摘要
Abstract
To identify the noise sources and vibration sources quickly without disassembling coupling components, a multi-input/single-output system model is established by using the operational transfer path analysis. Independent sound sources and major vibration sources are identified with the partial singular value analysis. The contribution to interior noise of each structure path is calculated. The synthetic noise at the objective points is compared with the measurement noise. The model is verified by comparing the prediction noise with the real noise after removing some transfer path under idle working condition. This method can be used to analyze the vehicle’s interior noise transfer path widely.关键词
