19.8m豪华游艇主尺度确定及主机功率估算

Determining Principal Dimensions and Estimating Main Power of a 19.8m Yacht

在游艇设计初期,往往因为设计任务书中已知信息较少而难以较准确地确定游艇的主尺度和主机功率。以一艘长为19.8m的游艇为例,给出了游艇设计初期只已知排水量、最大航速和总长的情况下各主尺度的确定方法。并结合大隅三彦功率估算方法和作者提出的母型艇系列拟合方法得出主机功率的估算值,为游艇设计中主机选型和成本估算做准备。

At the initial stage of a yacht design, it is always difficult to determine principal dimensions and choose main engine because of little information given. In this paper, for the 19.8m yacht, a method is given for determining principal dimensions while the displacement, maximum velocity and length are provided. By combining the Daisumi Mihiro method into the present method proposed, the main engine power is calculated for selection. The method demonstrated here is expected to apply the initial design of a yacht.
