Abstract
Abstract
Tire cavity resonance noise (TCRN) is one of main contributors to vehicle interior noise which has been a concern in the automotive industry. As the wheel is the first part of TCRN energy propagating into the vehicle, the propagation characteristics of energy in the wheel are studied. Firstly, the finite element models of wheels (steel wheels and aluminum alloy wheels with the same type) are established, and the propagation characteristics of TCRN in steel wheels and aluminum alloy wheels are studied and compared by the power flow method. Then, the models of three aluminum alloy wheels with different spoke configurations are established, and the propagation characteristics of TCRN in different aluminum wheels are studied by the power flow method. TCRN is easier to propagate in Y-shaped wheels than in V-shaped and star-shaped wheels, while the TCRN propagation characteristics in V-shaped or star-shaped wheels are not significantly different. So the study of propagation characteristics can provide basis for aluminum alloy wheel spoke design.
