摘　　要：甲板上浪及其砰击荷载是船舶设计的关键因素之一,为研究波浪荷载作用下船体甲板上浪及砰击荷载分布,以南海作业的FPSO为研究对象,采用光滑粒子动力学方法建立波浪-浮体全耦合时域分析模型。基于实测海洋环境参数,对畸形波及规则波作用下FPSO甲板上浪及船首砰击进行研究。首先对畸形波模拟结果进行验证,然后将畸形波作用下的研究结果与规则波作用下的研究结果进行对比分析。结果表明,畸形波作用下船体的纵摇幅值为规则波作用下的1.3倍,砰击荷载为规则波作用下的1.25倍,基于规则波计算的船体砰击荷载值偏小。Green water and slamming loads are one of the key factors in ship design.To investigate the green water and the wave slamming distribution of the ship under wave loads,the wave-floating body time domain coupling model is established by using smooth particle dynamics method.Based on the measured marine environmental parameters,the green water and the wave slamming of FPSO under the freak waves and regular waves are studied.Firstly,the simulation results of freak waves are verified,and then the research results under the freak waves are compared with those under the regular waves.The research results show that the pitch amplitude of the ship under the freak wave loading is 1.3 times of that under the regular wave loading,and the slamming load is 1.25 times of that under the regular wave loading.The value of the slamming load calculated based on regular waves is too small.
