Simulation and Analysis of Induction Noise in Commercial Vehicles Coupled with Air Compressor
In order to predict the induction noise of commercial vehicles,a new 1-D simulation model of air compressor is proposed.The Compressor-Engine coupling simulation model can predict the frequency and amplitude of the noise at the main order accurately,and can both recognize the order noise from the air compressor and the engine in the meantime.The characteristic of compressor noise and the noise reduction method of compressor path are studied by this coupling model.The results show that the noise of the compressor has typical pulse noise characteristic.When dealing with this type of noise,the arrangement sequence of different types of mufflers will have a significant impact on the noise reduction effect.
