Analysis of flexible air bearing and design of testing machine

The paper takes a type of flexible air bearing as the research object, and the bearing structure is analyzed in detail. Combined with the traditional analysis method of tilting pad bearing and the fluid-solid coupling theory, a new analysis model for performance prediction of the bearing was established. The performance of air bearing with inner diameter of 70mm was calculated by changing the input pressure or the inlet capillary diameter. The structure of the bearing was optimized by analyzing the calculation results, and the structure of the separate inlet nozzle was added. A bearing testing machine is designed for the flexible air bearing test to verify the improvement of bearing performance.
