ROTOR TRAIN TORSIONAL MODE FREQUENCY TUNING APPARATUS

摘要

PROBLEM TO BE SOLVED: To solve the problem in which current processes of mass addition can affect stresses in a rotor or lead to unwanted lateral frequency changes.SOLUTION: A rotor train torsional mode frequency tuning apparatus includes: a first shaft 105 and a second shaft 108; a coupling 109 operably disposed between the first shaft 105 and the second shaft 108; and a coupling element 2 disposed at the coupling 109 and configured to adjust a frequency of a rotor train, which includes the first shaft 105, the second shaft 108 and the coupling 109, by a change in at least one of inertia and/or torsional stiffness in the rotor train.
