Analysis of Lubricant State in Ultra High Speed Spindle Bearing by Multi-grid Method;

Numerical calculations of the thermal elastohydrodynamic lubrication of rolling bearing were done by using multi-grid method.

To solve these problems,based on multi-grid method,structure grid for nonlinear FEM and sliding surface grid for calculating safety factor were established separately.

For the particular structure of water-lubricated plastic alloy bearings,with cannelures and low elastic modulus of plastic alloy bushes,and for the complicated numerical calculation of elastohydrodynamic lubrication(EHL),the multilevel method was introduced into the EHL numerical calculation of water-lubricated plastic alloy bearings,and the numerical results were attained successfully.

Equations are scattered and accuracy effects are get by multilevel method.
