Abstract: The development of advanced electromechanical vehicle systems requires the consideration of multiple physical processes including electromagnetics, fluid flow, heat transfer, and structural mechanics. Accordingly, this paper presents a suite of simulation, optimisation, and design strategies that may be applied to the research and development of modern electric and hybrid-electric vehicles. These computational methods are illustrated through three examples that involve electric motors and electronic systems. Two and three-dimensional topology optimisation studies, parametric geometry sweeps, and multi-scale models are shown to inform unique designs prior to the fabrication and testing of advanced prototypes. It is expected that such computational techniques will have a significant impact on the development of highly efficient future ground transportation systems.
