THE METHOD OF MATHEMATICAL MODELING OF ICE ABRASIVE EFFECTS ON BERTHING FACILITIES

Abstract

The ice cover has a significant abrasive effect on the surface of marine engineering structures. In areas with high dynamics of ice cover drift, one of the most important problems of providing load-bearing capacity of structural elements is to determine the intensity of their wear from abrasion by drifting ice. The magnitude of ice abrasion depends on many factors, the main of which are: contact pressure, abrasion path length and material resistance to ice abrasion. The length of the abrasion path and the magnitude of the contact pressure are determined by the processes of drift of ice formations and their interaction with the structure. To assess them, it is necessary to have a mathematical model for calculating the ice load. At the same time, experimental studies of various materials for resistance to ice abrasion make it possible to establish an empirical dependence of the intensity of ice abrasion. The combined use of a theoretical model of interaction and an empirical model of material destruction makes it possible to create a method for calculating the depth of ice abrasion. The article discusses the method of mathematical modeling of ice abrasive effects on berthing facilities.
