基于Solidworks的磁悬浮导轨

摘要

随着微机电系统(MEMS)及纳米技术的发展，对精密工作台的位移精度和动态特性等提出越来越高的要求。这就要求作为精密工作台的重要组成部分的导轨具有较高的位移分辨率、定位精度以及动态特性。

本论文针对传统导轨直接接触的固态导轨面之间存在着不可避免的摩擦力导致忽跳忽停的爬行现象，研究一种导向性能优异的磁悬浮导轨。考虑到传统磁悬浮导轨采用的电磁和超导磁悬浮技术不适合用于微定位系统环境，设计采用永磁悬浮导轨。同时，为悬浮的动导轨施加各个方向可调约束力，保证动导轨稳定运行。对磁材料进行深入对比，选择合适的材料。在结构设计时进行了力学平衡优化设计。最后利用solidworks软件，将所设计的磁悬浮导轨做成三维模型。

Research on the Structure of Maglev Guideway

Based on Solidworks

Abstract

With the development of MEMS and nana technology, the demands of precision worktable on positioning precision and dynamic characteristic are even higher. This requires as an important part of precision worktable of guide rail has high displacement resolution, positioning accuracy and dynamic characteristics。

Since the inevitable friction force of solid state guide rail surface, traditional guide rail has the crawling phenomenon , that is,to jump or to stop. Thus a new magnetic suspension guide rail is studied with fine guidance acharacter. Since the technologies of traditional magnetic suspension guide rail and superconductivity magnetic suspension doesn’t fit the micro positioning system environment, the permanent maglev guide rail is designed. At the same time, each direction adjustable binding force is designed to achieve steady kinestate of the guide rail. A kind of appropriate material is chose through contrast of several magnetism materials. The optimization design is carried on mechanical balance. Three-dimensional model of maglev guideway is made by Solidworks software finally.

Keywords: maglev guideway ,everlasting magnet, mechanics balance
