Fault Mode Identification of Engine Based on Audible Sound

Abstract:

In this paper, we demonstrate ways of identifying audible sound of working engine to distinguish whether it is in normal condition or faulty condition. A set of experiments were carried out on an engine from a heavy trunk, in order to verify the method, allowing the three sensors located on engine surface to accurately adapt the normal signal and the faulty signal. A technique for faulty mode identification on the engine has been developed based on audible sound. In a practical application of the technique to running engines we capture data of audible sound and a series of analysis were acted on the data, then we could acquire the result to distinguish the state of engine.
