Construction of equipment for thin walled L-profiles instability testing
Polčák, Marek ; Vaněk, František (referee) ; Horák, Marek (advisor)
Bachelor’s thesis deals with the loss of stability of axially loaded thin-walled aluminium profi-les, which make up an important part in the aircraft structures. The loss of their stability is tes-ted by the compression test, which is used to determine the buckling load. Compression test may be influenced by many factors, which are related to the fixing to the testing machine. The aim of the thesis is to design a fixture, which would fix a specimen to the testing machine and improve the results of the test.

Design of Data Acquisition Equipment IMC Fastening System in the Car
Černý, Martin ; Jeník, Radomír (referee) ; Ramík, Pavel (advisor)
Devices for measuring the dynamic load and vibration of certain parts of the bodywork or parts of other parts of the vehicle are made using accelerometers and measuring instruments IMC. It must be simply installed into the interior of the vehicle so that it is not necessary to remove any parts of the interior and to avoid damage to all parts of the interior. The preparation must also withstand the considerable dynamic load generated by the harder operation tests.

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.

Biological Signal Generator
Kadeřábek, Jan ; Čech, Petr (referee) ; Sekora, Jiří (advisor)
This semestral thesis describes signal EKG, it’s origin, evaluation and device for his generation. After identification with standard course of EKG signal, was such as signal created in program language Matlab. It’s consisting of 10 sinus courses, where each of them has it’s own frequence, start phase and amplitude. Each of this part of EKG signal is beat frequence variant. Rates of it’s durations and sizes were fixed from medicin literature. Such as created program were rewritten to program language C and is basic of main program, which control signal processor. Finally was propoused preparation, which will be generated this signal. Outcome of this thesis is teoretic treatise about signal EKG, created program for generation of this course include part control and machine doing realization of biological courses.

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.

Standardized procedure of the machine tool adjustment for change of the machined part type
Nedoma, Tomáš ; Tuna, Jaroslav (referee) ; Lošák, Petr (advisor)
The bachelor thesis at hand is dealing with standardized procedure of machine adjustment in process of machined rail type change in Bosch Diesel s.r.o. Jihlava. In the thesis, procedures of external adjustment of preparations that clamp workpieces into machining centers and overall procedure of machine adjustment are described. The elaborated standardized procedures are included in instruction manuals, which are used by workers of the company for machine adjustments. These “manuals” shall minimize occurrence of defective steps in the adjustment process and prevent their interchange. Mistakes based in incorrect procedure of the workers lead to prolongation of the time necessary for machine adjustment in process of change of machined type by up to hundreds of minutes per month. Bosch Diesel s.r.o. has adopted these instruction manuals and thanks to them shall save couple of tens of thousands euro per year.

On the production technology of a specific part
Kalina, Adam ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
This document describes the design of new production technology specific part in an engineering company. The specific part is manufactured on a machining center by milling method. To create model was used SolidWorks software and to create CNC program was used SolidCAM program. There is production process created with new and old technologies. There is a comparison of both technologies in conclusion.
