在对游梁式抽油机－有杆泵系统进行动力学分析的基础上，根据机械系统的力学原理，将整个系统简化为一个等效动力学模型。计算悬点载荷考虑了抽油杆、抽油泵及悬点运动规律等实际情况，建立了一套递推公式，反映了抽油机与有杆泵系统之间的相互作用关系，提出了一种求超高转差率电动机驱动抽油机真实运动规律的新方法。应用本文介绍的方法能真实地反映机－泵系统之间的匹配关系，获得的运动真实，精度高，适用于各种有杆抽油设备的动力学分析。
Based on the dynamic analysis of the beam pumping unit-rod pump system, the whole system is simplified into an equivalent dynamic model according to the mechanical principle of the mechanical system. Computation of suspended load Considering the actual conditions of the sucker rod, sucker rod pump and the motion of the hanging point, a set of recursive formula was established to reflect the interaction between the sucker rod and rod pump system, and a A New Method for Seeking Real Movement Rule of Pumping Unit Driven by Super High Slip Motor. Application of the method described in this article can truly reflect the Matching between machine - pump system, the movement obtained real, high precision, suitable for a variety of sucker rod pumping equipment, dynamic analysis.
