摘　　要：从动力学角度研究轮胎花纹噪声的发声机理。分析得出 ,车速越快、轮胎充气量越小、花纹块的密度越大 ,花纹块的噪声声压越大 ;花纹槽的腔体积、车速和汽车载质量越大 ,花纹槽的噪声声压越大。从噪声波干涉与合成的角度论述花纹结构参数对轮胎花纹噪声的影响。The sounding mechanism of the noise from the tire tread patterns was investigated from the point of view of kinetics.The results showed that the higher the vehicle speed,the lower the inflation pressure of tire and the higher the density of tread blocks,the greater the sound levels of the noise from tread bolcks;the larger the volume of tread grooves,and the higher speed and load of vehicle,the greater the sound levels of the noise from tread grooves.The influence of the structural parameters of tread patterns on their noise was described from the point of view of the interference and composition of noise wave.
