摘　　要：将开放式伞形结构细化为8项径向和3项轴向基本参数,给出了爬电距离、形状因数和等效直径的参数化表达式,并讨论了每一项参数对后三者的影响。采用数学建模的方法,将伞形优化设计问题转化为多元函数求最值的问题进行了讨论。本文的研究内容可为伞形优化设计提供参考。The aerofoil sheds is refined into eight radial and three axial essential parameters,the expressions of creepage distance,form factor and effective diameter are given,and the influence on the latter three of each parameter is discussed. Using the mathematical modeling method,the problem of transforming the shed optimization design problem into the multivariate function to find the maximum value is discussed. The research of this article may provide reference for the optimization design of sheds.
