The Finite Element Analysis Of Lei-ring Applied To Upright Column For Hydraulic Support

摘要

In this paper, the finite element model of the lei-ring was established in ANSYS software, the sealing performance of hydraulic support column piston was analyzed. Also, the numerical simulation analysis was made of the impact of column working pressure on the sealing performance, and a series of the integrated equivalent stress and contact pressure images of sealing ring when working were got. From those images, the location most prone to failure can be concluded. All of work can provide a theoretical reference for the design and use of drum sealing ring used on hydraulic support upright column.
