| description | The main goal of this paper is to study, numerically and
experimentally, the effects of the bearing support flexibility on
the rotor dynamic and the first forward and backward critical
speeds. The test rig which is used in this study has been
developed and built at the École Centrale de Lyon (France).
This flexible rotor, supported by two rolling bearings on flexible
supports, is used for three configurations of the flexible
supports. The support characteristics are determined
experimentally by performing static tests. Moreover, a finite
element model of this flexible rotor is presented which consists
of a rigid disk on a flexible shaft supported by two bearing
supports. On the basis of measured frequency response functions
for various rotational speeds, eigenfrequencies and the associated
Campbell diagram from the numerical model and the related
experimental results for the flexible rotor are discussed. The
comparison of these experimental and numerical tests are used in
order to update the finite element model and the associated moment
stiffness of the two rolling bearings for the three configurations
of interest. |
