本文收集了1968年以来国内外二百三十余艘常规散装货船的实船资料,就其主要船型参数的规律作了初步探讨。并运用逐步回归分析方法,借助电算机的大量运算,选出“最优”回归方程,整理概括出了一组适合常规散装货船的、多变量的主要船型参数统计公式。并与国内外已发表的有关统计公式作了比较。本文提出的统计公式,由于计入的因素多,形式虽复杂,但精度较高,适于用电子计算机对船型参数进行初步估算。文中对大型散装货船主要船型参数发展的一般趋势也作了简要叙述。
This article collects the real ship data of more than 230 conventional bulk carriers at home and abroad since 1968 and makes a preliminary discussion on the rules of its main ship parameters. By means of stepwise regression analysis, the “optimal” regression equation is selected by means of a large number of computer operations. A set of statistics formulas of multivariable main types of ships suitable for conventional bulk carriers are summarized. It has also made comparisons with relevant statistical formulas published at home and abroad. The statistical formula proposed in this paper, due to many factors included in the form of complex, but high accuracy, suitable for computer-based preliminary estimates of ship parameters. The general trend of the development of main bulk parameters of large bulk carriers is also briefly described.
