| Abstract: | The noise sources are much different between a pure electric vehicle and an internal combustion engine vehicle due to their different internal structures.In this paper,using the testing data obtained by the vibration noise spectrum analyzer,the spectrum analysis of the different parts inside a pure electric vehicle body is carried out out through the spectrum analysis method.By comparing the spectrum characteristics of the main parts of the pure electric vehicle,the noise sources under different working con... |
