Mechanical Version of the CRONE Suspension

Abstract : This paper deals with an application of the non integer differentiation in vehicle suspension area: the CRONE suspension, French acronym of suspension ´a Comportement Robuste d'Ordre Non Entier. This suspension results from a traditional suspension system whose order 1 dashpot is replaced by a non-integer order dashpot. The different steps, from the concept to its practical realisation, are presented. A quarter-car model is used to illustrate the performances. The frequency and time responses, for various values of the vehicle load, reveal a great stability robustness: the resonsance in the frequency domain and the damping ratio in the time domain remain almost constant whatsoever the load variations are.
