摘要
以一艘三体船为例,采用基于三维线性势流理论的流体动力计算程序,进行船体波浪载荷的长期预报,并将波浪载荷的长期预报值与英国劳氏船级社三体船规范计算值进行比较分析。结果表明,在现有条件下预报结果具有一定的准确性,可用于指导船体初步结构设计。
With a trimaran as example, this paper utilizes hydro-dynamic calculation program based on three dimensions linear potential flow theory to carry out long-term forecast on hull wave load, and make comparison and analysis of the long-term forecast value of wave load and the calculation value of LR trimaran rules. The result shows that the forecast under current condition has determinate veracity and can be served as a guidance for preliminary hull structure design.
