基于ANSYS的碳纤维连续抽油杆作业车侧翻稳定性的有限元分析

摘要

The application of the continuous carbon fiber sucker rod pumping system is successful preliminarily in the oilfields of our country,and has shown great economic value to promote to large area. A continuous carbon fiber sucker rod busywork unit is devel-oped in which the sucker rod lifting (setting down)and the sucker rod coiling are driven separately. In order to prevent the busywork unit to roll,a math-model which included 242 nodes and 228 elements was set up for the finite element analysis (FEA),and solved by using ANSYS FEA software. By calculation and analysis,it is proved that the vehicle will not roll over in routine operation,and its o-verall structural design is reasonable. And this designed model has certain value to further research.%碳纤维连续抽油杆采油系统在我国油田的应用获得了初步的成功，并显示出其大面积推广的巨大经济价值。一种将杆柱起升（下放）与杆柱缠绕分别驱动的新型碳纤维连续抽油杆作业车被研制出来。为了防止该作业车侧翻，建立了由242个节点和228个单元组成的有限元分析数学模型，并用ANSYS通用有限元软件进行求解。经过计算和分析，得出该作业车正常工作时不会侧翻，该车整体结构设计是合理的。另外，所设计的数学模型有一定的使用价值和更深入研究的参考价值。
