Design of a device for the analysis of hydraulic damper valves
Čupr, Martin ; Jeniš, Filip (referee) ; Macháček, Ondřej (advisor)
The bachelor thesis deals with the design of a device for a stand-alone hydraulic damper`s valve analysis. The main goal is to construct a jig, where the valve is firmly attached, so it can be exposed to high-pressure oil flow, simulating the real conditions in a damper. In this thesis, the valves of the two specific hydraulic dampers were chosen. The jig was designed to enable testing of these valves loaded by operating pressure up to 32 MPa. As the jig is universal, it allows testing of any similar-sized valves. Moreover, it provides the possibility to test two valves at the same time and analyse their cooperation. The jig presented in this thesis was designed for the development purposes. However, the same principle can be used as a control jig in serial manufacture. This approach enables to measure both the valve`s pressure drop and the current volumetric flow rate of oil. Consequently, all the main characteristics of the valve which are derived from these two quantities can be invetigated. When the cooperation of two valves is analysed, the ration between volumetric flow rates in each valve can be determined.

Bonding of composite materials in precise applications
Schubert, Vojtěch ; Zouhar, Jan (referee) ; Kupčák, Radim (advisor)
This work is focused on the bonding of composite materials. Related research dealing with technology of production and bonding of these materials was additionally conducted. Practical part of this thesis was set to find out what the optimal bond line thickness was for the bonding of the composites. Thus, the strength of single-lap joints (SLJ) in series of various bond line thicknesses was therein tested. A model of samples (and design of their production by wet lay-up) for the experiment is also provided in this thesis.

Measuring the flexibility of vehicle suspension components
Gadas, Petr ; Zháňal, Lubor (referee) ; Míša, Jiří (advisor)
This bachelor’s thesis describes suspension kinematics and elastokinematics of vehicle axles, contains the design and manufacturing method of a jig, designed to measure kinematic complience of each suspension assembly, and deals with the measuring process and data evaluation. The goal is to measure the stiffness behaviour of suspension components of a Formula Student car Dragon X and to assign it to a multi-body software suspension model, which will result in a more detailed vehicle model, to achieve simulations that are closer to reality.

Production of a Jig Using Rapid Prototyping Technology
Růžička, Jan ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The subject of this thesis is the design, modeling and manufacturing of complex shaped parts using modern additive technology Rapid Prototyping. The theoretical basis of the work is involved in Rapid Prototyping and CAD systems and their technology, terminology and basic terms. The analytical part is dedicated to the implementation of the design – construction of the model in parametrical software SolidWorks followed with a creation of the part using 3D printer uPrint working on Fused Deposition Modeling method. Conclusion of this work compares this method with CNC machining and evaluates which method is more efficient and more economical.

Precise bonding of composite materials
Tellinger, Adam ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis deals with the issue of bonding composite materials. The first part of the bachelor's thesis is focused on research into the production of composite materials and gluing technologies. The content of the practical part is the design of test specimens and a preparation for their bonding with subsequent production. Furthermore, verification of compliance with the required accuracy of bonded joints when using different adhesives using 3D measurements.

Front Axle of a High-performance Sports Car
Hrudík, Jan ; Blaťák, Ondřej (referee) ; Drápal, Lubomír (advisor)
Tato diplomová práce byla psána při studentské zahraniční stáži, pod záštitou Evropské Unie – program „ERASMUS Student Mobility for Placement“. Stáž byla absolvována mezi prosincem 2010 a květnem 2011 ve společnosti a.d.Tramontana, mající sídlo v Palau de Santa Eulália, Španělsko. Pro kompletní návrh podvozku a odpružení jakéhokoli vozidla je nezbytná znalost mnoha technických disciplín. Tato diplomová práce se zabývá dvěma z nich – odpružení a řízení. Nejprve je rozebrána teorie, na kterou se může navázat v praktické části práce. Velká pozornost byla věnována srozumitelnosti textu a názornosti obrázků, bez zbytečných detailů, avšak bez vynechání důležitého. Tuto práci je tedy možné užít jako prvního kroku před návrhem podvozku. V další části je popsáno, jak byla probraná teorie využita při návrhu řízení u skutečného vozu, přičemž největší pozornost je věnována Ackermannově teorii řízení a geometrii zabraňující samořízení při propružení. V závěrečných částech je pozornost věnována ukázce některých z každodenních činností v malosériové výrobě automobilů – jde o zjištění maximálně možného pohybu kola při propružení a proces výroby příčných trojúhelníkových ramen včetně návrhu jejich připevnění k šasi.

Mobile Application for Easy Online School Education and Communication with Students
Otáhal, Lukáš ; Vlnas, Michal (referee) ; Chlubna, Tomáš (advisor)
The aim of the work is to create a supporting mobile application for students and teachers, enhanced with capabilities that are not yet available in existing school applications on the market. There will be 2 views in the app according to the login. A view for the student and a view for the teacher. The app is designed with an emphasis on simplicity and user friendliness. The app offers options such as writing and grading tests, viewing study materials, assigning or viewing assignments, viewing school news or school events, schedule overview, class overview and detailed student information with classification. The new school app is built using the Jigx platform and the data is stored in an AzureSQL database.
