Method for realizing design optimization of air thrust bearing by applying fluid network method

The invention discloses a method for realizing design optimization of an air thrust bearing by applying a fluid network method. The method comprises the following steps: splitting a to-be-optimized air thrust bearing structure into a plurality of different types of fluid elements; dividing the fluid elements into one-dimensional elements and CFD elements according to the characteristics of the split fluid elements; the one-dimensional element linearizes a flow heat transfer characteristic formula and then brings the linearized formula into the fluid network for calculation; the CFD element obtains a flow heat exchange characteristic curve of the CFD element through three-dimensional CFD simulation, and the flow heat exchange characteristic curve is loaded to a fluid network for calculation; a fluid network of the air thrust bearing is built through the successive connection relation between the fluid elements; loading boundary conditions to inlet and outlet elements of the air thrust bearing network; carrying
