摘要
后驴头的型面对双驴头抽油机的性能有很大的影响,须进行优化设计才能实现精确平衡,达到节能降耗的目的。针对后驴头型面为阿基米德螺线的双驴头抽油机设计模型中复杂的超越方程解析求解的困难,结合MATLAB的函数,编制相应的M文件,给出一种数值分析方法,进行一阶导数和二阶导数的运算,从而进行抽油机运动分析和动力分析,完成优化设计。该数值分析方法简单易行,以差分代替微分运算,为双驴头抽油机的性能分析提供了数值分析手段。运算精度足以满足工程设计的要求。
The outline shape of rear horse head has enormous influencing on the performances of dual horse head pumping unite,so the optimal design may be made to obtain the outline shape of rear horse head. In this way accurate balance to dual horse head pumping unite can be obtained to achieve saving energy and reducing consumption. Because there was complex transcendental equation in the model which optimal design would be made in dual horse head pumping unite which the rear horse head outline shape was Archimedes spiral,so the analytical solution was difficult to obtain. In this paper, combining with MATLAB function to program M-file a numerical analysis method was given so that the first and second differential coefficient could be calculated easily, thus kinematic and dynamic analysis of pumping unite could down easily and so did optimal design. The numerical analysis method was simple and easy, by taking difference instead of differential the basis of numerical analysis method was given for performance analysis of dual horse head pumping u- nit, and computing precision was enough to meet the requirement of engineering design.
