Suppression phenomena of resonant oscillations in a strongly nonlinear system with a geometrical clearance between a support and a beam by the use of additional asynchronous excitations are studied. By adding another excitation to the system together with the main excitation, new non-linear phenomena in which the primary resonance curves become unstable in certain intervals and system behaviors shift to nonresonant solutions with smaller amplitudes are found. The relationship between the additional excitation coefficient and the frequency region for effective suppression is investigated for three types of single-degree-of-freedom systems subjected to complex excitations such as parametric excitation and forcing excitation. The similarity of those suppression phenomena in the system is recognized. Then it is shown that the location and the width of the frequency interval of suppression can be easily controlled by changing the parameters of additional excitations. The physical explanation of such suppression phenomena is also revealed in the phase plane analysis.
