Abstract:
The suspension system is an important component of a truck. It provides stability to the vehicle, maneuverability, and comfort. A lot of energy is dissipated through this system. In order to scavenge this dissipated energy, piezoelectric stacks can be installed in the system. One of the factors which significantly impacts the harvested power voltage is the location and connection type of the piezoelectric stack in the suspension system. The series connection between the suspension spring and the piezoelectric material has been preferred in this study for it will not affect the mechanical properties and performances of the system. The equivalent system stiffness is increased and the ride comfort is negatively affected in case of a parallel connection between the suspension spring and the piezoelectric stack. The equations of motion of the truck were derived. Harmonic excitation simulations have been run in the MATLAB Simulink software in order to assess the potential of the energy harvesting from truck suspension systems through piezoelectric stacks.
