It is several years that the Mechanical Machines Labs., Prof. V. Cossalter director, has been involved in motorcycles dynamics, due to the studies and applications of mathematical methods able to better understand and explain motorcycles dynamic.
Tire behavior plays an important role in vehicle dynamics studies.
Quantity and quality of the results reach so far in simulations are able to predict motorcycles behavior, when geometrical characteristics, weight and tires properties change.
Unlucky, there are not enough bibliography, information and data about motorcycles tires properties; so data inputs for dynamic programs are not correct in quantity and quality.
Even using automotive tires data is not correct, due to the minor contact size of a motorcycle wheel respect a car wheel, and due to the high camber angles reachable by motorcycles wheel.
The target of this work is the analysis and the construction of a innovative Tyre Tester, different from the solution proposed by Delft University.
The Mechanical Machines Labs built the M.A.T.T. (Moving Arm Tire Tester), due to estimate contact forces acting between tyre and road surface, when slip angle, camber angle and vertical load change.
Data obtained by laboratory tests and results on tyre behaviour are listed.
