摘　　要：以某铝合金船体结构的工程船为例,采用有限元方法对该船的全回转液压伸缩折臂吊机基座及其附近加强结构建立模型,并依据BV船级社规范NR526的要求对该吊机的基座及周围加强结构进行强度分析.结果显示,在各种工况下,吊机基座及其周围结构的屈服强度都满足BV船级社的规范要求.在此基础上总结了结构优化的方法,为该类型基座及其加强结构的设计和优化提供参考.Taking an aluminum structure work ship as an example,The FEA method is used to make the model Hydraulic Foldable Knuckle Boom Marine Crane foundation and its nearby reinforced structure,and the strength analysis of the foundation and reinforced structure is carried out according to the requirements of the BV class rules NR526,To verify that the final foundation and nearby structure's yield strength satisfy the requirement of BV rule NR526,on this basis,the method of structure optimization is summarized,and provide reference for the design of the foundation and its reinforcement structure.

关 键 词：工程船 有限元 吊机基座 屈服强度
