【Abstract】 The bifurcational behaviours as the system’s parameters vary in Duffing-Van der Pol system with nonlinear restoring and external excitations are investigated by using bifurcation theory and second-order averaging methods.We obtained the conditions of existence of harmonic solutions and their bifurcations.更多还原
