Abstract:



This paper presents a three-degree-of-freedom model of a section of the magnetically levitated train MagLev. The MagLev system dealt with in this article utilizes electromagnetic levitation. Each MagLev vehicle section is viewed as two separate parts, namely a body and a chassis, coupled by a set of springs and dampers. The MagLev model includes the propulsion, the guidance and the levitation systems. The equations of motion are developed. A Simulink simulation framework is implemented in order to study the interaction between the different systems and the dynamics of a MagLev vehicle. The simulation framework will eventually serve as a tool to assist the design and development of the MagLev system in the United States of America.

Description:




FLUX is a CAE software package for electromagnetic design, which utilizes finite element (FEM) analysis. FLUX includes full geometry parameterization capabilities, static and dynamic excitation capabilities, connection to internal or external electrical circuits, and linear and rotating motion capabilities. FLUX technology enables you to explore, evaluate, and understand the behavior of a device that contains nonlinear steel components, electric currents in conductors, and/or permanent magnets.





FLUX can be used in the research, design, and production of every type of electric device and process, from small appliances to large machinery, from audio speakers, to medical MRI. Coupled with other programs, FLUX solutions expand into drive technology, fluid power, mechanics, acoustics, and thermal analysis. FLUX offers a direct link to Simulink, enabling you to develop your control strategy directly in Simulink with the FEM model described in FLUX. During the computation, FLUX and Simulink are run in transient cosimulation.
