| Abstract: | A mathematical model of complex vibrations for the cantilever Bernoulli-Euler beam in the XOZ plane constructed by the finite difference and finite element methods and the fourth-order Runge-Kutta method is presented.
We determined the critical value of the damping coefficient ɛ = 0.28, at which the system changes from the dissipative state
to conservative one, using the Morlet wavelet. The results of analyzing the frequency characteristics of the system are presented. |
