摘要
在分析汽车电气系统噪声产生机理的基础之上,搭建专用汽车模拟实验平台,实际观测金龙大客车的噪声在时域、频域的表现,并应用韦尔奇方法进行功率谱计算,研究汽车电子噪声特性。
Based on the analysis on the generation mechanism of electronic noise in electric system of vehicles, a special simulation experimental platform is built. The observation on the electronic noise of a Kinglong coach in both time and frequency domains is conducted. And the noise power spectra are calculated using Welch technique with the electronic noise characteristics of the coach studied.
