Abstract
A digital nonlinear synthetic inductance is incorporated into theresonant shunt circuit in order to effectively mitigate nonlinear vibrations. Thetuning of the nonlinear inductance is determined based on the principle ofsimilarity. The dynamic response is obtained using the harmonic balanced method(HBM). The vibration power flow characteristics of the nonlinear system with thenonlinear piezoelectric tuned vibration absorber (NPTVA) are analysed tounderstand the mechanism behind the vibration suppression provided by thenonlinear inductance shunt circuit. A comparison with the linear piezoelectrictuned vibration absorber (LPTVA) reveals that the proposed NPTVA exhibitsadaptability to the hardening phenomenon associated with nonlinear vibrations.Based on the power flow analysis, the surrogate model-based optimization isemployed to determine the circuit parameters resulting in improved vibrationperformance compared to the analytical approach. The optimization results revealthat as the excitation amplitude increases, the optimal values for nonlinearinductance also need to be increased.
