FEM Simulation Analysis of a New-Style Slick Pole Self-Lock Up-Down Setting

Abstract

A new-style slick pole self-lock up-down setting is designed to realize large size up-down of crossbeam, its principle is that crossbeam’s “limitless” pass is realized by alternate motion of an overtop elastic cannula and a ringent elastic cannula connected with poles. FEM is used to calculate proper interference value to guarantee that elastic cover can move freely when it is pressed and it can be locked when it isn’t pressed. A new-style slick pole self-lock up-down setting’s design is based on it. Simulation analysis and practical application shows that this method is feasible.
