三体高速客货运输船设计方案概要

多体船与同吨位单体船相比,前者可获得单位面积排水量时更大的甲板面积、良好的横稳性、优良的抗沉性和适航性。高速水运相对于其他运输方式而言,具有装载量大、营运成本低、初始投资少等显著优势。文中以某型具有特定滚装功能(可携带冷藏集装箱、汽车等)的三体客货运输船为例,详细介绍其主要技术参数、设计方案、材料和动力装置的选取情况,总结了三体船的受力特点,对同类型船设计中危险工况确定的强度分析和结构优化具有一定的指导意义。

Design scheme of high-speed passenger-and-freight trimaran

Compared with a monohull, multihulls have greater deck area for unit area discharge, good stability, excellent insubmersibility and seaworthiness. High-speed waterway transportation has notable advantages relative to other transportation modes ,such as great loadage ,low operating cost ,small initial investment,etc. A passenger- and-freight trimaran with special ro-ro function（such as refrigerated containers,cars,etc.）is taken as an example, this paper introduces the selection of main technical parameters, design scheme, material and propelling plant. It also summarizes bearing force characteristics,which can be taken as a reference for determining dangerous working conditions, making intensity analysis and structure optimization.
