VISUALISASI FENOMENA HARMONIS DAN CHAOS PADA GETARAN TERGANDENG BERBASIS KOMPUTASI NUMERIK RUNGE KUTTA

Research has been carried out on the visualization of harmonic and chaos phenomenont coupled vibration physcal case using Runge Kutta numerical computation method with aim applying first to fourth order obtain a second differential equation solution system, calculating displacement value objects fourth, obtained graph againts time in for states at certain step width values compare convergence from special analytical method. The which is classified as was quite difficulted solve analytically, so used it an alternative solution. results research showed that state system when motion each pendulum constant position respect form sinusoidal C1 = 40 N/m, C2 30 C 10 0 N/m chaotic represented by irregular pattern. In this case, found converged faster than third best 0,001. also smaller approximation average error avarage are , order.
