Abstract

In this work the stability analysis of an aerostatic spindle is carried out. The linearized perturbation method is employed to calculate the stiffness and damping coefficients of the journal bearings. These coefficients are then used to perform the linearized stability analysis, which is compared with a non-linear analysis. In order to validate the model, the numerical rotor unbalance response is compared with the experimental measurements.
