An Experimental Study on the Vibration of the Low-Speed Maglev Train Moving on the Guideway with Sag Vertical Curves

Abstract

The low-speed maglev transportation technology is becoming a new type of urban rail transit. The vibration of the train is the crucial point for comfort and performance of the new type transit. The trial operation of the low-speed maglev train shows that a strong vibration of the vehicle may occur when the vehicle moves on the rail with sag vertical curves. In order to analyze and prevent this problem, a multi-sensor low-speed maglev vehicle experimental platform is established. The vibration signals are collected, processed and analyzed by the experiment. We present that the spiral transition curve should be put into the rail to reduce the vibration. The experimental results are included to provide valuable reference for the design and construction of the low-speed maglev transportation line.
