【摘要】 多航态高速双体船是最新提出的一种概念型双体船舶,顾名思义,它拥有多种航行姿态,包括:潜水航行态、滑行航态、垫升航态和普通排水航行态。多航态高速双体船集合了多种船舶的特点,目前尚无在役实船,与以前所说的复合型船舶比较类似,不过比复合型船具有更多的航态特点。本文通过对多航态高速双体船的结构设计从概念设计开始,到完成比较合理详细的初步设计,为这种新型的概念型船的结构设计给出了适合其本身特点的结构型式。由于此前没有这种船舶的研究,所以对其的结构设计既不能遵照以前内河双体船结构设计规范,也没有任何的母型船资料可供参考,设计中遇到了比较棘手的问题,属于开拓性的研究设计。本文主要内容是:结合多航态高速双体船的自身特点,如型线特点、航态特点等,依据目前潜艇结构、气垫船结构以及内河双体船结构的型式对该高速双体船的结构型式进行了初步设定。以结构力学为基础,利用直接计算法,对该高速双体船的结构初步设计计算,对其中该高速双体船的几个危险工况下进行了结构的强度与稳性校核,得出一个较为合理的结构。最后,利用结构有限元分析软件ANSYS对该双体船的潜水航态以及斜置波浪上两种情况分别进行了计算,通过计算结果来对前面设计的结构进行进一步的研究。本课题具有较强的工程背景及参考价值,为今后多航态高速双体船的设计提供重要的数据和参考。更多还原

【Abstract】 The multiple sail poses high speed catamaran is a new type catamaran, just as its name implies, it has a lot of sail poses, include submergence, sliding, air cushion and common sail pose. The multiple sail poses high speed catamaran gathers characteristics of many ships, however, there is not existing one. It is similar with complex ship, but it has more sail poses.This paper is from the conceptual design of the multiple sail poses high speed catamaran’s structure, to accomplishing more logical preliminary design. It takes the structure mould according with the multiple sail poses high speed catamaran’s own characteristic. Because there is not any research about it, we can not conform to freshwater catamaran criterion and have no reference ship, what’s more, encounter lots of difficulties in structural design. This paper is a pioneer of the multiple sail poses high speed catamaran’s structural design.This paper’s main content includes the following parts. Fistly, combine the own characteristic of the multiple sail poses high speed catamaran, such as form, sail things and so on, the basic form of structure is designed, refering to present submarine ship structure, hovercraft structure and freshwater catamaran structure. Secondly, base on structural mechanics, using direct calculating method, this paper computes more structural intensity and stability of this catamaran, and find a suited structural form. Finally, calculating about two status of the catamaran, which are submergence and partial hull on the wave, through finite element analysis, and study on the results above. This subject has strong engineering background and application value, which can provide important data and referance for the design of catamaran for the future.更多还原
