摘　　要：介绍了抽油机动力学分析的发展现状,以及刚柔混合系统动力学研究的原理。对抽油机作刚体假设的动力学模型无法系统准确的表达动力学性能。以新型整体弯游梁式抽油机为研究对象,建立刚柔耦合动力学模型,研究了柔性体大范围运动和弹性变形运动之间的耦合机理,通过仿真模拟分析与现场数据采集的对比分析,验证了分析方法的有效性,为抽油机的优化设计提供了基础。结果表明,引入柔性体对系统动力学性能产生显著影响,对提高抽油机的稳定性和使用寿命具有重要意义。The development status of dynamics analysis for pumping unit is analyzed. The principle of rigid flexible system dynamics is introduced. Pumping unit is assumed rigid body dynamics model which cannot express the dynamic performauce of the system accurately. To model the overall bending tour beam pumping unit as the research object, the rigid flexible coupling dynamics model was established, and analyzed the flexible body motion and elastic deformation movement between the coupling mechanism, through simulation comparison of analysis and field data acquisition analysis, verifies the effectiveness analysis method, and provides a basis for the optimum design of the pumping unit. The results show that the introduction of flexible body has a significant effect on the dynamic performance of the system, which is of great significance for improving the stability and service life of the pumping unit.
