| Abstract: | In this paper, the performance of hydrostatic journal bearings in the state of two-dimensional flow is analyzed theoretically by using the finite element method, and a mathematical model is set up. Compared with the performance of journal bearings in the state of one-dimensional flow, the experimental results proved that the theory of two-dimensional flow can be used in a wide scope. On the basis of this theory, an optimal design of orifice compensated hydrostatic jonural bearings with hydrodynamic effects (temperature rise as an objective function) is worked out, and its experimental result is shown satisfactorily. |
