Abstract:In order to study the noise control technology of turbocharger, the operating principle of turbocharger is analyzed, the generation mechanism of aerodynamic noises, which includes Whoosh noise, surge noise, blade tone noise, buzz-saw noise, blade tip clearance noise, etc, and structure noises, which includes bearing system noise and Rattle noise, etc, are explained. The research review of control technology on Whoosh noise of turbocharger both domestic and overseas is described in detail, and the noise control technology of turbocharger is comprehensively analyzed. Based on above result, the development trend of noise control technology of turbocharger is pointed out.

Keywords:turbocharger; noise; generation mechanism; control; development trend
