Handling, control and modal beavhiour of electric “in wheel” engines for electric and hydrogen-fuel cells vehicles. Ground accidentality and reactions on the engine components and fuel cells stack

The current development of the conventional electric vehicles takes place simultaneously with the advances of fuel cells equipped prototypes: Small manufacturers benefit of the results coming from the large R&D investments on the hydrogen traction by world car leaders; on the other hand fuel cell technology can exploit an advanced development platform on which improving the technical solutions to be integrated in tomorrow vehicles. A meaningful example is the introduction of the high flux density in-wheel motors. The company Movincar company has been developing two innovative products based on this advanced technology and adopted CAE virtual prototyping and kineto-elastic tools for a quicker and more affordable development. The goal of current research is to point out the effects of the vibrations induced by mechanical or electromagnetic factors on the in-wheel motor solution. A similar analysis is to be performed in the vehicle’s chassis with special attention to the accumulators’ housings.
