The performance of aerostatic spindle is significantly affected by the fluid-structure-thermal interaction (FSTI) between the air film, the solid structure and the temperature field of spindle system. In this study, a novel simulation model of aerostatic spindle system is proposed to investigate the FSTI of the aerostatic spindle system, by which the elastic deformation and the thermal deformation of solid component can be considered simultaneously to estimate the performance of aerostatic bearing. Besides, the variation of the performance of air bearing and the gravitational eccentricity of shaft during the temperature rising process can also be obtained, which provides insight into the FSTI phenomenon of aerostatic spindle. Finally, the accuracy of simulation results are verified by testing the time-varying temperature of aerostatic spindle system.
