Sono qui costruite e studiate le Map of Achievable Performance (MAP) di Guiggiani come strumento di analisi della prestazione di una moto in curva. Le MAP sono mappe di livello che considerano grandezze cinematiche e descrivono, tramite la loro forma e i loro confini, la performance e le proprietà di maneggevolezza del veicolo. Permettono così di confrontare diverse caratteristiche del veicolo, del setup e dei pneumatici utilizzati e facilitano la scelta della configurazione migliore.
A tal scopo è stato elaborato e validato un Bicycle Model (BM) in Matlab.

This thesis is merely performance-oriented, and it is a study of a new Vehicle Dynamics tool called Maps of Achievable Performance (MAPs) from Prof. Guiggiani’s research work. The aim is to develop a tool for turning performance that simplifies comparison between different bike setups.
The MAPs describe vehicle handling in various 2D-plots, and the shape of a MAP can give precious information about the behavior of a vehicle for an experienced observer. For better usability, one can define a physical quantity that is correlated to turning performance and draw the maximum performance curves on the MAPs. Said curves can be eventually used for comparison between two setups, in order to determine the fastest.
To perform this task, a bicycle model has been built in MATLAB environment and validated with ADAMS. All simulations are run in MATLAB. The physical quantity selected to measure turning performance is the component of acceleration that is normal to the trajectory.
The second task of the bicycle model is to simulate the understeering or oversteering behavior of the motorcycle. An insight of vehicle handling can be useful for setup optimization – and also not to compromise rider’s control of the bike.
