Grid density of bearing model

From the static analysis, accuracy of  thin section angular contact  bearing's analysis resultsand  has a direct relationship with grid density.

  If the grid is too sparse,the error analysis results will be greater. Too close greatly increases the computational analysis of time.

  Before build the finite element model of miniature linear bearings ,we should adopt a simplified model for determining the density of grid ,then carry on the grid division of the bearing model by the determined grid density.
