MODAL UNCOUPLING OF DAMPED GYROSCOPIC SYSTEMS

摘要: Abstract A new approach for uncoupling the equations of motion typical rotordynamical systems is presented. The method does not neglect speed-dependent effects, such as gyroscopic and can be particularly valuable in controller design actively controlled rotors. In presence hysteretic type damping, resulting uncoupled come with an equivalent viscous a sense yielding same natural frequency decay rate. illustrated through three examples technical interest: Jeffcott rotor Stodola–Green rotor, small gas turbine. generated results demonstrate that developed correct straightforward.
