摘　　要：以某18万吨级散货船为例,以焊接型底边舱折角和圆弧型底边舱折角2种形式为研究对象,对散货船底边舱折角进行优化设计。分别选择轻货舱、重货舱和重压载舱分析结构布置形式对应力水平和疲劳的影响;从应力、疲劳和工艺等方面对焊接型折角和圆弧型折角进行比较。在此基础上,研究圆弧半径对折角应力和疲劳的影响。Taking the welded and radiused types of hopper knuckle on 180 000 DWT bulk carrier’s cargo hold as an example, the influence of different structure configuration on hopper knuckle’s stress and fatigue has been analyzed under light cargo, heavy cargo and heavy ballast loading conditions. A comparison on stress, fatigue and construction technology for the two types of hopper knuckle has been made. Further the influence of radius on stress and fatigue of the radiused type of hopper knuckle has been investigated.
