On the Vibrations of a Mass Linked by Two Nonlinear Springs with Quadratic and Third Order Polynomial Characteristics
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 2
Abstract
We study the equilibrium positions and their stability in the case of a mass linked by two nonlinear springs. These springs have polynomial characteristic of different orders; one of them is a quadratic one and the second is described by a third order polynomial. The complications that appear are as mainly caused by the degree of the equation which has to be solved and the fact that the second degree polynomial which describes the characteristic of the first spring is not an odd function. A numerical example concludes this paper.
