| Abstract: | The self excited ice force is determined, based on the relation curve between anti compress strength and loading velocity as well as the relative motion between ice motion and structural vibration considering the self excited property of ice. The vibration responses self excited by ice of height 40 m jacket platform are calculated. The analysis method for vibration response self excited by ice is presented, it can be employed in the prediction of vibration excited by ice jacket platform. |
