摘要
Abstract
The spectrum characteristics of the main noise sources and the main vibration excitation force of vehicles are analyzed.According to the actual measurement data of the pass-by noise of a passenger car and the vibration signals from a commercial vehicle, the main reasons of the abnormal NVH phenomena are identified using the spectrum analysis technique.Improvement of the vehicles is made according to the diagnosis result.The result shows that the spectrum analysis technique is effective and precise in vehicle's NVH fault diagnosis.关键词
