얼음과 다양한 거칠기의 판들 사이에서의 마찰특성 연구

Abstract

Ice, which is water frozen into a solid state, has a density of 0.9167 g/cm3 at 0 ℃, whereas the density of water is 0.9998 g/cm3 at the same temperature. It is also a very particular material that does not obey Amonton’s law of friction. Research on frictional phenomena between sea ice and ice-class vessels or platforms in arctic regions is still in its early stage, even though ships and platforms are greatly influenced and moved by the friction force of sea ice. In this paper, various friction tests were carried out, using freshwater ices and model ices in the Korea Research Institute of Ships and Ocean Engineering (KRISO) ice tank, to find the fundamental friction characteristics of ice. We not only measured the friction force between flat plates and ice, but we also analyzed their correlations by measuring the roughness of the plates. This study is intended to contribute to the performance assessment for ice-class vessels and platforms in arctic regions.on.
