Research of Aerodynamic Noise Prediction of High-Speed Train

Abstract:

Under the background of China rapid development of high-speed train, this paper aims at prediction of the aerodynamic noise of train, which plays a key factor for controlling the train noise. In order to develop the prediction model of the aerodynamic noise of train, first the finite and boundary element theory are utilized to calculate the fluctuation pressure of the motion train; then Statistical Energy Analysis (SEA) model of the train noise is built and the SEA parameters are calculated. Based on the above models, the prediction method of aerodynamic noise of train is developed to calculate the train noise with train velocity.
