Cornering Stability and Dynamic Analysis of a Four Steering Wheels Vehicle Driven by “In Wheel” Engines

The paper describes the dynamic analysis of an innovative vehicle driven by two "in wheel" brushless motors and provided with four steering wheels. Such electric car has been designed for an academic competition where different trials have to be passed: for this purpose a deep investigation on the dynamic behaviour of both the suspended and the heavy unsuspended masses has been performed. A multibody analysis allowed to evaluate the vehicle's cornering stability and the vibration level induced on motors' parts, in order to prevent the detachment of the permanent magnets glued onto the spinning rotor. A particular attention has been paid to the design of car's suspensions
