模糊综合评判在评价喷头水力性能中的应用

Application of Fuzzy Comprehensive Evaluation in Sprinkler Performances

通常采用在某一工作压力下 ,喷头的射程、流量、均匀系数、喷灌强度、水滴打击强度等五个参数来描述喷头水力性能。本文提出应用模糊综合评判来评价喷头的水力性能。即把六大要素按一定的比例组合起来 ,用一个数值来表示喷头水力性能的好坏 ,而且 ,此数值越大 ,则水力性能越好。从而简化了喷头水力性能的评定。

This paper puts forward using the fuzzy evaluation to evaluate the hydraulic performances of sprinklers under six main effective factors of pressure, wetting radius, discharge, uniformity coefficient, application rate, and intensity of drop striking, from the theory the hydraulic performance of the sprinkler can be indicated in one value.
