Abstract

Tire cavity noise is a noise produced in the cabin by resonance in the hollow cavity inside the tire when it is excited by unevenness on the road surface, and this phenomenon is one factor of road noise.A noise-reducing wheel was developed as a means of reducing tire cavity noise. In the proposed configuration, a thin, lightweight plastic Helmholtz resonator is fitted into grooves newly cut in the wheel well, balancing strength in relation to centrifugal force with fittability. The noise-reducing wheels have had the effect of reducing tire cavity noise to an inaudible level.The newly developed noise-reducing wheels are used on the 2011 model HONDA LEGEND / ACURA-RL, mass-market vehicles.
