Experimental validation of the Carbone-Mangialardi-Mantriota model of continuously variable transmissions

Abstract

We present detailed experiments to validate the Carbone-Mangialardi-Mantriota model of continuously variable transmissions. Experimental tests were carried out in different working conditions for increasing values of the torque load. Steady-state conditions as well as shift manoeuvres were considered. A detailed comparison with the theoretical predictions of the Carbone-Mangialardi-Mantriota model shows good agreement with the experimental results. This is even more remarkable when it is considered that the Carbone-Mangialardi-Mantriota model is fully self-consistent and completely predictive. It does not need any parameter to be specifically tuned or measured. The results from the present research allows the Carbone-Mangialardi-Mantriota model to be definitely proposed as a very accurate and completely predictive model of the continuously variable transmission variator, and as a very promising tool to develop advanced real-time control of continuously variable transmissions for engineering applications.
