摘要
根据机械系统动力学原理，建立了宽带长冲程抽油机系统运动微分方程和动力学方程。采用几何法分段求解动力学微分方程组，由编制的相应计算机程序确定出抽油机在一周期内的运动参数与动力参数变化规律，为合理选择电动机、设计机械换向装置及平衡重缓冲装置提供了理论依据。
According to the dynamic principle of mechanica1 system, the motion differential equation and dynamic equation fora load belt long stroke pumping unit system are established. The dynamic differential equations set is solved by the geo-metric method, and the variation patterns of the motion parameters and dynamic parameters of the unit in a period are de-termined by means of the relevant computer program, and this porovides a basis for the basis for the rational selection of the electricmotor, the design of the mechanical reversing device and the counterbalance buffer.
