VIBROISOLATORS APPLICATION FOR DAMPING VIBRATIONS IN INDUSTRIAL FANS

Abstract eng:
In this work, authors taking into consideration some aspects connected with using vibroisolators for vibrations damping of simple rotor systems. The good example of such applications are industrial fans. In these machines forces of inertial character triggered by rotor unbalancing acting on hardly rigid structure, exciting oscillations with high amplitudes. Fans, as elements of given technological paths, must have to control possibility of air volume flow rate. This aim is obtained by changing of rotor rotational speed. In practice, that excitation frequencies are in wide band from several to a few dozen hertz. These conditions must be known and taken into consideration during design of vibroisolation systems for it proper efficiency assurance.
