Drgania układu z niesymetryczną charakterystyką sprężystości przy parametrycznym i zewnętrznym wymuszeniu

In this work the vibrations were considered of the system of two degrees of freedom with nonlinear quadratic type elasticity and linear damping under the parametric excitation and simultaneous kinematic exertion. Analytical examinations were proceeded by the method of perturbation. The correctness of the results of analytical considerations and stability examination were proved by means of an analogue simulation.
