Having a powerful car is good. Being able to use it to its full potential is better. Vehicle Dynamics brings all the mechanical energy developed in LRT2 to life by allowing it to express itself in contact with the asphalt. This team works mainly on the communication between the human and the machine via various mechanical systems that can be operated from the cockpit.
Handiness and lightness are the watchwords here. In a more global vision within the EPFL Racing Team, this division is also concerned with the challenge of maximizing power transmission from the engine to the wheels.
What is the purpose of the Vehicle Dynamics division?
“To make the car race! “exclaimed Hugo Delesalle, head of this division. “We deal with braking systems, suspension, steering and wheel assemblies. “
This year, one of the objectives we are contributing to is to improve the power-to-weight ratio from the previous year, which was 2.75 hp/kg. Choosing lightweight materials is logical to meet this objective, but it is also a question of ensuring their rigidity or flexibility, to maintain good handling.
A high-performance car is one that can be driven at the highest possible speed, as often as possible. It requires a well thought out braking system to avoid overheating. The suspension’s ability to maintain the ground contact area provides better grip, which allows for late braking. Fine steering allows the rider to control the vehicle when cornering. Where there is good communication between man and machine, magic can happen.
The Vehicle Dynamics team is a prodigious performer, whether it is the communication between man and machine, or the harmonious distribution of energy to the members of the choir that is LRT2. This part of linguistics and music tells of the multidisciplinarity of this team, which is as tightly knit as our chassis, the subject of our next article.
