Simulation model of maglev coupling dynamics performance based on SIMPACK

In order to effectively evaluate the dynamics performance of maglev, SIMPACK was introduced, a vehicle-track-control system coupling dynamics model was established according to the topological relationship chart of maglev kinematics, and a test example was presented to detailedly verify the model. In the model, vehicle was treated as a full dynamic rigid multi-body model with doubled suspension systems, Euler beam was utilized to model rails, and the control system of maglev was also taken into consideration. Comparison result shows that the maximum deformation of beam is 1.5 mm, while the test result is 1.6 mm; the vertical accelerations of carbody in simulation and test are reasonable. So the model is feasible to test and evaluate the dynamics characteristic of maglev in engineering application.
