Method and arrangement for the traversing of the critical rotational
speeds of elongate rotors
摘要:
A method and arrangement for the traversing of critical rotational speeds of elongate rotors. At least one critical frequency altering means in the form of springs, dampers and masses may be operatively connected, singly or in combination, to the rotor to thereby produce a change in the frequencies and/or amplitudes of the rotor, or in the critical rotational speeds and their amplitudes.
