초록
This study conducted four field measurements of local ice pressure during the icebreaking voyage of theicebreaking research vessel “ARAON” in the Chukchi and Beaufort seas from July to August of 2010. For measurements,14 strain gauges, including 8 strain gauge rosettes, were set on the bow of the port side. Influence coefficientswere determined using a finite element model of the instrumented area and they were used to convert the measuredstrains on the hull structure to local ice pressures. The converted maximum pressure was calculated as 2.12 MPa on anarea of 0.28 m2. Pressure-area curves were developed from the surveyed pressure data and the results were comparedwith previously measured data. The study results are expected to provide an understanding of local ice pressures andthus be useful in the structural design of ice class ships.
