Research On Five Degree Of Freedom Relationship Between Magnetic And Track For Suspension Electromagnet Of Maglev Train

The biggest difference between the maglev train and the ordinary wheel rail train is that the relationship between the rail and the wheel is replaced by the magnetic and track,which makes the train not directly contact with the track during the operation.The study of the relationship between magnetic and track is the key to the analysis of the dynamics of the maglev train,and the interaction between the suspension electromagnet and the rail is the basic reason for the vehicle track coupling.This paper focuses on the maglev train and studies the relationship between the five degree of freedom magnetic.The main contents are as follows:Established a three-dimensional finite element model of the suspension electromagnet Maxwell,and obtained the electromagnetic force and torque data near the equilibrium point by the full factorial experiment design.By using 3D Maxwell software,Completed the finite element model and solved the electromagnet force.The experimental data were analyzed by the response surface analysis method based on the Design-Expert software.Research on vertical electromagnetic force model.Analyzes and verifies the accuracy of the model by a numerical model of vertical electromagnetic force generated by response surface method.Analysis the coupling effect of various factors on the vertical force by combining with the three-dimensional response surface,and obtains the variation of the vertical force with different position factors.Obtained the vertical force values of the two methods by comparing by using single degree of freedom and comprehensive verification.The vertical force is calculated by the finite element method and the numerical model.Verified the accuracy of the model by the response surface method,and analyze.the error of the model.Research on lateral electromagnetic force and pitch electromagnetic torque.Using the response surface method,the transverse electromagnetic force and the numerical model of the pitch electromagnetic torque are generated,and the accuracy of the model is further analyzed and verified.The coupling effects of various factors on the lateral force and pitch moment are analyzed by combining the three dimensional response surface.Through comprehensive verification,the lateral force and pitch moment values of the two methods are compared with the finite element method and the numerical model,and the accuracy of the numerical model is verified by the method of response surface method,and the model error is analyzed.
