Non-synchronous vibration and frequency lock-in in coupled structures
Original language description
The contribution is aimed at phenomenological modelling and analysis of basic properties of non-synchronous vibrations in chosen coupled structures. A van der Pol model is employed to simulate the aero-elastic interaction between rigid flexible body and fluid structure. Non-synchronous vibration, frequency lock-in along with hysteresis is captured in the main resonance area. Moreover, the model reveals sub-harmonic resonances accompanying with existence of unstable solutions and frequency lock-in.
