The aim of this paper is to develop a software, namely HPS-MOP, based on the multi-level and multi-point hydrodynamic optimization of hull-propeller systems during early-stage ship design. An efficient multi-objective evolutionary algorithm is used as the optimization technique to minimize the effective power and maximize the propulsive efficiency with considering some design constraints. Michell’s integral and lifting line theory are, respectively, employed for the hydrodynamic analysis of hulls and propellers in the first-level optimization. At the second level, the boundary element method is applied as a strong tool to predict the hydrodynamic performance of hulls and propellers. The ship added resistance in head waves is estimated using a fast and satisfactory semi-empirical formula. The effectiveness of the approach is illustrated by comparing the optimized results with initial ones in the optimization of series 60 hull form with DTMB P4118 single propeller and S175 hull form with KP505 twin-propeller as the original models.

基于MOEA/D的多工况下船体-螺旋桨系统水动力优化

本文的目的是开发一种软​​件，即HPS-MOP，基于船舶早期设计过程中船体-螺旋桨系统的多层次和多点水动力优化。一种有效的多目标进化算法被用作优化技术，以在考虑一些设计约束的情况下最小化有效功率并最大化推进效率。一级优化中分别采用米歇尔积分理论和升力线理论对船体和螺旋桨进行水动力分析。在第二级，边界元法被用作预测船体和螺旋桨水动力性能的有力工具。使用快速且令人满意的半经验公式估计船舶在迎波中增加的阻力。
