Torque Vectoring Implementation for Formula Student Monopost
Šimanský, Sebastian ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This work deals with the design and implementation of an algorithm for adaptive torque vectoring, which is specifically designed to enhance vehicle dynamics and stability. This algorithm manipulates the torques of each wheel based on the vehicle’s angular velocity, allowing for optimization of traction and improvement in agility and control. By utilizing adaptive control strategies, the algorithm automatically adjusts to changing conditions and vehicle characteristics, ensuring efficient torque distribution in various driving situations. The functionality of the algorithm is further demonstrated through simulations, and the required algorithm model is implemented on the main control unit of a Formula Student race car via automatic code generation. The final outcome includes testing on a physical race car and evaluating the algorithm’s contribution to vehicle dynamics.

Sandwich Insert Design of the Formula Student Monocoque
Velfl, Tomáš ; Šplíchal, Jan (referee) ; Löffelmann, František (advisor)
The bachelor thesis is devoted to the insert joints and wheel suspension attachments on the racing frame of a Formula Student vehicle. First, research was done to obtain the necessary knowledge on the subject. Then the external loads stressing the joints were experimentally and computationally determined. Before starting the actual design of the attachments, the effect of introducing local loads into the sandwich structure of the monocoque was investigated, firstly on small calibration samples. The first phase of testing was to verify the failure mechanisms, the interaction between the different components of the composite sandwich and to test different attachment designs using different materials. Based on the data obtained, the material libraries were refined, and computational models were developed and extended by parametrization. Thus, in the next step, the final designs of the individual suspension points meeting the predetermined objectives were iteratively created. During validation tests, the functionality of the design and sufficient oversizing were demonstrated. Technologies such as CT scanning were also used. The results were evaluated to determine further testing options and further improvements to the current solution.

Numerical modelling of the Formula student powertrain
Krmíček, Antonín ; Ušiak, Michal (referee) ; Šebela, Kamil (advisor)
This diploma thesis deals with system modelling of Formula Student powertrain unit. System models allow the interactions between the different parts of the powertrain to be tracked, allowing the components to be optimized for the desired drive cycle. A system model of the powertrain is built based on measured data or calculations of component parameters. This can predict limiting factors such as maximum available motor torque, component temperatures or battery discharge. The model is validated against runs on the test track. Furthermore, the model is modified to consider the changes expected in the next generation of the vehicle. It is assumed that the model will be used in the future not only for the design and optimization of powertrain components, but also for lap time simulations as part of a virtual vehicle model.

Design of geometric elements to improve the aerodynamics of the front wing of the formula student car
Šulík, Daniel ; Trusík, Vojtěch (referee) ; Štefan, David (advisor)
This master's thesis focuses on the design of a new front wing for Formula Student. The first chapter dissects basic aerodynamic concepts and principles utilized in wing aerodynamics design. The second chapter showcases front wing concepts from various Formula Student teams. The third chapter introduces the official regulations for Formula Student 2024, primarily focusing on vehicle aerodynamic devices. The fourth chapter presents iterative designs of front wings modelled in Creo 7.0. The fifth chapter explains the process of preparing the model for simulation and demonstrating how vehicle geometry is adjusted in the SpaceClaim environment. Furthermore, it elaborates on generating the computational mesh and setting boundary conditions for car simulations on straights and in cornering. The initialization process of the task and the computation itself are also explained. The sixth chapter evaluates the results from simulations. Aerodynamic values such as downforce and drag are analysed on the front wing. Changes in the vehicle's COP position and the velocity and pressure fields around the front wing are also monitored. Flow characteristics around the underfloor, whose aerodynamic efficiency depends on the front wing design, are analysed too. The seventh chapter explains the production process and composition of the front wing.

Control of PMSM drive Formula Student
Kavec, Matúš ; Kozovský, Matúš (referee) ; Veselý, Libor (advisor)
This thesis describes the basic function of a vector control of permanent magnet synchronous motors, the operation of a torque-maximizing algorithm that extracts the maximum torque from the current value. It further describes the operation of the field weakening algorithm that allows the motor to spin above a nominal speed. Characteristic curves for a motor with an embedded permanent magnets have been developed in this work. Based on these curves, the various algorithms required for the vector control were developed. The algorithms were created in the Simulink environment, which allows the model to be exported to HDL code and IP cores for a programmable gate array. Functional IP core blocks were connected in the Vivado environment to create the vector control. The resulting design used 49 digital signal processing modules.

CFD software calibration
Gego, Tomáš ; Zima, Martin (referee) ; Popela, Robert (advisor)
The objective of this thesis was to calibrate a CFD software for use on a Formula Student race car. The calibration is performed by comparing the experimental data from the measurement of a single element wing in a wind tunnel with the same case replicated in a CFD software, for which the optimization of settings of the meshing and solver is performed. The result is an evaluation of deviations of CFD by assessing aerodynamic characteristics such as downforce, drag, pressure distribution, separation and wake in freestream and ground effect. The results are processed into a graphical and text form for future use in the design of aerodynamic components.
