The goal is achieved by measuring the amplitudes of the oscillations of the rotor. The drawing shows the implementation of the method. Bearings 1.2 are installed in the housing 3 on the springs 4 and serve as supports for the fpys 5 containing and sensors 6 movements of the rotor shaft 7. The method is carried out as follows. - 20 Sensors 6 measure the oscillation amplitudes of the rotor for bearings 1.2 in the steady state. Then, a load 5 is installed on the 31 rotor 7 and the amplitudes of the rotor oscillations are measured again in the same mode. The stiffness of the supports and the radial forces acting on them are determined from the difference in measured amplitudes and from the centrifugal force of the ° load 5. The application of the method makes it possible to increase the accuracy of measuring the radial forces acting on the rotor bearings, the claims of the method for determining the radial forces in the rotor bearings by measuring the amplitudes of oscillations with an additional load on the rotor and without a load, characterized in that in order to increase the accuracy of the path by changing the amplitude measurement location, the oscillation amplitudes of the rotor are measured.
