| 摘 要： | 介绍了基于阻力最小的小水线面双体船主尺度优化方法,引入逐步二次回归的优化思想,结合可变误差多面体算法和乘子法,形成了独特的优化算法.开发了阻力计算和主尺度优化程序(SWATHRES和SWATHOPT),根据输入的主尺度及优化变量约束,程序内确定给定几何表达的主体和支柱船型,在指定的设计航速下,计算输出阻力最小的优化船型及相应的阻力曲线.计算表明:该系统可用于SWATH阻力预报和方案设计阶段的主尺度选型.

| Abstract: | An optimization method and program is introduced,which optimizes small waterline twin hull(SWATH) ship geometry and results in a minimum resistance and an effective horsepower(EHP) for a speci-fied speed of the ship.Importing Twice Regressive idea to traditional optimization method forms a special rithmetic.A program code of resistance prediction and principle dimension optimization(SWATHRES and SWATHOPT) were developed by input several main dimension design varibles and contraints;the shape of a strut and ... |
