COMPREHENSIVE PERFORMANCE OPTIMIZATION DESIGN METHOD FOR PENTAMARAN

摘要

A comprehensive performance optimization design method for a pentamaran comprises the following steps: constructing a pentamaran model according to a structural design parameter of a pentamaran; establishing a mathematical model for the pentamaran model, and performing hydrodynamic performance analysis; designing a physical model according to an experiment condition, preliminarily calculating a parameter, and modifying the mathematical model; configuring side hulls of the pentamaran as inclined side hulls having a small angle of attack, and optimizing a layout of the inclined side hulls; performing comparison on bow shapes for the pentamaran, and analyzing resistance performances of the different bow shapes; and determining an optimized pentamaran model, and performing experimental analysis on stability and kinetic characteristics of the optimized pentamaran model. The method performs a simulation experiment and a physical model experiment on the mathematical model of a pentamaran model to provide an optimization solution for a structure of a pentamaran.
