Abstract

In this paper, friction coefficients between ice and various materials were measured for the clearing resistance study. The friction coefficient is a dimensionless scalar value which describes the ratio of the force of friction between tow bodies and the force pressing them together. The coefficient of friction depends on the materials, roughness on surface, lubrication, etc. We tested and analyzed the friction coefficient for the development of the test methodology. The friction coefficient for ice model test is very dominant to predict the ship performance, so other ice tanks use the unique model ship by themselves. The friction coefficient with moving speed change of ice was studied by using a sample of ship model is made by MOERI's painting technique and the basic research for the developing the painting methodology in MOERI ice model basin was carried out.
