Abstract:Field experiments were conducted in the Bohai Sea to test the friction of sea ice on different materials, such as sea ice. steel and lacquered steel. The influences from different impact factors, for example, the sliding velocity (0.02 m/s to 3.96 m/s). interaction materials (sea ice. steel and lacquered steel), normal stress (3.10 kPa to 11.43 kPa). contacting surfaces of ice (top. bottom and lateral) and ice growth orientation with respect to the sliding direction (vertical and horizontal) on the friction coefficient of sea ice were thoroughly investigated. The results revealed that most of the static friction coefficients between ice and steel and lacquered steel firstly increased with velocity but then decreased at higher velocities with velocity increasing from 0.02 m/s to 3.96 m/s, compared with that of most of the kinetic friction coefficients between ice and steel and lacquered steel, which increased monotonously with increasing velocity. The static friction coefficients between ice lateral surfaces and ice lateral surface were the most of all the static coefficients, and the kinetic coefficients between steel/lacquered steel and ice lateral surfaces were the most of all the kinetic coefficients. Besides, sea ice friction coefficients were independent on normal stress. Finally, the ice growth orientation offered little contribution to the static friction and kinetic friction coefficients.
