Measurement and Analysis of Engine Noise Based on Near Field Acoustic Holography

  • 摘要: 介绍了近场声全息(NAH)技术的基本原理及基于Helmholtz方程最小二乘法(HELS)的声学重构算法。利用基于HELS算法的近场声全息测试系统对某直列四缸汽油机的整车发动机噪声进行测量与分析,得到不同工况下整车发动机表面辐射噪声的近场全息图。通过对噪声峰值频率下的声压、声强以及表面粒子速度等声场信息的可视化测量结果进行评价,确定该发动机的主要内部噪声激励源与外部近场噪声辐射特性,实现噪声源识别与定位,为其进一步降噪提供依据。
