Ship Design and Optimization of High Performance SWATH

小水线面双体船具有推进效率高、耐波性能好、高速航行时阻力小等优点,本文将针对小水线面双体船在波浪中的阻力性能特点进行分析,并根据片体支柱距离的变化设计出优化方案,利用MAXSURF仿真模拟验证设计方案,得到不同支柱间距t时的兴波阻力系数变化规律,并分析其优化的合理性与实用性。

Small waterplane catamaran has the advantages of high propulsion efficiency,good wave resistance and low resistance during high-speed navigation.This paper will analyze the resistance performance characteristics of small waterplane catamaran in the wave,and according to the distance of the strut pillar.The change design is designed to optimize the design scheme by using MAXSURF simulation to obtain the variation law of the wave-making resistance coefficient when the distance between different pillars is t,and analyze the rationality and practicability of the optimization.
