Periodic Solutions of Some Differential Equations that Show the Non-Linear Vibrations of the Mechanical Systems
(Universitatea "Dunarea de Jos" din Galați, 2009)Many phenomenons of mechanical nature possess non-linear vibrations, their mathematical forming operation leading to differential equations or to systems of differential non-linear equations. In this work it is shown ... -
About the Vibrations of the Mechanical Systems with Non-Linear Damping
(Universitatea "Dunarea de Jos" din Galați, 2009)This work will analyze the non-linear vibrations of the mechanical systems, actually the ones with non-linear damping. If we consider damping F( x,x ) x( k k x );k1,k2 R 2 = − 1 − 2 Î & & & then the differential ...
