Abstract
Sound signal of diesel engines contains a lot of abnormal information and fault information. For example, worn-out and failure of components, parts loosing, clearance increasing and poor assemblage will cause various abnormal sounds. The experienced experts can determine the positions and reasons of the faults by listening to the abnormal sounds with their own experiences. This paper used a new method to detect and collect the real-time sound signals of the diesel engines. Digital filtering, wavelet transforms and power spectrum analysis were applied to extract and separate the different sound signals. Meanwhile, abnormal sound signals were analyzed quantitatively in order to extract the characteristic parameters and identify the faults.关键词
