【摘要】 介绍一种新的液压泵/液压马达特性曲线(等功率曲线、等效率曲线、综合特性曲线等)的绘制方法,即利用移动最小二乘法对液压泵/马达的特性曲线进行拟合。所得到的特性曲线具有拟合精度高、通用性强等特点。最后在MAT-LAB中编制程序并给出了曲线绘制实例。更多还原

【Abstract】 A new method of characteristic curve(e.g.power isogram,efficiency isogram, combination isogram etc.,) drawing for hydraulic pumps and hydraulic motors was introduced.This approach deals with the characteristic curve of hydraulic pumps and hydraulic motors using MLS.Compared with least square(LS),MLS has a high accuracy and large coverage.A curve drawing example compiled in MATLAB was given.更多还原
