NOISE INVESTIGATION OF A RAILROAD DIESEL ENGINE

This study presents an investigation of noise generated by the vibration of structural components of a railroad diesel engine of the GM 645 E Series. A method of correlating the vibrations of certain high vibration components of any machinery with its total noise field has been developed. This method can be applied to a close semi-reverberant field in the presence of multiple noise sources of similar character. Furthermore, percentage contribution to the total noise from the individual structural components can be determined. One third octave band analyses of the effective engine noise and measured vibrations of the engine components have been performed. These vibration and noise signals have been cross-correlated.
