WebFor special rotor systems, different kinds of methods should be applied. For example, when balancing the dual-rotor system of an aeroengine, if balancing the inner and outer rotors separately, the system unbalance would occur even if a single rotor has been balanced. Therefore, a specific balancing method should be developed for dual-rotor systems. WebAug 30, 2024 · A dual-rotor system with an intershaft bearing subjected to mass unbalance and base motions is established. Using Lagrange’s principle, equations of motion for dual-rotor system relative to moving base are derived.
