摘　　要：尝试并实现了iSIGHT优化软件与水动力计算软件HydroSTAR的集成优化,以五体船在波浪中的运动响应及增阻为目标函数,对片体布局作了多目标优化研究.运动计算采用三维频域面元法,增阻计算应用了近场压力积分方程,优化算法采用NSGA-II遗传算法,结果给出了Pareto解,还进行了DOE试验设计分析,为五体船片体布局设计提供参考.Integration of iSIGHT （optimization software） and HydroSTAR （hydrodynamic force calculation softward） is tried and accomplished. Optimization of demihull layout of a pentamaran is studied under objective functions of minimum heave, pitch response and added resistance. Global motions of the pentamaran are evaluated by means of 3D panel method and the added resistance calculated with near-field pressure integral equation. NSGA-Ⅱ genetic algorithm is adopted in optimization. Pareto optimal solution is gained as a result, and design analysis of Design of Experiment （DOE） is carried on, which offers reference for the design of pentamaran demihull layout.
