The stress-strain state of crane structures damaged during operation

Abstract
During operation, crane structures are subject to multidirectional impacts: movement of the crane along the crane track, braking of the crane bridge directed along the crane rail, braking of the crane trolley directed perpendicular to the crane rail. This creates alternating stresses that can cause fatigue failure. In the elements of overhead crane beams and brake structures, fatigue cracks appear and gradually develop, which can ultimately lead to the complete failure of the structures. Another reason for the onset of the limit state of crane structures may be mechanical damage (wear of rubbing parts) and contact with an aggressive environment (corrosion). The aim of the work is to establish patterns of failure occurrence, study the influence of external and internal factors on reliability, establish quantitative characteristics and methods for assessing the reliability of crane structures. For this purpose, it is proposed to develop effective methods for calculating crane structures that have been damaged during operation, taking into account the specifics of the impacts on them and the properties of materials using CAE packages.
