摘　　要：运用有限元软件ANSYS建立了双井抽油机机架结构有限元模型,对该模型进行了静力分析,结果表明强度足够安全。同时利用该软件提供的线性及非线性屈曲分析方法,对机架结构进行了整体稳定性数值分析。结果表明,机架整体结构不会发生失稳破坏,而且非线性屈曲分析可以更准确地计算出结构的临界载荷。ANSYS software was used to establish a finite element model for a static force analysis,which indicated that the frame of the energy-saving dual well pumping unit is safe enough.A numerical calculation was conducted on the frame model by means of the linear and non-linear buckling analysis method of the ANSYS software.The result shows that the frame structure is stable and safe,the non-linear buckling analysis method is capable of providing a more accurate critical load.
