- Abstract
In order to reflect the vertical random vibration characteristics of railway vehicles more truly and effectively, this paper regards the human body as a single-degree-of-freedom system attached to the bottom of the carriage, and establishes a vertical dynamic model of railway vehicles by considering the influence of the coupling vibration effect between the passenger and the car body. The correctness of the model is verified by the real vehicle test. Then, the influence of the passengers on the vertical vibration characteristics of railway vehicles is analyzed, and the influence of the railway vehicle vibration on the vertical vibration characteristics of passengers is discussed in this paper. The research made in this paper can provide an effective model reference for the analysis of the vertical random vibration characteristics of railway vehicles and passengers, and for the optimization design of the suspension system parameters.
