Abstract: Using the threedimensional software ANSYS WorkBench for nonbeam pumping unit for dynamic analysis, the threedimensional finite element model of the pumping unit rack was established. To ensure that the system could be fully reflected in the dynamic analysis of the characteristics of its own force , firstly , the software prestress modal frame was used to analysis the pumping units static characteristic, and then the module was used on the rack's modal analysis, the rack's front nine natural frequencies and mode shapes were obtained. The results showed the Prestress had a little influence to the intrinsic characteristics of rack, and it could be neglected, and the rack structure affected the overall stability of the rack|through the analysis, changing the form and structure of the rack scantlings could improve the system's stability. Thereby the life of the rack was enhanced.

摘要:  利用三维软件 AN S Y SWo r k B e n c h对无游梁式抽油机进行了动态特性分析, 建立了抽油机机架三维有限元模型。为确保系统能够充分体现动态分析的特征, 考虑机架自身的受力情况, 首先运用该软件的p r e - s t r e s sm o d a l模块对抽油机架进行了静态特性分析, 然后利用 m o d a l模块对机架进行模态分析, 得到了机架的前九阶固有频率和振型。分析结果表明, 预应力对机架自身的固有特性影响不大, 可以不考虑预应力的影响; 机架的结构形式影响机架的整体稳定性, 可以通过改变机架结构的形式和构件尺寸提高系统的稳定性, 从而延长机架的使用寿命。
