| Popis: | A variational problem for a gas journal bearing is considered in the one-dimensional formulation. The feature of the problem relates to the fact that an additional condition of gas exchange with the surrounding medium, namely, the Elrod-Burgdorfer condition, is used in the Reynolds equation. The system of necessary conditions of the extremum is qualitatively analyzed and, as a result, a computational procedure is constructed. An asymptotic relation between a solution of the variational problem considered and a solution of the problem when the pressure is specified on the boundaries of the region (“open profile”) is detected. The results are given over a wide parameter range. |
