The design and simulation of beam pumping unit

Based on beam pumping unit, an new method of design beam hanger to dynamic loading and simulation in ADAMS software is presented, and beam pumping unit´s structure and working principle are introduced in this paper first. Secondly, using the development function of macro command in ADAMS software, combining with the connect method of bushing and contact through theoretical analysis and calculation to develop beam hangers and managed to get the virtual prototype of beam pumping unit. Finally, using the function of spline to simulate the indicator diagram and loading into suspension point, making dynamic simulation in ADAMS software. The simulation results reflected the actual motion law of the horse head of beam pumping unit, proved the feasibility of the new modeling method and provided the theory base for further research.
