Abstract: This paper presents a nonlinear model to describe the bending behavior of a rotating shaft, based on the general theory of a bending bar. Justification for this theoretical model is provided ...

Abstract: This paper introduces a creative synthesis and analysis of stroke-increasing and force-balancing mechanisms for rod oil pumping units by using the systematic linkage technique. The corresponding ...

Abstract: Based on a conventional walking-beam pumping unit, a dual-beam pumping unit for increasing stroke and reducing force is presented, and an approach involving computer kinematic and dynamic simulation ...
