摘要
应用Timoshenko梁轴模型分析了单螺杆泵抽油杆的动力学特性 ,根据Timoshenko梁轴模型的运动方程得出了单螺杆泵抽油杆柱运动方程的解。该分析方法可求出抽油杆作涡动时的变形 ,有效地了解抽油杆的动力特性。这种方法用于从理论上分析地面驱动式单螺杆泵抽油杆动力特性 ,还须进行实际验证。
Timoshenko's beam theory was applied to the research of dynamic characteristics of rod strings in screw pump. The deformation and the dynamic characteristics of whirling rod strings can be obtained efficiently by using this method. This method is new for theoretically analyzing the dynamic characteristics of rod strings in screw pump.
