- Abstract
Vibration tests on a diesel engine were done in the idling condition, and through the analysis of the test data, the faulty part was determined. Due to the vibration transfer characteristics, the vibration characteristics of the engine oil pump body were analyzed, and the fault related to the oil pump was further determined. Vibration tests were respectively carried out on the faulty engine and fault-free engine, the test signals were compared and analyzed, and thus, the existing fault of the oil pump was determined through the study of signal data. Based on wavelet denoising and frequency spectrum analysis of vibration signals, the common features of such fault are summarized, and the reasons for the fault are successfully diagnosed.
