Abstract: The viability of the patented E-TRAN electric roadway and vehicle concept was examined from an engineering systems point of view. Specific recommendations are made regarding the end-usage and development of the propulsion concept. Based on this study, two research areas were identified and investigated in more detail: (1) quantify the auxiliary power needs due to power input discontinuities and (2) the dynamic effects of road pantograph bounce. Auxiliary power needs arise of power input discontinuities, either due to: (1) power strip segment failures, (2) lane changing, and/or (3) E-TRAN grid discontinuities, which includes getting the vehicle to and from the grid. Simulation results indicate that power strip segment failures will have the least effect on system performance. E-TRAN grid dicontinuities will have serious effects on the system while the effects of lane changing will affect performance at a level in between the other two. The dynamic effects of a road pantograph in contact with a road mounted power strip was also studied, first using simulated models and then verified by experiment. From a mechanical point of view, key issues that affect the design include friction, wear and dynamic bounce effects. Since good correspondence was achieved between the experimentally measured andmore » simulated support forces and pantograph angular displacement, the models can be used for future design analysis.« less
