Experimental Techniques for Rotordynamics Analysis

  • J. Tonnesen
Part of the International Centre for Mechanical Sciences book series (CISM, volume 297)


Experimental test rigs are described for:
  1. 1:

    identification of bearing parameters.

  2. 2:

    the influence of mass unbalance on a rotor’s instability threshold speed and the effect of adding external damping to the rotor-bearing system.
