Anti roll decoupling mechanism is the key component of mid-low speed maglev vehicle bogies. According to the structural characteristics of maglev vehicle bogies, a new cross anti-roll decoupling mechanism was proposed, and dynamic simulation analysis was carried out based on virtual prototyping technology. The simulation results show that the anti-roll decoupling mechanism not only has simple structure, but also has better performance than the traditional anti-roll decoupling mechanism, which is fully applicable to the requirements of maglev vehicle, and solves the coupling and restriction problems between anti-roll and decoupling.
