Abstract: High speed bearings are key components for safe operation of high-speed train. There is a
close relationship between rolling contact behavior and the service life of roller bearing. A 3D virtual
model for high speed railway double row tapered roller bearing is established using automatic surface
to surface contact between minimum component, and a finite element analysis of dynamic contact
characteristics of the bearing under straight-line driving and minimum radius steering under
scheduled velocity is conducted respectively using ANSYS/LS-DYNA. Speed, acceleration of
bearing, load distribution of roller, time-history curve of contact element about second principal stress
and vibration of holder is studied. The results can serve as reference in design and construction of
high speed bearing.

Key words: dynamics, virtual model, ANSYS/LS-DYNA, high speed bearing
