A study is presented of matual coupling of the lateral, torsional and axial vibrations in multi-supported rotors operating in the non-linear 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.
