    Abstract:

    Based on the structural characteristics of vehicles， a dynamical model of suspension frame and suspension magnet chain structure of electromagnetic suspension （EMS） high-speed maglev vehicle was established， and the suspension control algorithm based on state observer was introduced to simulate the active suspension control. Combining with the finite element model reflecting the unique structural and dynamical characteristics of maglev turnout， a numerical analysis model of maglev vehicle-turnout system was established. It is shown that simulation results are close to the in-situ measurements. On this basis， the dynamic response analysis of vehicle-turnout in single- and multi-car formation at low， medium and high-speed running through the turnout was carried out. Both numerical and experimental results show that defining the parameter matching relation of the vehicle-turnout-suspension control system is the premise and key to reveal the interaction mechanism between the maglev vehicle and turnout.
