Investigation of the steady state vibration of flexibly supported rigid rotors attenuated by a new controllable damping element
Original language description
Lateral vibration of rotors can be significantly reduced if damping devices are added to the coupling elements between the rotor and the stationary part. For this purpose a new semiactive damping element has been proposed. It works on the principle of squeezing two concentric films of classical oil and magnetorheological liquid, whose flow is sensitive on magnetic induction. The damping effect is controlled by the change of the electric current generating magnetic field. The computational simulations prove that the proposed damping element makes possible to extend the speed intervals, in which the rotors can be operated.
