Abstract: This paper describes a mathematical model and presents the dynamic analysis of a series-hybrid tracked tank driven by two electric motors, one devoted to propulsion (PM) and the other to steering (SM). A double differential mechanism is adopted to electrically produce the speed difference between the tracks required for skid steering. In this paper, this specific transmission is called Electro-Mechanical Transmission (EMT). The EMT model supports the steering motor control strategy definition and the electric motor size optimisation. Dynamic simulations applied to a 55 ton main battle tank are shown and discussed to validate the obtained results.
