Vehicle Dynamics
Sector of the EVolt Racing team - UFRPE responsible for the feasibility studies and aerodynamic designs of the fairing, wings and airfoils of the car in order to reduce wind drag and aerodynamic instability at low and high speeds for better performance. It also works on research, analysis and selection of innovative, efficient, light and lower cost materials for the construction of the seat, cockpit, chassis and fairing of the vehicle, following the requirements of the Formula SAE competition.
The aerodynamic set of EVolt Racing - UFRPE has a focus on drivability, emphasizing the distribution of the aerodynamic load throughout the set of the single-seater vehicle and meeting the geometric limits required by the FSAE. In composites, respecting the chemical properties of the materials, we developed through CAD SolidWorks the modeling of the prototype so that it is possible to explore all the concepts in order to execute a competitive fairing project, and also a seat aesthetically contained in the standards of the vehicle competition. formula type, which meets safety and ergonomic requirements and consequently improves performance.
Sector of the EVolt Racing - UFRPE team focused on the study and development of the car's suspension and steering system based on the ability to absorb impacts and mitigate irregularities in the ground under the vehicular dynamics. The performance of a car is not only linked to engine power, but also depends on good vehicle dynamics. This is the role of the suspension, which has the ability to mitigate the unevenness and discontinuities of the roadway and maintain contact between the tires and the ground, in addition to interconnecting the directional joints with the vehicle's wheels, transmitting movement to the tires. At the same time, the suspension must have the capacity to absorb the forces generated by the irregularities of the track in order to minimize the transmission of these forces to the chassis.
Sector of the EVolt Racing team - UFRPE responsible for the development of the system whose objective is to regulate the torque transmitted by the engine to the wheels through a pinion ratio coupled to the engine shaft and a crown coupled to the differential, in order to provide the vehicle's movement. with the least possible loss of energy, being also responsible for the development of the braking system aiming at the car's drivability and its safety in risky situations for the driver, following the requirements of using a double braking system for Formula SAE competition.
The vehicular transmission system is essential to promote the transfer of energy made available by the engine to the wheels and thus provide the car's movement. Also having the function of regulating the transmission of this energy in moments of braking and acceleration of the vehicle. The braking system is one of the most important and essential components for its safe and effective operation, functioning as a four-wheel mechanism to retard or completely stop the movement generated by the force applied by the vehicle's traction system.
Sector of the EVolt Racing team - UFRPE that works in the complete project of the car chassis and the impact attenuator. The chassis is one of the most important parts of the vehicle's structure, it keeps the car stabilized and is the platform on which the entire vehicle is assembled, coupling the floor, bodywork, body and components of the powertrain, suspension, brakes, batteries, and transmission systems. It directly influences the driver's safety, giving shape and support to the car, enabling the development of different aerodynamic designs, while the attenuator is a rigid component designed to absorb a possible impact or frontal collision of the vehicle.
In addition, in the event of a collision, the chassis has the function of absorbing impacts, protecting the driver of the vehicle. We at EVolt Racing - UFRPE use the tubular chassis, following the rules in force in the FSAE regulation on the use and treatment of steel, as well as its measurements and triangulations. In addition, this geometry format provides great versatility in the choice of equipment and materials, in addition to being light and having good torsional rigidity.
