The invention relates to the technical field of ship construction, in particular to an in-dock ship launching process simulation check optimization method, a storage medium and equipment. According to the method, the three-dimensional finite element model of the whole ship is established, the structural strength of the ship body is calculated before stowage, after stowage, in the critical floating state and in the full floating state according to the weight distribution of the calculation stations and the arrangement of the docking blocks, and the stress states of the docking blocks are calculated before stowage, after stowage and in the critical floating state; when the calculation result does not meet the requirement, the modes of enhancing the ship structural strength, adjusting the docking block arrangement form, changing docking block structural parameters and the like are specifically adopted, so that the calculation results in all the steps meet the requirement, and a more reasonable docking block arrangement scheme and a more reasonable launching scheme are obtained; the critical floating state of the whole launching process is estimated in advance, and the local strength of the ship body in the whole launching process is checked.
本申请涉及船舶建造技术领域,具体而言,涉及一种坞内船舶下水过程模拟校核优化方法、存储介质及设备。本申请通过建立全船的三维有限元模型,并根据计算站的重量分布和坞墩的布置,在配载前、配载后、临界起浮状态和全浮状态分别对船体的结构强度进行计算,在配载前、配载后、临界起浮状态分别对坞墩的受力状态进行计算,在计算结果不满足要求时,针对性的采用加强船舶结构强度、调整坞墩布置形式、改变坞墩结构参数等方式,使得各步骤中的计算结果均符合要求,获得更合理的坞墩布置方案及下水方案,提前预估整个下水过程的临界起浮状态并校核船体整个下水过程中的局部强度。
