| Abstract: | In order to study the characteristics of tire cavity resonance noise and its evaluation methods,by inflating air and helium to inside the tire and pasting the non-sound-absorbing foam and different sound absorbing materials in the inner liner,an experimental study on the correlations between the characteristics of tire force transmission rate and that of cavity resonance,including tire drop noise,indoor noise on dynamometer and real vehicle road noise,are carried out.The results show that both helium filling and porous sound-absorbing material have apparent effects on the tire force transmission characteristics and the tire cavity resonance noise.Tire drop noise and indoor noise on dynamometer can effectively reflect the tire cavity resonance characteristics.The tire force transmission rate peak is well consistent with the tire cavity resonance noise peak.Accordingly it is concluded that the tire cavity resonance noise can be characterized by the tire force transmission rate. |
