Abstract:

A method of multi-objective optimization based on response surface method driven by the magnetic force after magnetization and demagnetization of the electro-permanent magnetic chuck and the consumption of materials is proposed in this paper. In this method, some key parameters of the electro-permanent magnetic chuck model are selected as design variables to establish the response surface model, candidate points are designed by goal driven optimization, and the parameters of the design variables which are in line with the anticipated goals are found in the candidate points. Using this method to optimize the electro-permanent magnetic chuck, the magnetic force when magnetizing increases by 35.7%, and the magnetic force when demagnetizing is reduced by 92%, the performance has been significantly improved, while optimizing the use of materials and improving the cost-effectiveness of the product.

Key words: response surface method, electro-permanent magnetic chuck, multi-objective optimization
