| description |
A substructure technique is proposed to account for energy harvesting in vehicle
suspension systems. In this study, two dynamic models are coupled: a classic
7-DOF full-car model and a 14-DOF double wishbone suspension model for a more
reliable approach to energy harvesting predictions. In this context, a disk of
piezoelectric material is introduced between the frame and the spring shock
absorber assembly of each wheel. Additionally, wasted energy caused by undesired
vibrations in the vehicle’s suspension system can be partially recovered
and converted into useful electric energy. The converted energy is predicted by
using a 14-DOF coupled substructure model, along with double wishbone suspension
elements. Moreover, an approach using a linear piezoelectric model is applied.
Simultaneous solution of the differential equations of motion for these dynamic
systems is performed in the time domain, considering a bump as the input mode.
Tests were conducted to obtain the responses of ceramic, polymer, and composite
piezoelectric materials, focusing on their energy harvesting and mechanical
strength. Despite the indication of the ceramic piezoelectric material’s
potential for energy harvesting from wasted vibrations in this study, the
composite piezoelectric material seems preferable due to its mechanical
strength. |
