On the vibration of a rotating disk
Web15 de jan. de 2024 · Meanwhile, the disk-drum rotor vibration problem plays an essential role in aero-engine whole-body vibration. Therefore, it is necessary to study the coupling vibration of the rotating-flexible disk-drum structure, and the relative research results would be conducive to the design of the rotor system including cylindrical shells and plates. WebIn this work, a continuum model is proposed to simulate and interpret the coupling vibration characteristics of a rotating disk-beam system with the dovetail interfaces. The dovetail …
