Ear Pressure Phenomenon and Its Solution to Low-frequency Noise Inside a Pure Electric Bus
This paper studies the ear pressure phenomenon of low-frequency noise in a pure electric city bus during its operation.Firstly,it determines the mechanism of ear pressure phenomenon through experimental testing and data analysis.Subsequently,it formulates an optimization scheme for the vehicle body structure based on CAE simulation.Finally,it shows that the optimization scheme is feasible and the ear pressure phenomenon is solved through the real vehicle verification.
