Research on static characteristics of elastic foil gas thrust bearing applied to aeronautical ACM

Abstract In air conditioning system for aircraft, cycle machine (ACM) is the flimsy core component, which impacted observably by performance and reliability of elastic foil air-dynamic pressure bearing. It's necessary to have research on static characteristics Based finite element analysis (FEA) theory, it’s clearly obtained that discretized fluid lubrication Reynolds equation dynamic bearing weighted residual method. Coupled with deformation calculated beam model, gas film thickness used work out iterative calculation. And then, known how basic parameters impact its characteristics. The result method in this paper, verified correct experiment data other relevant papers, appropriate be as guidance reference further application ACM.
