Abstract Multiple timescale effects can be reflected bursting oscillations in many classical nonlinear oscillators. In this work, we are concerned about the induced by two damped Helmholtz-Rayleigh-Duffing oscillator (written as DHRDO for short) excited slow-changing parametrical and external forcings. By using trigonometric function variation authenticating slow excitations a slowly varying state variable, time-varying rewritten new time-invariant system. Then, critical conditions of some typical bifurcations presented bifurcation theory. With help analyses, six patterns, i.e., ‘Hopf/Hopf-Hopf/Hopf’ bursting, ‘fold/Homoclinic-Hopf/Hopf’ ‘fold/Homoclinic/Hopf’ ‘Hopf/fold/Homoclinic/Hopf’ ‘Hopf/Homoclinic/Homoclinic/Hopf’ ‘Hopf/Homoclinic/Hopf-Hopf/Homoclinic/Hopf’ explored slow/fast decomposition method other techniques. Our findings provide different forms oscillation modes well patterns. addition, use numerical simulation to prove correctness theoretical analyses.
