Diagnostic testing of marine propulsion systems with internal combustion engines by means of vibration measurement and results analysis
Abstract
In this paper selected issues concerning vibration diagnosis of the mechanical system within marine propulsion units have been presented, carried out on the basis of experimental examinations of a real object in which an exceedance of the allowable vibration’s level had been observed. Used diagnosing system has been characterised. A procedure of longitudinal and transverse vibrations shaft lines of the mechanical system within marine propusion measurement was presented, with use of portable vibration computerized data logger as well as on the method of vibrations spectral-correlation analysis as a basis of diagnostic process considering dynamic state of analyzed system. Analyzis that has been carried out enabled the selection of the most probable causes for the loss of mechanical system stability. The relevance of the diagnosis was confirmed by the workshop measurements of the torque transmission elements as well as visual inspection of the propellers while the ship was put on a dock.
