11.9m双体交通艇总强度有限元分析

双体船因其甲板面积大、稳性好等优点在近几年备受关注。双体船的两个片体由中间的连接桥连接而成,连接桥在航行环境中要遭受比较大的横向弯矩和扭转力矩的作用,其自身的强度对双体船的安全性来说至关重要。本文在有限元理论的基础上,采用直接计算方法对某双体船进行了横向强度和扭转强度的最上层主甲板以下全船结构有限元分析。对其总横强度及扭转强度进行了校核,并根据应力云图提出了双体船在设计时应注意的几点建议。

FEM analysis on an 11.9m traffic catamaran resultant intensity

Catamaran has been put more attention recent years because of its virtue of large deck area, fine stability etc. The two demihull of catamaran are connected by the middle cross structure, cross structure will be exposed to the effect of relatively large transverse bending moment and twisting moment during navigation environment, its strength is very important to the safety of catamaran. The paper adopted directly calculation methods analyzing the transverse strength and torsional strength of whole structure...
