摘要
本文以一条三体无人船为计算对象,详细说明了一种利用"叠模"法和"细长体"理论为分析手段,观察目标三体无人船在一系列不同中间片体位置和片体间距条件下的粘性阻力和兴波阻力特性,并通过计算分析,寻找粘性阻力和兴波阻力随中间片体位置、片体间距的变化规律,进而以优化设计航速时的阻力为设计目标,并最终确定中间片体设计参数最佳方案的方法.
In this paper,a new type of umanned trimaran is chosen as the analysis target.It makes description of an approach that through stack model method and slender body theory,the characters of viscous resistance and wave resistance of the trimaran under different mid-hull position and distance of hulls can be found out.Then the change rule of viscous resistance and wave resistance induced by the change of mid-hull position and distance of hulls would be got with these data,which would be helpful for making the best resistance plan of trimaran under the aim of optimizing the resistance performance at design speed.
