Finite element analysis of thin section angular contact bearings

For multi body contact deformation in coordination of thin section angular contact bearings's stiffness analysis , the axial stiffness characteristics research  take 71718 bearing as an example of the thin section angular contact bearings.

  According to the impact of unit size on the analysis results to determine the reasonable size of unit.

  Use the determined cell size to establish three-dimensional finite element model of 71718 bearings , and analyse the axial stiffness.

  Build the bearing axial stiffness testing platform,  using for the test of the 71718 axial stiffness.

  The comparison of the experimental results and the  analytical results shows  , using Hertz analytical solution calculation with larger error , the solution obtained by the finite element method with the actual test results within an error of 10%.
