摘　　要：此文通过试验研究了垂直安放的单个弹性圆柱在规则波作用下的纵向振动响应,并与求解弹性柱体的运动方程得到的响应结果进行了比较,其中运动方程中描述柱体所受的水动力。对比使用了Morison公式,以及绕射理论的计算方法,由试验和理论解的结果给出Morison公式的适用性范围。The in-line response of a vertical flexibly mounted cylinder in regular and random waves is reported in this paper.Both theoretical analyses and experimental measurements have been performed.The theoretical predictions are based on the Morison equation which is solved by the incremental harmonic balance method.Experiments are then performed in a wave flume to determine the accuracy of the Morison equation in predicting the in-line response of the cylinder in regular and random waves.The interaction between waves and vibrating cylinders are investigated.
