摘要: Abstract This paper studies the static and dynamic characteristics of 3-DOF aerostatic thrust bearings with orifice restrictor. The coupled perturbation Reynolds equations are solved simultaneously for first time to obtain stiffness damping coefficients considering interaction between these equations. mass flow rate is considered in determining numerical convergence solution. developed model demonstrates nonlinear relationship air film thickness pressure. effect thickness, tilt angles, rotating speed frequency ratio on load capacity, moments, volume rate, evaluated. results from provide guidance design bearing required performance.
