Diesel engine noise source identification based on EEMD, coherent power spectrum analysis and improved AHP

Abstract: As the essential foundation of noise reduction, many noise source identification methods have been developed and applied to engineering practice. To identify the noise source in the board-band frequency of different engine parts at various typical speeds, this paper presents an integrated noise source identification method based on the ensemble empirical mode decomposition (EEMD), the coherent power spectrum analysis, and the improved analytic hierarchy process (AHP). The measured noise is decomposed into seve… Show more

“…Therefore, scholars studied the single channel method to separate and identify the noise sources of internal combustion engine. For example, Zhang et al [11] adopted the ensemble empirical mode decomposition, the coherent power spectrum analysis, and the 2 Shock and Vibration improved analytic hierarchy process to separate and identify the noise sources of the diesel engine. Bi et al [12] utilised the EEMD-RobustICA method to separate the combustion noise, piston slap noise, and exhaust noise of the gasoline engine.…”

“…e overall noise was decomposed into five frequency bands, and one operating speed was considered. Zhang et al [19] proposed a combined AHP approach to analyse the contribution of different engine parts to the overall radiated noise in different engine speeds. e decomposition by ensemble empirical mode decomposition (EEMD) was affected by the modal aliasing problem in intrinsic mode functions (IMFs).…”
