Forced Vibration on Non-linear System

[square173205]

Usually a periodic force is used for the forced vibration. However when the potential is not harmonic, we often get insufficient amplification by the periodic force. In that case the aperiodic pulse excitation might be effective. I tried to simulate how the non-linear oscillator is excited by pulsed external force in the follwoing site;

you really need to stop linking to other sites. its considered bad etiquette.
