【摘要】 水电站露天式压力钢管设计中,传统的方法是用解析法或方案比较法确定各段管道的直径,前者不能确保所得管径序列为整体最优解,后者计算工作重大,本文介绍用迭代—动态规划法确定水电站露天式压力钢管最优管径的方法,及其 CAD 程序结构。更多还原

【Abstract】 The diameters of an exposed penstock of hydroplants are usually determinated with so-called economic diameter formulas or enumeration methods in penstook designs.In the former,the obtained diameter sequence can’t be assured of a optimal one.In the later,complicated calculations are needed espically much more sections are considered. An iterative programming procedure and flow chart is concerned in this paper,which can be used to decide the optimal diameter sequence of penstocks with CAD.更多还原
