| Abstract: | The formulas of eight dynamic performance coefficients for the inside and outside of the pad of a single bearing elastically supported by the pad are analyzed and deduced. The calculating method about these formulas is presented.The theoretical analyses and their results are close to the real condition because of considering many factors such as pad inertia and pivot friction in these formulas and quantifying the effect of the gas film outside the pad. In addition, the influences of many factors on the stability of the bearing-rotor system are analyzed by use of the model of single mass rotor. |
