| 摘 要： | 三体船连接桥结构波浪设计载荷的确定对结构设计中关注的横向强度问题来说是非常重要的.为了研究一艘三体船连接桥横向波浪载荷,进行了该三体船的水池模型试验,包含不同浪向下规则波与不规则波试验.试验对连接桥遭受的分离弯矩Msp、分离剪力Qsp和横向扭矩Mtt进行了测量,分析了其传递函数和统计的特性.根据对这些连接桥横向波浪载荷在试验值、推断值与规范计算值之间的比较分析表明:劳氏规范关于这些横向波浪载荷的计算值可能对应于规则波双幅波高6.0m;对于不同的横向波浪载荷来说,保证率为99%的设计载荷推断值对横向扭矩Mtt来说要大于规范计算值,而分离弯矩Msp和分离剪力Qsp的推断值对应的规范计算值则相当,这意味着没计人员在用劳氏规范进行校核时,横向扭矩Mtt的规范计算值是偏向于冒险的,应给予特别关注.

| Abstract: | It is very important to obtain the cross structure design wave loads of a trimaran for its transverse strength in structure design.In order to study the cross structure design wave loads of a trimaran,its model test was performed in a seakeeping tank.The model test conditions were composed of regular and irregular waves in head and quartering seas.Splitting moments Msp,splitting shear forces Qsp and transverse torsional moments Mtt of the cross structure were measured in model tests.RAOs and statistical pro... |
