When the maglev train with a speed of 600 km/h runs at high speeds, the vertical carriage vibrations caused by irregularity of tracks are intensified, affecting passenger comfort and even safety. Therefore, it is necessary to find new damping devices to reduce carriage vibrations. Magnetorheological fluid dampers have advantages such as continuously adjustable damping, low-power consumption, high damping force output, and fast response speed. This paper firstly discusses the feasibility of applying magnetorheological fluid dampers to the secondary suspension system of maglev vehicles. It investigates the working mode, installation position, and stroke of magnetorheological fluid dampers for high-speed maglev trains. Based on a simplified suspension model for maglev trains, a magnetorheological fluid damper control system based on fuzzy logic is designed. The effectiveness of the proposed semi-active secondary suspension system based on magnetorheological fluid dampers is verified through numerical simulations, demonstrating its ability to effectively improve the vibration reduction performance and ride comfort of maglev trains.
