摘要: 以205/50R16子午线轮胎为对象,建立具有横向花纹沟槽的有限元法分析模型,利用Abaqus/Explicit进行瞬态滚动分析,得到滚动轮胎单个横沟的体积变化。将其导入Fluent中,利用计算流体力学方法对单个横沟泵吸效益流场进行分析,并结合Lighthill声学类比理论预测横向沟槽的噪声,同时基于涡声理论验证流场与噪声之间的关系。结果表明,单个横沟泵吸噪声第一峰值集中在0.8~2.0 kHz附近,仿真数据与试验结果在趋势上具有一致性;且噪声的声压峰值出现在泵吸状态发生转变的时间段;在时域中的3个噪声峰值出现涡量变化较大的时间段,已确定噪声的变化可由涡量来反映。

Abstract: Finite element model of single transverse groove of 205/50R16 tire is developed. The volume change of single groove is acquired from the transient processes by using Abaqus/Explicit solver, and is imported into Fluent. The flow field of air in a single groove is simulated to predict the air-pumping noise by means of Lighthill’s theory. The relationship of flow field and the noise is verifcated based on vortex-sound theory. It is shown that the first sound pressure peak is concentrated at 0.8~2.0 kHz, the trend of simulation date and experimental result have consistency; besides the change of sound pressure happens at transition time of air-pumping. The noise peak occurred on the time period of significant change of vorticity, and the vorticity could reflect the change of flow field noise.

Key words: Air-pumping noise, Tire, Vortex-sound theory
