【摘要】 本文用理论方法计算了兴波阻力和改良船型的型值。理论计算可分下列两种情况: (1)对基本船型的水线迭加曲线薄船函数以计算其对应的改良船型。 (2)对基本船型的曲表面迭加曲面薄船函数以计算其对应的改良船型。 本文利用C.C.Hsiung提出的用tent函数方法计算兴波阻力。用SUMT混合罚因子优化技术计算改良船型的型值。 本文以y=(1-x~2)(1-z~4)数学船型和Series 60实用船型为基本船型,用tent函数方法对它们进行了兴波阻力计算,并且与其它兴波阻力计算方法进行了比较。本文还以上述两种船型为基本船型进行了改良船型的计算,并且得到了与它们相应的理论改良船型。更多还原

【Abstract】 The wave resistance and the offset of improved ship form are calculated by theory method. The theory calculations may be divided the following two cases:(1) Appending curve thin ship functions to the waterlines of basis ship respectively, the corresponding improved ship form is calculated.(2) Appending curved surface thin ship function to the curved surface of basis ship, the corresponding improved ship form is calculated.In order to calculate the wave resistance, this paper employs the tent function method which is proposed by C. C. Hsiung. The SUMT mixture penalty factor optimum method is used to calculate the offsets of improved ship forms.Using the tent function method, the wave resistance calculations are carried out for Y=(1—x~2) (1—z~4) math. Ship form and series 60, and in comparison with other calculation method for wave resistance.Taking both the above-mentioned ship forms as the basis ship forms, their improved ship forms are calculated and the corresponding theory improved ship forms are abtained.更多还原
