【Abstract】 Through establishing the Finite Element Model(FEM) of a novel linear motor and testing its prototype,a kind of method used in simulating the character of linear motors was obtained.By means of the method of the orthogonal experimental design and the random experimental design,the sample space of the character parameters of the linear motors was established,and by the nonlinear regression method of the Support Vector Machine(SVM),the nonlinear mathematic model of a novel linear motor was given.Comparing the FEM model with the SVM model in aspect of consistency and computing speed,the authenticity and effectiveness of the SVM model were confirmed.更多还原
