大型水泵性能曲线拟合算法分析与实现

Analysis and Realization of Pump Performance Curve Fitting Algorithm

工程技术参数的数量关系能够反映工程及设备的各项状态,但是数量关系的运算是难点。本文以水利工程中的水泵性能参数为例,分析研究了计算参数间关系式的方法,通过Origin对多项式关系的拟合计算出函数的未知系数,并通过VB语言编写成可直接调用函数方程式的EXE可执行程序。

The quantitative relationship of engineering technical parameters can reflect the status of engineering and equipment, but the calculation of the quantitative relationship is difficult. This article takes the pump performance parameters in water conservancy projects as an example, analyzes and studies the method of calculating the relationship between the parameters, calculates the unknown coefficient of the function through the fitting of the polynomial relationship by Origin, and writes it in VB language to directly call the function equation EXE executable program.
