Halbach型永磁吸附机构的有限元分析及优化
Finite element analysis and optimization for Halbach array-based permanent magnetic adhesion devices
摘要
Abstract
A novel permanent magnetic adhesion device based on Halbach array was designed and studied to utilize the advantage of one-side magnetic field characteristics of Halbach arrays to improve the magnetic adhesion performance of Halbach permanent magnetic adhesion devices and reduce their weight.The two dimensional mathematic model for the magnetic field of the permanent magnetic adhesion device was established by using the finite element method,and the finite element calculation expressions of the magnetic flux density and the magnetic force were derived.The influences of configuration parameters on the magnetic adhesion performance were analysed by using the parameter variation method.The optimization of configuration parameters of the device was done by using genetic algorithms,and the results and their correctness were proved by the magnetic force measurement.关键词
