Rotordynamics involving axial rubbing against a disk Conference Paper uri icon

abstract

  • Test results are presented involving axial rubbing of a test rotor with an overhung disk to investigate test results cited by Den Hartog. Analysis of a nonslipping kinematic whirl condition (comparable to classical dry friction whipping) for the face of an overhung disk against a stationary surface predicts reverse asynchronous whirl; however, testing over a wide range of parameters failed to produce this response. None of the present test results produced the types of very high vibration levels and grave consequences that have been produced in test rigs for conventional, radial dry-friction whirl and whip.
