ABSTRACT:
In a bearing mounting for flexible rotors there are provided bearing heads for the journals of the flexible rotors and a foundation to support such bearing heads. For the purpose to influence the natural frequency of the combined system rotor - rotor support which is dependent also on the support stiffness it is desirable to change the support stiffness in the simplest possible manner in such a way that starting from the effects of the flexible rotor to be treated on the signal pick-ups, a control and/or closed loop control of counter-effects is possible to find the balancing quality of a flexible rotor independent of the present support stiffness.
