Abstract

Tire acoustic cavity resonance noise (TACRN) contributes significantly to the interior noise of electric cars and passenger cars with lower powertrain noise, which affects the comfort of the ride. To suppress TACRN effectively, it is crucial to clarify the characteristics of TACRN. In previous studies, the acoustic wave in the tire acoustic cavity is straightforwardly assumed to be the plane wave for convenience. In fact, there exist strict conditions for the acoustic wave propagating in the pipeline to act as a plane wave. The aim of this paper is to make the characteristics and evolution of acoustic waves in tire acoustic cavities clear. To do so, a simplified model of the tire cavity is established, and the sound field distribution and the acoustic wave propagation characteristics in the tire cavity are analyzed based on the theory of acoustic waveguide. Then, the existence ranges of higher-order waves (non-plane waves), the conditions of an acoustic wave evolving into a plane wave, and the frequency range of a plane wave are investigated. Finally, the characteristics and evolution law of an acoustic wave in a tire acoustic cavity are obtained. The work in this paper may deepen the understanding of the characteristics and mechanism of acoustic waves in the tire cavity and be helpful and meaningful for analyzing and suppressing TACRN. Therefore, it is of practical significance to reduce TACRN transmitted to the vehicle and improve the sound quality inside the vehicle.

轮胎声腔中声波作为平面波作用的条件及影响因素研究

轮胎声腔共振噪声（TACRN）对电动汽车和动力总成噪声较低的乘用车的内部噪声有很大影响，从而影响乘坐的舒适性。为了有效抑制TACRN，阐明TACRN的特性至关重要。在以前的研究中，为了方便起见，直接将轮胎声腔内的声波假设为平面波。事实上，在管道中传播的声波作为平面波存在严格的条件。本文的目的是弄清轮胎声腔中声波的特征和演变过程。为此，建立了轮胎空腔的简化模型，并基于声波导理论分析了轮胎空腔中的声场分布和声波传播特性。然后，研究了高阶波（非平面波）的存在范围、声波演化为平面波的条件以及平面波的频率范围。最后，得到了轮胎声腔中声波的特性和演化规律。本文的工作有助于加深对轮胎胎腔声波特性和机理的理解，对分析和抑制TACRN有一定的帮助和意义。因此，减少传输到车内的TACRN，提高车内音质具有重要的现实意义。
