A study on the dynamic modeling of a magnetic levitation vehicle

There is growing in interest in the modeling and simulation of the dynamic behavior of advanced vehicles, including maglev-type systems. This paper demonstrates the application of DADS, a program especially suited for the analysis of multibody mechanical systems, to the dynamic modeling and simulation of a maglev system. A brief description is made of the modeling requirements of magnetically levitated systems along with a summary of some of the related capabilities of DADS. As a case study, an analysis of a vehicle based on the UTM01 system is presented. This paper shows that the presented modeling technique is applicable to the dynamic characteristics evaluation and control-law design of maglev-type vehicles.
