【摘要】 吊耳是船舶分段翻身、运输、吊装过程中常用的部件,吊耳强度直接决定吊装作业的安全性。吊耳的设计可以采用简化分析、接触有限元及简化有限元等方法,本文对各种设计方法进行整理,并利用不同的方法详细分析了吊耳的强度,通过分析对各种分析方法进行评价及改进;对应用MSC.Nastran进行简化有限元分析过程中的载荷大小、施加范围、施加形式等作了讨论。本文提出的简化有限元分析方法具有应用简便、计算精度满足工程需求并容易被船厂工程技术人员掌握的特点。更多还原

【Abstract】 Hanger is essential components used to ship block turning over,transportation and lifting.The strength of hanger is critical factor for lifting safety.These methods,such as simplified theoretical analysis,finite element analysis using contact theory,simplified finite element analysis,can be used for designing the dimension of hanger.Firstly,the theory and analysis process of these methods are introduced and discussed.Then the strength of hanger is evaluated by using of three methods. And the comment on each method is made.Lastly the size,range and type used in simplified finite element analysis via MSC.Nastran is discussed.The method of simplified finite element analysis with the characteristics of application simply, high accuracy meet the needs of engineers and technicians.更多还原
