摘要
针对穿浪双体船结构设计缺乏合适的设计准则和参考资料的现状,采用船体结构直接设计法,利用国际通用的有限元软件,对该船基座及船体加强结构进行了强度和振动分析,从而实现对该船基座及船体加强结构的优化设计。
Despite the lack of appropriate design rules and references in structure design of wave- piercing catamaran,this paper analyzes the strength and vibration of base frame and its supporting structure with general- purpose FEM software MSC/NASTRAN using hull structure direct design method,and obtains optimization design of the base frame and its supporting structure.
