Abstract

Turbulence caused by the rearview mirror and A-pillar is the main source of interior wind noise. Because of the difference in energy and transfer efficiency of acoustic and turbulent pressure, it is important to accurately identify the two kinds of pressure on the window surface when studying interior wind noise. Wave Number Decomposition (WND) and Pellicular Mode Decomposition (PMD) are successfully applied to decompose the pressure on the window. Furthermore, the transfer function calculated by pellicular analysis is used to calculate the interior wind noise, and the result is compared with the result calculated by the Finite Element Method (FEM) and measured by the experiment. The results revealed that the interior wind noise calculated by the pellicular analysis method is almost the same as the result calculated by the FEM, and that it presents obvious advantages in computational efficiency.

基于Pellicular分析的流动室内噪声实验与数值研究

后视镜和A柱引起的湍流是车内风噪声的主要来源。由于声学和湍流压力在能量和传递效率上的差异，在研究室内风噪声时，准确识别窗户表面的两种压力非常重要。将波数分解（WND）和珀耳模分解（PMD）成功地应用于对窗口压力的分解。此外，利用薄膜分析计算的传递函数对室内风噪声进行了计算，并与有限元法计算的结果和实验测量结果进行了比较。结果表明，采用薄膜分析法计算的室内风噪声与有限元计算结果基本一致，在计算效率上具有明显优势。

期刊介绍： The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world. Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email. IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out. Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model. In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay. The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
