Research of the Vibration and Noise Controlling About the Automobile Exhaust Pipe

Abstract

When a car engine working in the condition of idle speed or running on the slope pavement or bumpy conditions, the vibration noise will emerge from the automobile exhaust Pipe, to reduce and eliminate such vibration and noise, data analysis and testing for Vibration source of exhaust pipe and tube sizes were made. We found the vibration and noise is caused by too large amplitude of vibration when the car engine working in condition of idle speed or the car body bumping. By changing the exhaust pipe size and other technical measures to reduce or eliminate vibration noise of the exhaust pipe.
