| Abstract: | The frame of Model LDCJ14-6 chain-drive pumping unit is analyzed with finite element method by means of SAPS program. The optimum design scheme is selected among 12 kinds of frame patterns step by step. Firstly, the force on the pumping unit frame is analyzed and a mechanical model is set up. Then the strength and rigidity of the frame are calculated with the space finite element method. And the optimum design scheme is selected at last by changing the section size and geometry location of the main rod components of the frame. The strength and rigidity and reliability of the optimum sought frame satisfy the operation requirements and its total weight is correspondingly lighter. |
