Research on Air Suspension System Based on Trackless Train

In order to improve the comfort of passengers when riding on trackless trains, it is necessary to set up an air suspension system for the train. In this research, the air suspension system is composed of sensors, height valves, ECAS solenoid valves, control ECU, and other mechanisms on the vehicle, so as to realize the adjustment of the height, softness, and vibration isolation rate of the suspension of the vehicle.
