摘要
基于概率随机理论研究大型集装箱船舷侧外飘砰击特性,预报不同海况和航速情况下船舶非线性运动响应时历,采用Chuang理论计算船艏舷侧区域的外飘砰击压力,对随机海浪下集装箱船外飘砰击概率、砰击压力极值沿船长和高度方向空间分布规律进行分析,在直接预报的基础上给出载荷的确定方法。
Based on randomness theory,the flare impact characteristics of large container ships were studied.The nonlinear motion response of the ship under different sea states and speed was predicted and the flare impact pressure of side region was calculated by the method of Chuang＇s theory.Occurrence probability,magnitude and space distribution of extreme impact pressure were analyzed.The method of determining structure design pressure at the basis of the theory prediction was discussed.
