3万 m3 LNG 船结构设计

摘要

The structural design of the medium sized TYPE C 30 000 m3 LNG carrier is introduced .According to the design principles of effectiveness , continuity and equidistant of member pass , under the premise to meet the structural rules and regula-tions, the node connection is optimized for the better transition and reducing stress concentration of structural component .The structural features of bow, stern, cargo area, engine room area and typical hull structure are analyzed .The results of direct strength analysis demonstrated that the yield strength , buckling strength and ultimate strength met regulatory requirements .%中小型TYPE C型3万m3 LNG船结构设计遵循构件传力的有效性、连续性和等间距性原则，在满足规范的前提下，优化节点，使结构过渡良好，尽量避免应力集中，分别从艏部、货舱区、机舱区、艉部等典型结构上分析其结构特点及选型依据，有限元分析结果表明：结构屈服、屈曲和极限强度均满足规范要求。
