Coupled non-linear vibrations in multi-supported rotors founded on slide bearings
Abstract
A study is presented of mutual coupling of the lateral, torsional and axial vibrations in multi-supported rotors operating in the nonlinear range. The object of investigations is a 200 MW turbogenerator founded on seven slide bearings. Presented are the methods of modelling of rotor cracks. These defects were regarded as the reasons of generating the coupled forms of vibrations. The work contains trajectories and vibration spectra of the real objects, as well as the results of tuning the model to the operational data of the objects.
