About Non-Autonomous Vibrations of Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2010)Non-linear vibrations of mechanical systems are described by differential equations of the second order, which are generally written .. . x f ( x, x,t ) 0 . In this work we study non-autonomous vibrations of mechanical ... -
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 ... -
Diagnostic of Structural integrity Using the Non-Linear Vibration
(Universitatea "Dunărea de Jos" din Galați, 2007)The aim of the work presented here was to investigate the possibility of using hangs in the non-linear vibration characteristics to detect damage in mechanical structure. The nonlinearities were detected by examining the ... -
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 ... -
The Analytical Exact Solutions of Non-Linear Differential Equations Which Describe the Parametric Free Vibrations of Mechanical Systems
(Universitatea "Dunărea de Jos' din Galați, 2010)The movements of many material systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the solutions of these equations. Although many concrete problems ... -
The Parametrical Free Vibrations of Elastic Systems, the Analytical Exact Solutions
(Universitatea "Dunărea de Jos" din Galați, 2012)The movements of many material systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the solutions of these equations. Although many concrete problems ...
