Hydrodynamic bearing is the main working assembly used for supporting the modem and large scale mill. The criterion about series of of structure design parameters of the type of hydrodynamic bearing has not referred domestically until now. The article introduces the working principle and basic design parameters and calculation equations of hydrodynamic bearing. The optimal results are compared with common results, discussed and analyzed. With increasing the speed and power in machine and the society development, the energy consumption become a critical problem. In the paper, composite algorithm and engineering models are applied. The general computer program written in VISUAL BASIC for the optimal design is worked out in detail with the “total power loss/load capacity” as objective function, subject to equality and inequality constraints. The optimal parameters for the hydrodynamic bearing are presented, and the results are discussed.The method seems to be very efficient in design.
