Stability of Nonlinear Mechanical System with two Degrees of Freedom

Svetoslav Nikolova, Julian Genovb, Nikola Nachevb

In this paper we investigate how the inclusion of nonlinear restoring force alters the stability properties of the two mass mechanical system. The consequences of a nonlinear restoring force on the stability of this system are analysed using Routh-Hurwitz criterion for stability. Our analytical calculations predict that nonlinear fragment acts as a key parameter. This is confirmed by numerical simulations
