The optimum path at Adria race track
|
The new Adria (near Rovigo - Italy) race track is 2700 meters long. With 8 turns connected by 4 straigth the circuit is technical and provides the right enviroment for motorcycle dynamic analisys.
Thanks to the track owners that give great importance to motorcycle and rider safety, tests have been made with a instrumented bike. The following quantities have been measured and recorded:
the steering torqe applied by the rider
the steering angle
the roll rate
the yaw rate
the pitch rate
the lateral acceleration
the longitudinbal acceleration
the vertical acceleration
the forward velocity
Recorded risults have been compared with the results obtained by the optima manouvre. This is a numerical algorithm, developed by MDRG, which allows to evaluate the lap time, ie the time taken to travel a lap from a ideal pilot, able to exploit the full potential of the motorcycle.
The figure below shows the optimum path. The results obtained can be helpfull for non skilled rider, that can improve his performance and knowledge of the track in a safer way.
The folling pictures show a comparison between the optima manouvre results and data recorded during a test session with three different riders:
Franco Zanardo, a track expert rider called by his friends "the professor",
Mauro Salvador, ph.d student with racing experience now involved in Alpe Adria Championship
Vittore Cossalter, expert in theory, quite in the practice
The first graphic shows the comparison between the speed of rider Salvador and the optima manouvre. Thanks to these resutls the rider can improve his performance during a lap.
The second figure shows the comparison between the behaviour of all the three riders in a turn of the Adria race track. The optima manouvre roll rate is bigger than all the riders. Salvador is the fastest and nearest to the optimum results while Cossalter is the safest..
The third picture shows the yaw rate in the narrow chicane of the circuit. Again the optimum rider is faster than all the other three real riders.
