为了快速获得具有良好阻力性能的实用船型，基于线性兴波阻力理论，利用非线性规划(NLP)方法，讨论了总阻力最小的船型优化设计方法。以总阻力为目标函数(兴波阻力采用米歇尔积分计算，摩擦阻力采用等效板摩擦阻力公式计算)，以船体表面偏移量为设计变量，以适当排水量为基本约束条件，考虑附加约束条件，对船首形状和整船进行了优化，得到了一种改进的船型。用CFD方法计算了优化前后船舶的阻力，以进一步评估优化后的减阻效果和性能。最后，给出了一个实际高速船的优化计算实例。明显的减阻效果证实了优化设计方法的可靠性。
Abstract In order to quickly obtain practical ship forms with good resistance performance, based on the linear wave-making resistance theory, the optimal design method of ship forms with minimum total resistance is discussed by using the non-linear programming (NLP) method. Taking the total resistance as the objective function (the Michell integral is used to calculate the wave-making resistance and the equivalent plate friction resistance formula is used to calculate the frictional resistance), the hull surface offset as the design variable and appropriate displacement as the basic constraints, and considering the additional constraints, the hull bow shape and the whole ship are optimised, and an improved hull form is obtained. The resistance of the ship before and after optimisation is calculated by the CFD method to further evaluate the resistance reduction effect and performance after optimisation. Finally, an example of optimisation calculation of an actual high-speed ship is given. The obvious resistance reduction results confirm the reliability of the optimisation design method.
