摘要
考虑海冰的自激性质 ,根据冰力的抗压强度与加载速率之间的关系曲线以及结构振动与冰流速之间的相对运动关系 ,确定海冰的自激冰力 ,计算高 4 0m导管架平台的冰激振动响应 ;提供平台自激振动的一种分析方法 。
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.
