Abstract
This thesis summarizes the key points of an experimental research work carried out at Ducati Motor holding in the Racing Department.
The aim was to calculate the position of the center of gravity and the inertia tensor of components of the Desmosedici GP prototype. These data are of fundamental importance for understanding some phenomena related to vehicle dynamics and for optimizing the multibody model of the motorcycle in order to accurately predict performance. To achieve this goal, two machines were used, an advanced version of the common three-wire pendulum and a measuring machine that exploits the principle of the simple pendulum. The most important characteristics of the machines will be presented, the mathematical model will be described and both the calibration process and the measurement procedure will be illustrated. A work carried out in parallel involved the design of supports dedicated to the components, necessary for the correct success of the measurement on the trifilar pendulum. Finally, the results of the experimental tests are presented and analyzed.
