大件运输双体船改造分析

Analysis on Transformation for a Heavy-cargo Transportation Catamaran

采用有限元直接计算方法,对改造的大件运输双体船进行全船结构计算分析。该船由两艘甲板驳拼接而成,用于运输箱梁。结果表明,通过合理的拼接和简单的工序,能将旧船改为符合具体特殊要求的双体船,避免应力集中,较好地承受和传递载荷。

Finite element method was applied to analysis structural strength of a heavy-cargo transportation catamaran.The catamaran was made up by two deck barges to transport the large scaled box girder.It is shown that by using reasonable splice and simple procedure,two old barges could be transformed to a catamaran which satisfied concrete and special requirements,avoiding stress concentration with the required structural strength.
