A theoretical and experimental investigation into the use of elastomers as the energy storage element of a regnerative braking system for urban vehicles was carried out. This work included the design, fabrication, testing and evaluation of full-scale elastomeric units and of a complete small-scale system which simulates a vehicle. The long-term stress-relaxation of elastomers at large strains was investigated, and its effect on the decay of rated energy density estimated. Based primarily on experimental data, the energy savings of a vehicle operating over the EPA Urban Driving Cycle with such a system was predicted, and the economic break-even cost of the system estimated.
