MATLAB在双作用叶片泵定子过渡曲线中的应用

Application of MATLAB to stator transition curve of double action vane pump

双作用叶片泵定子过渡曲线对叶片泵的各项性能都有重要影响.高次曲线凭借其优越性能,常被选作定子过渡曲线,但高次曲线方程比较复杂,如何绘制曲线是个难题.运用MATLAB强大的绘图功能,通过编辑高次曲线(5次、6次)方程,并通过debug运行之后即可绘制出双作用叶片泵定子的过渡曲线,同时可方便地列出各极角对应的极径,对双作用叶片泵定子过渡曲线的设计及检验都有一定的参考价值.

The stator transition curve of double action vane pump has a major impact on its diversified performance. High-power curve is often chosen as the stator transition curve because of its superior performance. But its equation is complicated and it is a difficult to draw it. Resort to MATLAB＇ s powerful graphics capabilities by editing high-power curve （5th power, 6th power） equation and run it through debug to draw the stator＇ s transition curve of double action vane pump accurately. At the same time it can be very convenient to set out the radius opposite the angle. And all these provide some advices for stator transition curve＇s design and inspection.
