摘　　要：图解法在工程计算中应用广泛,但常规的手工图解法存在绘制不精确、效率低和难以实现数值的自动求解的问题,介绍了一种基于MATLAB的计算机辅助图解法,编程实现了限压式变量叶片泵特性曲线的ABC曲线的自动生成,根据快速和工进工况得到已知点,自动生成与AB、BC的平行线,并摘取两线交点得到了限压式变量泵所需要的最大驱动功率值等参数。Graphic method is widely used in engineering calculations, but the conventional manual graphical method, there are drawing inaccurate, inefficient and difficult to achieve the automatic numerical solution of the problem, this paper presents a MATLAB-based computer-aided graphical method, a limited programming pressure type variable vane pump characteristic curve ABC curves generated automatically, according to work fast and get into the condition known point, automatically generated with AB, BC of parallel lines, and removal of the intersection of two lines has been limited pressure-type variable pump the maximum value of drive power required and other parameters.
