摘要

燃料电池轿车的一个突出问题是其空气辅助系统所产生的高频噪声,其中又以空气压缩机所产生的噪声为最大。本文采用的压缩机类型为旋涡风机,通过测量其稳态和非稳态工况下其前侧和出口处的噪声,分析其噪声特性。得出旋涡风机噪声具有显著的离散峰值,以10倍频,42倍频和84倍频最为显著。通过Fluent软件仿真计算旋涡风机工作时的内部压力波动,解释了旋涡风机产生倍频噪声的原因

Abstract

A significant problem of fuel cell vehicles is high-frequency noises caused by air support system, and the air compressor generates the maximum noise. The vortex blower is adopted as the compressor. The noise of the vortex blower at the front and outlet was measured and analyzed under steady and unsteady conditions. It is concluded that there are discrete peak frequencies and the 10 times, 42 times, 84 times frequencies are the most significant. By simulation of interior pressure fluctuation of the vortex blower using Fluent, the cause of the harmonic frequencies is explained.
