| Popis: | The three-dimensional variational problem of the optimization of the microgeometry of a gas-lubricated bearing with respect to the maximum lift criterion is considered. The pressure field in the gas film is determined using the Dirichlet boundary-value problem for the gas lubrication Reynolds equation. The results of the numerical solution of the variational problem based on the consideration of the first variation of a functional are presented. The calculation results are presented for a wide range of the problem parameters. |
