摘要
针对某中型邮轮,应用由线型优化软件CAESES与计算流体动力学(CFD)软件SHIPFLOW组成的数值优化平台,根据母型船的主尺度特征,建立全参数化船型曲面表达。设定多个自变量,以服务航速下的最小收到功率为优化目标,采用Sobol和TSearch方法对该船的线型及球艏局部进行优化分析,考虑船桨匹配,得到优化后的线型方案。检验优化船型的波浪增阻性能,结果表明该线型优化方法是可行的。
For a medium cruise ship,a numerical optimization platform composed of hull line optimization software CAESES and computational fluid dynamics(CFD)software SHIPFLOW is applied to establish a fully parameterized ship form surface representation according to the main dimension characteristics of the mother ship.Several independent variables are set,and the minimum delivered power at service speed is set as the optimization objective.Sobol and TSearch methods are used to optimize the lines of shape and bulbous bow,and the optimized lines take the hull-propeller matching into account.The optimized hull’s performance of added resistance in regular waves is examined,and the results demonstrate the feasibility of the adopted line optimization method.
