Riassunto analitico
The purpose of this thesis is to design an anti-roll bar system (as known as ARB) characterized by asymmetrical stiffness with respect to roll, to be mounted on a Dallara high performance formula car.
Dividing the entire world motorsport scenario into two different categories, we can observe the “European” vision in contrast to the “American” one. The former is characterized by tracks consisting of both left-hand and right-hand turns, while the latter very often features ovals with only left-hand corners.
Obviously, the morphology of the circuits deeply influences the design of the cars and their set-up. This is the reason why European race cars are usually “symmetrical”, in the sense that they have the left half of the car almost identical to the right half, while American race cars do not.
In this work, we have mixed the concepts by trying to reduce the lap time of a symmetrical ‘’European’’ high performance formula car on some circuits characterized by asymmetry in the type of corners.
The goal is to design an ARB that maximizes the performance of the cars on circuits where almost all right-hand turns are taken at high speed and almost all the left-hand turns are low speed turns, or vice versa.
I conclude by saying that: this solution could be used only in some particular circuits of the championship, the driver must be able to push an asymmetric car at its limit and the amount of asymmetry must be thoroughly studied to achieve the desired improvements. This job demonstrates the feasibility of a system that achieves a huge level of asymmetry but, to understand which is the useful range of asymmetry, some track or simulator testing sessions are required.
