The FEM(Finite Element Method) model of a novel linear motor was established,and then its correction was proofed.To obtain sample space used to establish the nonlinear regression model,the FEM simulation tests were arranged with the methods of orthogonal and random experimental design.Moreover,the nonlinear mathematical model of a novel linear motor was established using nonlinear regression method of the Support Vector Machine(SVM).Then the optimum structure parameters was obtained by optimizing the structure parameters with Genetic Algorithms(GA).At last,the FEM simulating results show that the parameter optimization method based on SVM and GA is feasible for researching the new cylinder type linear motor.
