Research on Simulation Method of EMU Air Whistle Sound

The sound of EMU air whistle is an important auditory signal to ensure safety and efficient operation of railway. The railway industry standards strictly stipulate various parameters of air whistle for locomotives and EMU, but sound insulation of shroud reduce the sound pressure level of ex-ternal sound field. In order to ensure that air whistle can transmit signals safely and effectively, it is very important to accurately simulate the sounding process of it. Based on working principle of
