Design and Optimization of Permanent Magnet Chuck

Permanent magnetic chuck of wind power generation tower is taken as the research object in this paper. Aim-ing at the problems of long experiment period and hard calculation in the traditional magnetic circuit optimization pro-cess,a method with which better structure parameters can be selected in the given design space is offered. Firstly,the method of orthogonal experiments is adopted to ensure the compound modes of different simulated parameters to mini-mize the experiment numbers of the optimized parameters. Secondly, finite element simulation is fulfilled with ANSYS software. The adsorption force with selected parameters is determined and the influence of different magnetic circuit and dimension parameter on the permanent magnetic chuck is analyzed. Finally, the permanent magnetic chuck which has the largest adsorption force and meets the usage conditions in the given design space is gained according to the effect of different parameters on the permanent magnetic chuck. All the tests show that comprehensive application of the finite element computing method and the orthogonal experiments to select the design parameters can reduce the experiment times effectively,avoid calculation of complex formulas and get the best structure of permanent magnetic chuck quickly.
