Abstract

The dynamics of a multi disk rotor contacting a non-rotating stator with many degrees of freedom is analyzed experimentally. For this task a test rig is built up and described in the paper. Experimental results for slow run-ups and run-downs as well as orbits and frequency spectra are presented showing synchronous motion as well as backward whirl motion. The results validate the applicability of models with many degrees of freedom for rotor and for stator. A forced modal decoupling method is applied to the MDOF system and demonstrates that in a limited rotation speed regime simple SDOF models for rotor-stator contact are able to sufficiently describe the experimentally observed dynamics.
