Abstract: Aerodynamic foil bearings are self-acting air lubricated plain bearings supported by elastic foil structure, the performances depend largely on foil structural characteristics. The establishment of accurate foil structural model is of great significance for predicting and analyzing the static and dynamic characteristics of the bearings as well as the dynamic rotor responses supported by the bearings. The research on mechanical modeling of different types of the bearings is summarized at home and abroad. It is found that the mechanical model of foil structure has experienced a development from simplification to elaboration and can solve the problem of multi-dimensional foil deformation distribution, internal Coulomb frictions and nonlinear foil stiffness under variable contact states. Through the combination of structural finite element method and numerical algorithm of contact mechanics, the bearings with complex foil structure and nonlinear contact constraints can be finely modeled, more accurate performance parameters of the bearings can be obtained by calculation. In addition, the mechanical modeling of the bearings considering the manufacturing errors of foil structure and lift off process of rotor is also a development direction.
