多功能船主吊机区域局部强度计算

多功能船是为了满足海洋工程的发展需要所产生的特种工程船舶,实现了工程经济性与工程实用性的密切结合.借助有限元软件对多功能船主吊机区域局部结构进行分析,描述建立这种复杂不规则模型时需要运用的技巧,建立多功能船主吊机区域局部结构有限元模型,阐述多功能船主吊机区域局部结构有限元结构分析方法,以及在加载过程中应该注意的受力转换.所得到的多功能船主吊机区域局部结构有限元分析结果对同类型船舶的吊机区域局部结构设计和强度分析有一定的参考价值.

Finite element analysis of area under main crane of multi-purpose vessel

Multi-purpose vessel is to meet the needs of the development of marine engineering, special engineering ships, to achieve a close combination of engineering economics and engineering practicality. Area under main crane is ana-lyzed. It describes some useful techniques while building complex and irregular models, a area under main crane FE model is setup, a method of the area under main crane FE analysis is described, and it also discusses the force conversion while apply-ing displacement and force to moles. The proposed method can be used for the design and strength analysis of the ship of area under main crane.
