Abstract

In this paper, the line test and vibration analysis of a straddle-type monorail vehicle are carried out. Firstly, the basic situation of the field tracking test is introduced, and then the vibration evaluation method is determined. Finally, the vibration response of the car body, the vibration response of the bogie and the Sperling index of the passenger compartment are studied through the data analysis of the line test. The research results show that the main frequency of the center frequency of 2.6Hz is the main reason for the large vertical Sperling index of the car body floor. And there are two main frequencies below 40Hz at the frame measuring points. The lateral and vertical Sperling indexes of the vehicle are quite different, and the maximum values of all vehicles vertical Sperling indexes are greater than 3.3, while the maximum values of vehicle lateral Sperling indexes are generally less than 2.5.
