Formula Frame Alternative Design According International Rules Requirements
Ondák, Lukáš ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This master thesis describes design of frame construction of Formula Student car. The objective was to reduce weight and increase the torsional stiffness against to last version of the car. Next objective was to prove advantages of alternative frame. This had been achieved by gradual transformation of standard design of frame to alternative with the usage of FSAE alternative frame rules. The weight was reduced by 20% and torsional stiffness was increased by 34% thanks to FEM simulation and sophisticated changes of alternative frame design.

Formula Student Tubular Frame Design
Ratiborský, Pavel ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis deals with the design of the tubular frame for the Formula Student car competition. The first part is a brief introduction to the competition and used variants of frames. The main part starts with a list of restrictions by the rules and other necessary installation components. The central part is devoted to the draft modifications and their assessment in terms of torsional stiffness by FEM analysis. The final section presents the resulting frame design with respect to the required properties. The work is concluded final evaluation.

Measurement of vehicle torsion stabilizer characteristics
Haratek, Marek ; Míša, Jiří (referee) ; Porteš, Petr (advisor)
This diploma thesis deals with the measurement of the torsion stabilizer characteristics. The beginning of the thesis explains the function of a torsion stabilizer in a vehicle and introduces various technical options of stabilization. Next part is focused on computational simulation of representative stabilizers. Next parts are devoted to proposition of measuring device for torsion stabilizers in the laboratory and execution of the experiment. In the final part multibody model is created to demonstrate achieved results.

Conceptual design of two-seat high performance car
Straka, Martin ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
is diploma thesis deals with design concept of two-seater sports car with the main focus on chassis torsional stiffness and axle kinematics. The main idea started with some paper sketches which were later transferred to the 3D model with all the main parts (engine, differential, driver etc.) using CATIA V5 design program. Then the torsional stiffness was counted using FEM software ANSYS 12.0. Finally the axis geometry during bump/rebump movement of the wheel was simulated in MBS system ADAMS 2007.

Formula Student Chassis Rear Part Design
Hajer, Václav ; Svída, David (referee) ; Ramík, Pavel (advisor)
This diploma thesis deals with description of the design of the rear of the vehicle structure of Formula Student processed by using a 3D CAD system. Formula have to fulfill all requirements Formula Student rules. The requirements and rules are given by building of engine and other considered engine components. The final version of the design of the rear part is assembled with the supplied front and the computational model is created to simulate the torsional stiffness of the FEM system. Another analysis model is created for a foreign supplied frame construction. Both of these frames are in terms of torsional stiffness evaluated and mutually compared. There are also mentioned selected Formula Student rules and overview of the formula frames and their overview.

Sandwich structure application on the formula car
Žídek, Tomáš ; Cejpek, Jakub (referee) ; Löffelmann, František (advisor)
The master thesis describes application of a sandwich construction for Formula Student car. It will replace the current tubular space frame according to FSAE rules. The introduction is focused on the information of international Formula Student competition, including TU Brno Racing Team. Then there are important rules for the construction of frames and composite monocoques. For the selected production technology are found strength properties of face sheets made of carbon and hybrid fibres. Another part of thesis deals with the design of the sandwich panel using analytical calculation to determine the bending stiffness. On the basis of these proposals are made three-point bending and shear tests. Using of FEM simulation is detected torsional stiffness of the tubular space frame and the monocoque concept from the proposed sandwich panels. The conclusion is devoted to a summary of the important information and possible monocoque manufacturing process.

Design of Formula Student Chassis
Děrda, Martin ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis focuses on proposing construction and manufacture plans of a hybrid frame chassis consisting of a tubular space frame and a monocoque made of composite materials. Next, it discusses the simulation of the chassis via FEM analysis and also measuring of its torsional stiffness. In the final part of the thesis, the frame is compared to its older predecessor, which is made solely of a tubular space frame, and its advantages and disadvantages are evaluated.

Formula Student Tubular Frame New Evolution Design
Slimařík, Dušan ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
Design of new evolution steel welded tubular frame specified for Formula Student series is the main goal of this thesis. In the first instance, type of frame designs is described. Next part of thesis is devote to rules, which must be respected in designing of new evolution of tubular frame. In main part, construction design and calculations of torsional stiffness using MKP analysis are mentioned. Interesting point of this work is located at penultimate part, which deals with preparation of tubular frame production. This is integral part of the construction process at all. Thesis ends with project summary.

Measurement of the torsional stiffness of the vehicle using a 3D scanner
Malchárek, Miroslav ; Ramík, Pavel (referee) ; Porteš, Petr (advisor)
This thesis deals with the measurement of the torsional stiffness of the frame using Tritop system. There is described development of the frame due to the complexity of torsional stiffness. Further there is outlined a brief overview of the types of measurement and the effect of torsional stiffness on the driving behavior of the vehicle. The aim of the work is to develop a method for measuring torsional stiffness of the vehicle Formula Student and from the results of repeated measurements to assess the accuracy and repeatability of measurements.
