| Abstract: | This paper utilizes the CFD method on the streamline high-speed train on open-wire to predict the location and strength of acoustic sound sources,and analyze the causation of the acoustic sound sources on different parts of the train after computation results are analyzed.Initiative design method is used to control the noise environment pollution in the initial stages of high-speed train design. |
