Maglev Transport Synchronous Motor Calculation And Simulation Software Design

The transportation is the base of the national economy. With the development of society and economy, we need much better transportation system. Our country's territory is vest, so we need more long transportation. As one of the greatest creations in the 20th century, MAGLEV (magnet levitation) high-speed transport system is suitable of our country because of its high speed, comfort, security and no pollution. Now we have constructed the MAGLEV system that is the first MAGLEV system applied for business in the world. This key technology of this system is introduced from Germany. One of the key technologies is long stator synchronous linear motor that is the driving device of the MAGLEV system. If we study it in depth, we can construct the MAGLEV system with ourselves early.The main content of this dissertation is as follows:First, this dissertation describes the basic theory and the development status of the linear motor and the MAGLEV system, calculates the electricity and magnetism parameters and the thrust by combining magnet circuit and magnet field.Second, this dissertation describes briefly basic theory of Finite Element Method (FEM) of motor magnetic field analysis and the software of ANSYS. And then expatiates the design method of calculation and simulation software of synchronized linear motor of MAGLEV, introduces the design tool of Visual Basic Language. Basic on these theory, this dissertation expatiates the method of how VB calls ANSYS in the software.Finally, this dissertation describes how to use ANSYS analyse the magnetic field of Long stator synchronized linear motor, calculate its thrush suspend force , inductance and induction voltage of generator. Analyse the relation between these parameters and the geometrical size of the motor. Basic the introduction of the design method of the software, this dissertation finish the secondary design of ANSYS basic on VB, designs the user-interface, make the parametric come true. This dissertation introduces the main interface and menu of the software, expatiates the step of magnetic field analysis, and finally take some example to illustrate it.
