摘　　要：应用大型有限元软件Abaqus,对某型汽车轮胎进行冲击载荷作用下的内、外声场耦合分析,并在实验室条件下测试了轮胎冲击锤定位敲击试验的辐射声场.数值模拟的轮胎变形、声压分布规律与试验结果一致,这表明数值模拟在轮胎噪声的研究中可以提供有效参考.Based on the finite element software-Abaqus, the acoustic-structure coupling analysis of the inner and outer acoustic field have been made. The numerical simulation present the acoustic distribution of tire＇s inner and outer acoustic field. The impact test of fixed point experiment has been proformed under laboratory＇s condition. The results show that tire＇s deformation and the acoustic distribution consist with that of the experiment. The results of the present study are expected to supply a new reference to study tire＇s noise.
