本发明公开了一种液货船双层底及双甲板区域变纵骨间距的设计方法,具体包括以下步骤:根据货舱横剖面形状,将双层底区域由中线至内底板折角点的平直区域平均分割,分割间距约600mm‑1000mm,在每个分割点设置纵骨或者纵桁;将双甲板区域由中线至内甲板折角线的平直区域平均分割,分割间距约600mm‑1200mm,在每个分割点设置纵骨或者纵桁;在横舱壁布置时,横舱壁每隔3‑5档纵骨间距设置一根垂直桁,垂直桁顶部倾斜到临近的双甲板纵骨位置。本发明的设计方法适用于双壳液货船的结构布置,基于双层底和双甲板区域受力不同,根据双层底和双甲板区域的受力特点分别平均分布各自区域的纵骨,避免了受力有较大不同的区域采用相同的纵骨间距,可有效减轻结构重量,降低成本。
The invention discloses a liquid cargo ship double-layer bottom and double-deck area variable longitudinal space design method which specifically comprises the following steps that according to the shape of the cross section of a cargo hold, the double-layer bottom area is averagely divided from the center line to a straight area of an inner bottom plate bevel point, the division space is about 600 mm-1000 mm, and a longitudinal or a longitudinal girder is arranged at each division point; a straight area from a middle line to an inner deck bevel line of a double-deck area is averagely divided, the division distance is about 600 mm-1200 mm, and a longitudinal bone or a longitudinal girder is arranged at each division point; when the transverse bulkhead is arranged, one vertical truss is arranged on the transverse bulkhead every 3-5 longitudinal bone intervals, and the top of each vertical truss inclines to the position of the adjacent double-deck longitudinal bone. The design method is suitable for structural arrangement of the double-hull liquid cargo ship, the longitudinal bones of the areas are evenly distributed according to the stress characteristics of the double-layer bottom area and the double-deck area on the basis that the double-layer bottom area and the double-deck area are different in stress, the situation that the same longitudinal bone distance is adopted for areas with large stress differences is avoided, the structural weight can be effectively reduced, and the structural stability is improved. The cost is reduced.
