Formula Car Rear Wheel Carrier Analysis
Oravec, Peter ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
This diploma thesis is focused on Formula Student upright analysis using final element method. The main goal is to review an effect of different boundary conditions on stress and deformation. Nowadays, the topologic optimization is a commonly used tool for design process of the upright, to create the lightest and the most rigid design possible. Boundary conditions, which should approximate reality really well, are one of inputs to topological optimization.

Design of Formula Student Car Wheel Carriers
Chlud, Martin ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
Master’s thesis focused on design and construction of front uprights for Formula Student racing car. Topology optimization and FEM analysis will be used to design the uprights with higher stiffness and minimal weight difference compared to the last model. In the FEM analysis loads will be applied from wheel side and from suspension side. Design of the upright then will be compared to the previous designs especially to safety factor, weight and cost.

Conversion of Car Front Suspension
Chaura, Václav ; Porteš, Petr (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis is focused on the design of the conversion of the car front suspension for racing purpose. Existing suspension solution is described by analyse static and kinematic quantities. Furthermore, a change of suspension is proposed to improve the driving characteristics of the vehicle, where the kinematic, dynamic and strength analysis of the newly designed suspension is performed. The conclusion summarizes the comparison of the original and the new suspension design.

Vehicle Front Wheel Carrier Behaviour Analysis
Baxant, Roman ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
Master’s thesis is focused on a design of front uprights for Dragon 8 racing car of TU Brno Racing Formula Student team. This thesis follows up the bachelor’s thesis called “Race Car Front Wheel Carrier Design”. Discussion about team’s recent upright and component designs is followed by a model creation with use of topology optimization. Final geometry is simulated in FEA software. Design of the upright is then compared to the previous designs and also to its substitute produced with milling machining process.

Optimization of axle carier for formula student for SLM fabrication
Vaverka, Ondřej ; Růžička, Bronislav (referee) ; Koutný, Daniel (advisor)
This diploma thesis deals with design of axle carrier for Formula Student. The axle carrier is topologically optimized and additively manufactured with Selective Laser Melting technology. Material for its production is aluminium alloy AlSi10Mg, which has worse mechanical properties than commonly used high-strength alloys. Therefore the aim was, by using topology optimization, to design a component, which would have comparable properties with milled component. The stress strain analysis was carried out by the finite element method and maximum deformation and safety coef-ficients were acquired. The prototype was made and its dimensions were controlled by optical digitization, which proved accuracy of manufacturing. The strength calcu-lations were verified by special testing device and photogrammetry measurement. The load during the tests was 20 % higher than in the analysis and no limit state was observed. This verified its safety and functionality.

Design modification of the vehicle upright
Coufal, Jiří ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This master´s thesis deals with design modification of specific upright in response to exchange the caliper for non-series one. It focuses on the creation and subsequent adjustment of the 3D model based on obtained size and shape of real upright by using 3D scan. For the editing part is conducted the strength test by using FEM and the results are compared with the values of the original upright.

Stand-up power wheelchair
Juříček, Václav ; Maňas, Pavel (referee) ; Černý, Michal (advisor)
This thesis deals with the structural design and manufacture of special power wheelchair prototype in collaboration with company Brano. Remarkable feature of this wheelchair is the ability to pull its user to an upright position, offering the greater independence, self-sufficiency and medically positive impact on physical functions. The content of this thesis is devoted to a search of the current state of knowledge in the matter, structural analysis of complete wheelchair assembly with a detailed description of each component including the important calculations and analyzes, as well as a description of the wheelchair testing. The conclusion presents summarization of all the results in structural, technological and economic terms.
