| Abstract:The low-frequency noise of the timing belt of a three-cylinder turbocharged direct injection gasoline engine at idle speed was studied. The noise source and noise frequency spectrum were derived by test. The mechanism of noise generation was also analyzed. According to the obtained noise source and spectrum, the layout parameters of the timing belt system were optimized by the one-dimensional dynamic simulation. The method to reduce the noise was worked out and verified by noise vibration and harshness test. It is to increase the stiffness of the timing belt and add an idler. |
