The identification of bushings dynamics is crucial for the development of innovative model-based digital tools, such as for example predictive maintenance or virtual sensing. Quite a few nonlinear modelling techniques have been proposed over the years, which can be suitably used to develop advanced models that capture the linear and nonlinear dynamics of a vast range of mechanical components and materials. Despite this, the experimental identification of bushings dynamics is usually accomplished with the so-called Dynamic Mechanical Analysis (DMA). This technique involves complex measurements based on several time-harmonic tests with different frequencies and amplitudes.
