悬栅消能工均匀正交设计及投影寻踪回归试验研究

Experiment on uniform orthogonal design and projection pursuit regression of energy dissipator of suspension gird in stilling pool

为探讨消力池内悬栅消能工试验设计和研究方法,在设计流量Q=8.0 L/s条件下,对悬栅消能工最大水深的3个影响因子栅高hs、栅距bs、数量ns运用均匀正交试验设计,并用投影寻踪回归方法对试验数据结果进行PPR建模分析及计算机仿真优化,得到池内最大水深影响因子的排序是悬栅数量ns、栅距bs和栅高hs;当池内最大水深达优值18.233 cm时,影响因子的优化组合为栅高hs=9 cm、栅距bs=5 cm和ns=16。

In order to elementarilly discuss the experimental design and research method of energy dissipator of suspension gird in stilling pool,the paper used uniform orthogonal experiment to design 3 influence factors such as suspension gird high hs,suspended grid spacing bs and number ns of the maximum water depth in the condition of design flow of Q being 8. 0 L / s,and took projection pursuit regression method to carry out analysis of setting up model and computer simulation optimization. The results are that the first influence factor of the maximum water depth in suspended gird stilling pool is number ns,and followed by suspended grid spacing bs,the last is suspension gird high hs. When the maximum water depth reaches the value of 18. 233 cm in stilling pool,the optimum combination of influence factors is suspension gird high hs= 9cm,uspended grid spacing bs= 5cm and number ns= 16.
