Abstract: Laboratory tests were performed to simulate the dynamic interaction of cylinder, slender structure and moving ice sheet. Specific laboratory preparation procedures and parameters design that are fundamental to the physical mechanism of interaction are described. Ice induced self-excited vibrations were observed in tests and frequency lock-in phenomenon was achieved. Simulation in the laboratory of full-scale ice-structure interactions reveals good agreement with field data and theoretical mechanisms validating self-excitation theory.
