Dynamic Finite Element Analysis for Tapered Roller Bearings

Based on the finite element method of explicit dynamics and contact dynamics mechanics, a three dimensional solid finite element model was developed introducing physical elements for tapered roller bearing. The dynamic process numerical simulation of tapered roller bearing was carried out in ABAQUS. The vibration curves of the nodes on roller were drew. The changes of contact stress and contact stress distribution of rings, rollers and the cage in the process were analyzed. The results show it is basically consistent with the actual movement of rolling bearings.
