摘　　要：以船舶数值仿真技术为依托,以高速计算能力为基础,结合船体几何重构与变形技术,并将其融入基于现代优化分析理论的设计流程,建立了一种全局流场优化驱动的船舶水动力构型设计新方法/模式,国际上称之为SBD(Simulation Based Design)技术。该文系统介绍了该设计方法的概念内涵和关键技术,对国内外相关研究进展情况进行了总结和评述,并对后续发展趋势以及该方法在船型创新设计中的重要性进行了分析。Hull geometry modification and reconstruction, optimization algorithms and CFD techniques are combined together into what is known as Simulation Based Design （SBD） technique, and itsessence is the hydrodynamic configurations design driven by a global flow optimization. In this paper, essential connotation and crucial components of the SBD in the naval hydrodynamic context are described. And then, numerous domestic and international researches are summarized and reviewed. Finally, the developing trends on hullform design by SBD techniques are analyzed profoundly.
