Abstract
The noise created by a vehicle rotor is reduced by adjusting the natural or resonant frequency at which the rotor tends to vibrate. The resonant frequency is moved away from the frequencies of excitation of such sources as the brake pads and vehicle drive train components. The resonant frequency of the rotor is adjusted by manipulating the geometry and mass of the rotor by adjusting the number, size, shape, spacing and location of cooling vents formed in the hat section of the rotor. The resulting rotor exhibits improved vibrational control.
