钻井支持驳船克令吊筒体方圆过渡连接形式

On the Transition Connection Type of Crane Boom for Tender Barge

钻井支持驳船大型克令吊简体与甲板下舱壁的连接通常采用方圆过渡的形式，由筒体的圆形截面变化成与舱壁相接的方形截面。针对筒体方圆过渡的形式提出了2种方案，利用有限元分析软件FEMAP分别对这2种方案进行验证分析，并比较2种结构过渡形式的优劣。

The crane boom of tender barge is connected with the bulkhead under main deck. The transition connection type is from circle section to square section. Two design schemes of transition connection type were proposed. A finite element analysis was carried out to assess the structural strength for both design schemes using FEMAP. The advantages and disadvantages of two forms were analyzed comparatively.
