Abstract
This research introduces an experimental method and a theoretical analysis for the solution of automotive radiator cooling fan whine noise, and provides the optimization direction for resolving fan whine problems. The analysis of the whine root cause is put forward and validated by the modal tests with non-contact laser scanning vibrometry, in which the white noise signal is used to the fan motor as the excitation source. The results of the analysis and tests show the whine noise is mainly caused by the multiple resonances coincidentally between the excitations of the fan motor’s electromagnetic force and the vibration modes of the fan assembly simultaneously. So that to eliminate or reduce the harmonic excitation (magnetic field) from the rotor grooves will reduce the fan whine noise level significantly.
