摘　　要：根据蓝波-奥芬凯勒图谱,利用非线性最小二乘法对船舶剩余阻力曲线进行了曲线拟合,将得到的方程系数保存为文本文档,建立VB与文本文档的检索方法,开发出船舶剩余阻力系数的计算平台.根据界面中输入的船型参数,利用计算机在数据中进行检索、内插,从而达到直接计算剩余阻力系数的目的.通过计算实例与实验结果比较,计算结果的精度完全能够满足船舶动态仿真的需要.With regard to calculation of the ship＇s residuary resistance coefficient, a realization software based on the Lap-Keller chart is established. Firstly, the obtained data is reserved as ＂ ＊. txt＂ document and the channel between software and ＂ ＊ . txt＂ document is established for data reading. Secondly, Operation interface is built on Visual Basic 6.0 environment. According to the parameters entering from the interface, the coefficients talked above will be obtained by using computer searching and interpolation among the data that reserved in the ＂ ＊. txt＂ document. Finally, the illustrative examples show the effectiveness of the above-mentioned software.
