　　A series of tests of a full-scale river icebreaker was conducted to investigate the characteristics of ice-induced hull vibration. The test was conducted when the river icebreaker was operating in an ice-covered river at temperatures of -4 to 0 °C with ice thicknesses of 300 to 400 mm. In the tests, the ice condition and icebreaker speed were chosen as the main influence factors. By analyzing the measured test data, we identified some important points regarding ice-induced hull vibration. When t...
