Abstract
Vibrational control is a novel technique introducing additive or multiplicative vibrations into the system parameters in order to shape suitably the response of a linear or non linear dynamical system. Usually there are available only some theoretical results. based on averaging techniques, that assure the existence ofa suitable vibrational control. Almost no quantitative results useful from an engineering point of view are avaiilable. With reference to a particular test case, the well known Duffing equation, the performance improvement obtained by non linear vibrational control is illustrated along with a conjecture on the design parameters that is substantiated by extensive simulation results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
