Simulation, Design and Realisation of an entire Electrical Off-Road Motorbike

ABSTRACT This work presents the modeling, simulation, realization and validation of an entire electrical two-wheel off-road motorbike in cooperation between arsenal research and KTM-Sportmotorcycle AG. All components of the motorbike such as electrical machines, batteries, power train, etc., are implemented and modeled in the simulation environment Dymola, using Modelica programming language. The power train set of this electrical motorbike is founded on a battery powered electric traction machine and a transmission with only one gear and chain drive. The variation of type and size of the electrical sources and mechanical power train components is considered and explained. For the validation of the entire electrical motorbike simulation model, all electrical and mechanical components of the motorbike are measured. Based on the measuring of the electrical and mechanical motorbike components and the simulation results performed at arsenal research a prototype of the electrical motorbike is constructed and realized. The entire way from simulation, to optimization and the choice of the components to the realization of the electrical motorbike prototype will be explained. The motivation for electrifying an off-road motorbike is the reduction of the exhaust emissions to zero and furthermore a significant reduction of noise.
