CHAOTIC BEHAVIOR ANALYSIS OF DUFFING'S OSCILLATOR ON 2-BAR TRUSS STRUCTURE

Abstract

Dynamic bifurcation of numerical analysis for the nonlinear Duffing's equation of a simple elastic structure under the periodic force is presented. The aim of this research is to solve the chaotic solutions on a 2-bar truss structure with damping system, and it has a geometrical nonlinear stiffness on this model. It shows the view of the Poincare solutions caused by its geometrical nonlinearity by increasing parameters. It is possible numerically to solve Duffing's equation under the periodic load with a geometrical nonlinear stiffness. We show the chaos attractors for the force amplitude parameter and the circular frequency parameter.
