基于Pro/E的抽油机运动学分析

Movement characteristic analysis of pumping units based on Pro/E

对抽油机悬点做了运动学理论分析,得出悬点位移、速度和加速度计算公式。采用Pro/E软件的Mechanism模块对南阳二机石油装备(集团)有限公司生产的CYJY10—3—53HB型抽油机进行机构运动学仿真研究,得出抽油机悬点位移、速度和加速度随时间变化曲线。研究结果表明,这种抽油机1个冲程过程中,悬点速度时刻在发生变化,加速度也不断地跟随变化,运动规律复杂。从研究中可以看出,借助先进的计算机仿真技术,在抽油机开发初期就可对其结构进行优化,可大大缩短产品生产周期,降低成本。

Kinematics analysis of the polished rod of pumping units is made,and the formulas for calculating the displacement,speed and acceleration of the polished rod are obtained. Mechanism module of the Pro/E software is used to simulate the movement of Model CYJY10-3-53HB pumping unit,and the curves of displacement and speed and acceleration of the polished rod vs time are worked out.
