Vibration Analysis of a Flexible Rotating Beam Including a Mechanistic Hysteretic Contact
The dynamic and vibration behavior of a rotating flexible beam system including a nonlinear hysteretic contact is
studied in this paper. Euler-Bernoulli beam theory, together with Lagrang’s method is utilized to obtain the governing
equations of motion for the system. The finite element method is used as the discretization procedure for the flexible
cantilever beam, which can be considered a distributed parameter system. A micromechanical model for nonlinear
compression hysteresis of random fiber networks was developed and examined on the felt-covered contact interfaces in the
dynamic system. The obtained results confirms the efficacy of the contact model in terms of accuracy and keeping the
simulation time tractable.
