The Melnikov theorem is used to detect the conditions for possible occurrence of chaos. The results show that the domain of the appearance of chaos is enlarged as both amplitudes of modulated and unmodulated forces increase. The effect of these two amplitudes, when both frequencies of modulated and unmodulated forces are different, on bifurcation diagram and Poincar\u00e9 map is also investigated, in addition to the surface of Maximal Lyapunov exponent versus modulated and unmodulated parameters for suppressing chaos being shown. <\/jats:p>","DOI":"10.1142\/s0218127411029288","type":"journal-article","created":{"date-parts":[[2011,3,31]],"date-time":"2011-03-31T10:20:32Z","timestamp":1301566832000},"page":"1583-1593","source":"Crossref","is-referenced-by-count":14,"title":["HOMOCLINIC BIFURCATION AND CHAOS IN \u03a6<sup>6<\/sup>-RAYLEIGH OSCILLATOR WITH THREE WELLS DRIVEN BY AN AMPLITUDE MODULATED FORCE"],"prefix":"10.1142","volume":"21","author":[{"given":"M.
