摘　　要：为研究轮胎空腔共振噪声特性及其评价方法,通过在轮胎内部充入空气与氦气,在内衬层粘贴不吸音泡沫和不同的吸音材料,对轮胎的力传递率特性与轮胎跌落噪声、室内转鼓噪声和实车道路噪声等空腔共振特性之间的关联关系进行试验研究。结果表明:轮胎内充入氦气与添加多孔吸音材料对轮胎力传递特性和轮胎空腔共振噪声有明显的影响,轮胎跌落噪声和室内转鼓噪声可有效反映轮胎空腔共振特性,轮胎力传递率峰值与空腔共振噪声峰值具有良好的一致性,据此提出了轮胎力传递率可表征轮胎空腔共振噪声的观点。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.
