The dynamic response of a magnetic levitation (maglev) transportation system has important consequences for guideway design and system costs. The objective of this research is to develop a framework to analyze the dynamic interaction between a flexible guideway structure and a maglev vehicle named Electric Cargo Conveyor (ECCO). Different from other maglev vehicles, which use either electromagnetic or electrodynamic suspension technologies, the ECCO is the only system utilizing the Inductrack levitation technology, where the permanent magnets are arranged as so-called Halbach arrays to create a levitating force. The theoretical dynamic model of the ECCO system is derived in this paper. The guideway structure is modeled as a simply supported beam based on Bernoulli-Euler beam theory. The vehicle is modeled as a two-degree-of-freedom mass-damper-spring system. They are coupled with each other through nonlinear magnetic forces. To investigate the dynamic interaction between the vehicle and guideway, a finite element model of the ECCO system is created in COMSOL Multiphysics using its equation-based modeling interface. Numerical simulations are conducted to examine the effects of different factors such as the cargo weight and the vehicle speed.
