Research on the Control Strategy of Tire Cavity Resonance Noise in Vehicle

Tire cavity resonance noise is vehicle interior noise caused by tire cavity resonance, which can be clearly felt by passengers inside the vehicle when driving at high speeds on flat road or at low speeds over bumps. This article analyzes the mechanism of the tire cavity resonance noise and proposes control strategies for tires, wheels, and suspension systems. Based on the problem of excessive tire cavity resonance noise in a certain vehicle, a problem analysis was conducted based on the control strategy proposed in this article. The identified reason was the coupling resonance between the rear suspension mode and the tire cavity mode, which caused the vibration generated by the tire cavity resonance to be amplified during the transfer to the vehicle body. The tire cavity resonance noise was reduced significantly by installing a dynamic damper on the rear suspension of the vehicle.
