顶升装置是保证深海采油平台浮托安装顺利进行的关键装置。针对顶升装置夹持结构中的薄弱环节,提出了一种新型的插板式夹持机构。以支撑筒的内径、高度和插板槽距底面高度为设计变量,支撑筒的总质量最小为目标函数,最大等效应力和最大变形量为约束条件,通过有限元分析软件对新型夹持机构的直接承重部件支撑筒结构进行优化分析,明显减轻了新型夹持机构支撑筒的质量,结构更加简单合理,可靠性高。
The jacking device is the key device to ensure the smooth mounting of the deep-sea oil-bearing platform. Aiming at the weak link in the jacking structure of lifting device, a new type of inserting board clamping mechanism is proposed. Taking the inner diameter and height of support cylinder and the height of the bottom of slot plate as design variables, the minimum total mass of support cylinder as objective function, the maximum equivalent stress and the maximum deformation as constraint conditions, the new type of clamping mechanism Of the direct load-bearing components of the cylinder structure optimization analysis, significantly reducing the quality of the new clamping mechanism support cylinder, the structure is more simple and reasonable, high reliability.
