- 构建多学科协同的迭代式设计流程，聚焦实际制造难点
- 实现高转速非接触运行，解决传统轴承摩擦与热膨胀问题
- 适合从事精密制造与高端装备研发的工程人员参考
微铣削主轴需要高转速运行，传统滚动轴承在摩擦和热膨胀方面存在局限。主动磁悬浮轴承（AMB）通过非接触、无润滑方式实现在超高速下的运行，并可主动调节主轴动态特性。现有文献多集中于特定原型或控制系统的实现，缺乏系统性设计知识积累。本文提出一种系统化、迭代式的设计与制造框架，涵盖多学科协同流程，重点解决实际制造中的关键问题。所实现的主轴作为案例进行报告。
原文摘要 · Abstract (English)
Micro-milling spindles require high rotational speeds where conventional rolling element bearings face limitations such as friction and thermal expansion. Active magnetic bearings (AMBs) address these challenges by providing non-contact and lubrication-free operation at ultra-high speeds with the ability to actively regulate spindle dynamics. The existing literature on AMB spindles has mainly reported specific prototype realizations or control system implementations for specific spindle dynamics. Consequently, design knowledge remains fragmented across isolated successful studies. This paper addresses this gap by presenting a systematic and iterative framework to design and manufacture a micro-milling AMB spindle. The process involves a multidisciplinary design flow with a focus on critical practical aspects of manufacturing. The realized spindle is reported as a case study.
