Modeling of Oscillations of Beam Structure Containing Two Rotors With Parallel Axes of Rotation

Lots of different investigations are carried out in the rotor-dynamics area.Most of them refer to the process of the rotor design. The problem of dynamics of elastic structures of flying vehicles containing ready-made rotors requires is proper development. This issue considers the problem of dynamics of the elastic-beam structure containing two ready-made rotors with parallel axes of rotation. The problem is considered using the test gyroscopic model with 6 degrees of freedom. It is shown, that the model asymmetry affects its Campbell diagram. The issue presents the experimental results obtained during the resonance test of the beam structure containing two ready-made rotors. The obtained experimental results are verified by analysis of the beam calculation model carried out using the MSC.Nastran.Rotordynamics software.
