Abstract
In automotive industry, the interior quietness is a task that manufacturers are constantly improving for passenger comfort. In order to improve the interior quietness there are considered the contribution of structure borne and airborne noise. An alternator used in vehicles for generation of electricity can be considered as a contributor of airborne noise. Due to the characteristics of an alternator, it could radiate mechanical, aerodynamic and electromagnetic noise. The last two characteristics are normally perceived by customer during powertrain and idle evaluation.
In this paper is presented correlation between interior noise measured on road test and alternator radiated noise measured on bench test.
