摘要： 以225/50R17光面和纵向刻槽子午线轮胎为例，利用有限元软件ANSYS和边界元软件SYSNOISE对在面荷载激励下的轮胎振动与声辐射做了数值计算和分析。在有限元模型中，分别计算了轮胎在受径向接触面力、切向接触面力和侧向接触面力时的位移频率响应。将有限元计算的节点位移响应结果传递到边界元模型中，作为边界元模型的速度边界条件，利用边界元技术分别计算了三种工况下轮胎的辐射声功率、辐射效率和远场指向性。

Abstract: Numerical simulations of vibration and sound radiation of the 225/50R17 smoothing tire and longitudinally grooved tire excited by surface load are carried out by using the FEM software ANSYS and the BEM software SYSNOISE. The displacement frequency responses of the tires excited by, respectively, radial contact force, tangential contact force and lateral contact force are calculated using FEM. Then, the result of nodal displacement responses is used as the boundary condition for the BEM model. The radiation sound power, radiation efficiency, and the directivity of sound in far field in three working cases are computed by means of BEM technique.

Key words: vibration and wave, tire, radiation sound power, radiation efficiency, directivity in far field
