摘要
采用有限元计算软件MSC.Patran对某气垫船首部船底结构进行瞬态响应分析,对加筋板悬挂式结构及常规切口式船底结构分别建立有限元模型,计算2种船底结构在受波浪砰击载荷下的瞬态响应特征,从其局部强度和局部振动特性对比分析得到抗砰击效果较好的气垫船船底结构,为该型艇的结构设计提供参考。
The transient response on bottom structure of the air cushion vehicle under slamming load is calculated in this paper to compare stiffened plate hanging structure with regular open cut structure separately founded and calculated by finite element software Patran.The better bottom structure of air cushion vehicle to resist slamming has been gained in the aspects of local strength and local vibration character,furthermore,the reference has been applied to the air cushion vehicle structure design.
