摘要/Abstract

摘要： 为研究特种车车内声品质,对3辆不同类型特种车进行实车道路实验,建立了主观评价烦躁度和声品质客观参数之间的Kriging模型,通过滤波分析得到不同频段声品质参数对主观评价结果的影响。建立了混合FE-SEA模型,以计算车内中频噪声,并与实验数据进行对比,验证模型精度。计算了车身主要板件对车内中频噪声的声学贡献度,找到对车内声压贡献较大的板件,并对其进行优化,有效降低了车内中频噪声。

关键词: 声品质, Kriging模型, 中频噪声, 降噪

Abstract: In order to study the interior sound quality of special vehicles, the road tests of three different types of special vehicles are carried out, a Kriging model is established, describing the relation between subjective rating of annoyance and objective parameters of sound quality, and the effects of the objective parameters of sound quality on subjective evaluation results in different frequency bands are obtained by filtering analysis. A hybrid FE-SEA model is set up to calculate the interior medium-frequency noises, which are then compared with test data to verify model accuracy. The acoustic contribution of key panels to interior medium-frequency noises are calculated, based on which panels with larger contribution are found and optimized, thus the interior medium-frequency noises are effectively reduced

Key words: sound quality, Kriging model, medium-frequency noise, noise reduction
