摘要

轮胎噪声由于其在车辆噪声、振动和不平顺性（NVH）以及噪声调节中的重要性而受到极大关注。本研究证明了在声-结构耦合有限元分析中，考虑胎面复合材料模型对滚动轮胎噪声的数值预测。针对轮胎结构振动中的频率相关阻尼，建立了粘弹性主曲线。数值计算发现，储能模量（E’）和损耗模量（E“）分别大230.4%和1428%的胎面复合材料，导致结构噪声大1.16-9.79%。此外，胎面复合材料的弹性模量（E）与轮胎噪声成比例相关，这表明低噪声轮胎需要降低的弹性模量和粘弹性模量。这项研究有助于深入了解如何设计复合材料的特性，特别是粘弹性，以控制下一代结构中的结构噪声和振动，如自动驾驶电动汽车和城市空气流动性。

Experimental and numerical investigation on the effect of material models of tire tread composites in rolling tire noise via coupled acoustic-structural finite element analysis

Tire noise has received enormous attention for its importance in vehicle noise, vibration, and harshness (NVH) along with noise regulation. This study demonstrates a numerical prediction of the rolling tire noises considering tread composite material models in the coupled acoustic-structural finite element analysis. The viscoelastic master curves were developed for the frequency-dependent damping in the structural vibrations of the tire. It was numerically found that the tread composites with 230.4% and 1,428% larger storage (E’) and loss moduli (E”), respectively, resulted in 1.16–9.79% louder structure-borne noises. Moreover, the elastic modulus (E) of the tread composites was proportionally related to the tire noises, suggesting that reduced elastic and viscoelastic moduli are desired for low-noise tires. This study can contribute to thoroughly understanding how the composite material properties, particularly viscoelasticity, can be designed to control structural noise and vibration in next-generation structures such as autonomous electric vehicles and urban air mobility.
