摘要
如何精确地绘制和应用特性曲线对生产产家和用户都有十分重要的实际意义。针对传统特性曲线绘制方法的不足,提出了用ANN拟合离心式水泵特性曲线以提高特性曲线绘制精度,解决数值泛化等问题的新方法。通过应用BP网络对特性曲线的拟合研究,对应用ANN拟合特性曲线的方法、特点等进行了分析。
It is very important for the manufacturers and users to draw accurately and apply the characteristics curve. To counter the shortage of draw method of traditional characteristics curve, this paper puts forward a fit method of characteristics curve of centrifugal pump based on ANN, to increase the draw accuracy of characteristics curve and to solve the problem of value generality. On the basis of the study on the fit of characteristics curve by BP network, this paper analyzes the method and characteristics of applying ANN-based fit characteristics curve.
