METHOD FOR ASSESSING THE RELATIONSHIP BETWEEN THE CHARACTERISTICS OF VIBROACTIVITY AND THE DESIGN PARAMETERS OF A MARINE DIESEL

Protection of the crew and passengers from vibration and noise of machines, auxiliary mechanisms and propeller, as well as reduction of sound emission into the surrounding space, are paramount tasks in solving the problem of vibration and noise in shipbuilding. The magnitude of the level of vibration and noise affects the performance, well-being and health of people, the operation of equipment and mechanisms, etc. It should be noted that vibration not only has a negative physiological effect on the human body, but also serves as a source of airborne noise. Noise values are determined mainly by the acoustic and vibrational power generated by the source. The determination of defects by vibration parameters is one of the most intellectually intensive sections of diagnosing reciprocating machines, which include marine engines. The studies presented in this paper are aimed at eliminating these gaps, primarily on the basis of a more complete description of vibrational processes. The article presents the results of a study related to the control, diagnostics and evaluation of the technical condition of an internal combustion engine running on diesel fuel. The possibility of establishing a connection between the vibrational parameters of the engine and the change in its design characteristics during operation is shown. The results of the work of the analytical and experimental information system for monitoring the vibration activity of diesel engines are presented.
