Application of acoustic emission for detection of fatigue microdemage in main and crank bearings for diesel engines
Abstract
The article presents reasons for applying the acoustic emission (AE) to detect fatigue microdamage in main bearings and crank bearings of ship main engines. Problem of determination of the fatigue life for slide bearing bushes was characterized in general. There were demonstrated properties of the objects of research, which were bushings made of the MB58 alloy, as well as an overall description of the research. It was shown that the frequency bands of AE signals can indicate fatigue damage to the sliding layer of a bearing bush. The fatigue damage in the tested bushes was depicted in figures. General features of the AMSY-6 measuring system, used in the research, were also provided herein.
