to the fore part of spindle. The minimum displacement of the spindle nose is used as objective function to design the structure of spindle. By these ways, the statics and dynamics characteristic of the spindle system are improved and satisfy the design demands. |
