Analysis of a Nonlinear Elastic Force in a Relatively Long Annular Seal and its Impact on the Dynamics of the Rotor

Article Preview

Abstract:

The authors have developed a method of calculating the non-linear elastic force that arises in the clearance seal of a finite length. The authors have analysed the force impact on the dynamics of the rotor of a centrifugal machine.
