摘要：
In order to study the influence of driving speed on road noise，the relationship between the rolling speed and the modal natural frequencies and vibration response of the elastic ring tire model is analyzed in details. The CDtire model of a SUV tire is established and verified by modal test. Then vibration frequency response in main directions of the CDtire wheel center at different rolling speeds is analyzed. The results show that comparing the two conditions of tire rolling at 40 and 60 km/h，the in-plane radial vibration response of the second order modal is bigger at 40km/h，with a higher road noise level of the former in corresponding frequency，which is verified in road noise test of real vehicles. © 2023 SAE-China.
