Price of the works in terms of investor
Chalupová, Hana ; Comorek,, Martin (referee) ; Marková, Leonora (advisor)
The aim of this bachelor thesis is to built the optimal price of the works in terms of investor. The compilation of construction cost of a family house considering the charges resulting from its usage. Two functional segments from the budget were chosen for creating an alternative solution including the costs assessment and the life cycle costs. Finally, the optimal variant of materials was chosen and the price was compiled.

Life cycle costs of residential building
Biolek, Vojtěch ; Marková, Leonora (referee) ; Nový, Martin (advisor)
The aim of this work is to introduce the topic "Life cycle costs for residential buildings" and a specific example to compare the real cost with the model, resulting in the operating phase of the life cycle of a building, using indicators BLCC. The paper also solved possible replacements for alternative materials selected functional components that can be positively or negatively affect other life cycle costs. These solutions can be used investor to invest in other phases of the life cycle of the building.

Testing of Vehicle Suspension Components
Šidla, František ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with issues related to testing car chassis components during development. Automobile transport is the most common type of long-distance transport. That's why vehicles are constantly evolving to provide the best possible performance. Increasing demands on consumers are being placed on vehicles because of the introduction of modern technologies. New technologies and concepts need to be thoroughly tested that they can be properly integrated into existing models. Test devices for determining the characteristics of the chassis are generally described here using specific examples of individual machines. Subsequently, the work clarifies the testing of the service life of individual parts of the chassis. The last part is devoted to the conceptual design of a simplified hydraulic device for testing coil springs. From the calculated characteristics, a hydraulic actuator and pump are selected from the relevant catalogues. In conclusion, the importance of car testing in development is summarized, individual types of testing are described and the readiness of test devices for the future is indicated.

Design of elongated right angle milling head for horizontal boring machine
Svoboda, Ondřej ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
This thesis deals with design of right-angled elongated milling head for horizontal boring machine of FERMAT production. The thesis includes a detailed research of milling heads, a description of the head´s basic components and certain commercially available head´s comparison. Design part is describe components description and the design. Calculations are focused on determinating of forces generated during machining, setting of loading spectrum and the power load calculating individual gears during machining. In the next part is calculation of the reactions in the spindle bearings included, the equivalent load and durability of spindle bearings, spindle deformation and spindle bearings optimum distance. The thesis also includes spindle strength calculation, horizontal and vertical shafts analysis, gears design with helical teeth and gear strength. The thesis describes the design of extended milling head and particular design nodes which is supplemented by the 3D model. In this thesis is also included a drawing of assembly and components.

Increasing the life of blanking punch by coating
Šplíchal, Jan ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
This Bachelor thesis presents possible methods for increasing the lifespan of cutting tools made of steel 19 436 designed for cutting stator and rotor plates made of silicon steel. These sheets are characterized by high hardness, which adversely affects the edges of the scissors. Experimental hardness measurement on delivered samples has verified the actual heat treatment on the surface and inside the scraper. The measured value 62 HRC corresponds to the input requirements. Based on the literature study, a combination of chemical – heat treatment and coating was chosen as the most appropriate method. In order to preserve the microstructure of the punch produced after the heat treatment, it was necessary to apply the coating by physical vapor deposition, which is characterized by low deposition temperatures. The FeinAl coating will be applied by cathodic arc deposition and is primarily designed to protect tools and cutting tools.

Criteria of multiaxial fatigue life
Bauer, David ; Slámečka, Karel (referee) ; Horníková, Jana (advisor)
This bachelor's thesis focuses on determination of lifetime of material under multiaxial cycle loading. This knowledge is important for a good design of the most machine parts. The thesis includes a short description of the proces of material fatigue, which is consequence of cyclic loading. It contains fatigue criteria for the case of uniaxial and multiaxial loading too. From a large number of multiaxial criteria are chosen energy-based and stress-based models.

Evaluation of an inspection program and overhauls for ZLIN 26 aircraft
Jančář, Milan ; Finda, Jindřich (referee) ; Augustin, Petr (advisor)
This bachelor´s thesis deals with ZLIN Z 26 Series Aircraft maintenance and repairs procedures. Even the name shows, that this theme is very demanding and extensive. My interest was to explain some maintenance procedures of these aircraft and offer changes of it. In the beginning of this thesis we can briefly learn history of the ZLIN Aircraft and particular Z 226 Series models. There are mentioned difference maintenance procedures, applicable on the planes thru the service life time. Inspection and overhaul procedures are described in details and for better understanding were attached drawings or photos. Following chapter deals with evaluation existing inspections and overhauls - maintenance – procedures. Optimization of the maintenance is part of the chapter fourth, where is described possible innovation of the maintenance check list. In the last, fifth chapter, of this thesis are mentioned possibilities of the ZLIN Aircraft life time prolongation, which is actually discussed because of some aircraft of this type series reached basic life time limit, without any serious fatigue airframe damages appears.

Life cycle of wooden structures
Pavlíková, Šárka ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
This thesis deals with comparing the costs of construction of the timber and classical walling system throughout their life cycle. The first part introduces the history of timber, wood as a building material, processing of wood for building purposes, construction of wooden buildings, durability, removal and recycling of wooden buildings. The second part evaluates the cost of building a family house from both types of material and also cost of living in both buildings since their creation until their licvidation.
