摘要
Lackenby于1950年发表的横剖面面积曲线形交函数是计算机辅助船舶设计进行母型船变换的一种有效方法。但该方法是一种近似解法,且使用时要凭设计者的经验选取参数,若参数选取不当,只有到变换工作结束时才能发现。本文给出了一种新解法,可以避免文献[2]解法的不足,并能对母型船变换可行性进行预测。本方法已付之实用。
The application of the function δ_x=c(1-x)(x+d) presented by H. Lackenby in 1950 is an effective method for the variational design of a parent hull form in the computer aided design of ships. But the results given by the solving process is an approximate solution which neglects the second order value. Meanwhile, the improper selection of parameter can only be discovered at the end of the whole variational process. This paper presents an exactly solving method of the above-mentioned function by which the variation of the parent hull form can be performed.
