Finite element simulation of non- linear deformation behaviour in large diameter angular contact thrust bearing

摘要

The objective of the present study is to obtain relevant contact stiffness for a single ball-raceway contact which can be used in load distribution analysis of full bearing. Towards this, an elastic constitutive model is used in the 3D finite element analysis of load deformation characteristic of large diameter bearing ball - raceway contact and the finite element results are validated by conducting experiment on the linear mock up model bearing. The FE results show a good agreement with the values calculated using Hertz’s relations for deformation.
