抄録(英) | In the context of electrification, Pass by noise and Acoustic Vehicle Alerting System regulations are challenging OEMs who can benefit from the use of virtual prototyping in the pre-certification phase. It has already been shown that deterministic methods such as BEM or statistical methods such as Ray tracing can effectively support the acoustic pre-certification of vehicles, but there is a need, when dealing with certification noise levels, to accurately predict acoustic performance with the right compromise between solver speed and accuracy. Accelerated BEM methods can therefore represent a good compromise between speed and accuracy compared to standard BEM methods which can be computationally expensive and Ray tracing methods which can provide quick predictions at the expense of accuracy. This paper presents a comparison of accelerated BEM (H-Matrix), standard BEM and Ray tracing methods for Pass by noise and Acoustic Vehicle Alerting System prediction. 翻訳 |
