三体船重量分布对波浪载荷的影响

摘要

Usually the trimaran's loading states are variational for their different operating requirements such as executing mission,voyaging time,sea area etc. Based on the 3-D potential fluid theory and Simple Green Function method, this theme designed four different typical weight distributions, then calculated and gave the long term prediction of a trimaran's section wave loads respectively, finally analyzed the influence of longitudinal weight distribution on trimaran's wave loads. The results indicate that the equality of longitudinal weight distribution is helpful to reduce wave loads.%三体船根据执行任务、续航时间、航行区域等实际要求,存在着不同的载重状态.文中基于三维势流理论和简单格林函数法,分别对三体船4种典型重量分布情形下的剖面波浪载荷进行长期预报,比较分析了纵向重量分布对三体船波浪载荷的影响.结果表明,三体船全船纵向重量分布更加均匀,有助于降低剖面波浪载荷.
