Vibrational control presents some practical difficulties: lower limits on amplitude and frequency of vibrations are unknown, stabilising vibrations are not always acceptable from a practical point of view, time properties of responses are unpredictable, simple rules useful from an engineering point of view are not available. In this paper vibrational control drawbacks are addressed in order to overcome the practical difficulties and to obtain some simple rules useful in the design. As test cases two examples of non linear systems are dealt with: the Duffing equation with linear multiplicative vibrational control and the Rayleigh equation with additive AP-forcing vibrational control.

Abstract

Vibrational control presents some practical difficulties: lower limits on amplitude and frequency of vibrations are unknown, stabilising vibrations are not always acceptable from a practical point of view, time properties of responses are unpredictable, simple rules useful from an engineering point of view are not available. In this paper vibrational control drawbacks are addressed in order to overcome the practical difficulties and to obtain some simple rules useful in the design. As test cases two examples of non linear systems are dealt with: the Duffing equation with linear multiplicative vibrational control and the Rayleigh equation with additive AP-forcing vibrational control.
