Abstract

Abstract:

In view of that with the effective control of aerodynamic noise at rear-view mirror， A-pillar， and sunroof， the influence of high-speed underbody airflow on vehicle interior noise becomes gradually prominent， the vehicle interior noise induced by underbody high-speed airflow is studied in this paper. Firstly， the interior noise of Hyundai simple model （HSM） caused by high-speed underbody airflow is calculated by applying computational fluid dynamics， combined with finite element analysis （FEA）. The results show that the transfer efficiency of sound pressure excitation is obviously higher than that of turbulent pressure excitation， and the vehicle interior noise first increases and then reduces with the increase of frequency， and mainly concentrated at the low-middle frequency band between 100 and 300 Hz. Then a method of modal acoustic transfer vector （MATV） is introduced and a simulation is conducted on a real vehicle model with its results compared with that of test and FEA calculation， indicating that the results with MATV simulation agrees well with test ones and its calculation efficiency is 96% higher than that with FEA. Finally， an engine bottom closure panel and a frontal air-dam is added on the real vehicle models with corresponding simulations with MATV carried out respectively and the results showing that the total sound pressure level at the same interior monitoring point reduces by 2.8 and 1 dB respectively， compared with that in original real vehicle model.
