The invention belongs to the technical field of ships, and discloses a layout method of an independent liquid cargo tank supporting structure, according to the layout method of the independent liquid cargo tank supporting structure, when the pressure bearing requirement is met, the layout method is optimized through the step S8, and on the premise that the initial layout meets the pressure bearing requirement, the step S81 is utilized firstly, and the step S12 is utilized secondly; the method comprises the following steps: step S82, removing supporting structures at corresponding positions at equal intervals so as to reduce the number of the supporting structures, determining actual allowable stress sigma on a single supporting structure, calculating the minimum plate thickness size B of the supporting structure according to a formula # imgabs0 #, and reducing the plate thickness size of the supporting structure according to the minimum plate thickness size B so as to obtain the plate thickness size of the supporting structure. The optimal plate thickness size of the supporting structures is determined, and the layout mode with the minimum number of the supporting structures and the minimum plate thickness size is obtained, so that the utilization rate of resources is improved, the manufacturing cost is reduced, and the manufacturing period is shortened.
本发明属于船舶技术领域,公开了一种独立液货舱支撑结构的布设方法,该独立液货舱支撑结构的布设方法,在符合承压需求时,通过步骤S8对布设方法进行优化,在初始布局符合承压需求的前提下,先利用步骤S81,等间隔的撤去对应位置处的支撑结构,用以减少支撑结构的数量,在利用步骤S82,确定单个支撑结构上的实际许用应力σ实,根据公式#imgabs0#计算出支撑结构的最小板厚尺寸B,并根据最小板厚尺寸B,对支撑结构的板厚尺寸进行缩减,确定支撑结构的最优板厚尺寸,获得支撑结构数量最少,板厚尺寸最小的布设方式,从而提高资源的利用率,降低制造成本,缩短制造周期。
