Travelling and lifting mechanism
Bernard, Vladislav ; Malach, František (referee) ; Malášek, Jiří (advisor)
The thesis deals the design and calculation of handling equipment designed for transport of Bell helicopter between the airport and hangar space. The first part contains an analysis of possible mechanisms applicable to the handling of the helicopter as well as an overview of the overall evaluation of some producers, engaged in the manufacture of this type of device. The second part presents the design, necessary calculations and drawing documentation. Handling equipment is designed for loading kapacity of 2000kg with a minimum 80 mm lift of helicopter to ensure safe transportation to the required distance.

Braking marks creation analysis in dependence of vehicle deceleration
Svoboda, Lukáš ; Panáček, Vladimír (referee) ; Vémola, Aleš (advisor)
The work is divided into two parts – theoretical and practical. The first, theoretical part is focused on introduction with the problematics, describing the concept of translation motion and brake physics, defining terms adhesion and friction, skid, driving resistances, calculation formulas etc. After the mechanics chapter follows the chapter about tire and its composition and properties, and a brake system chapter, describing Anti-lock brake system (ABS) and some other important brake-support systems. Second part of this thesis is focused on practical side, which contains acceleration measuring and skid marks creation, followed by evaluation of measured data in form of calculations and graphs.

Static solution of parking house
Rose, Dominik ; Koláček, Jan (referee) ; Zich, Miloš (advisor)
The bachelor's thesis is focused on the elaboration of a static solution of a parking house with four above-ground floors. Three variants are elaborated, one of which was elaborated in more detail. The proposed elements are the ceiling slab, the columns and staircase. The SCIA Engineer 20.0 program is used to calculate the internal forces. As part of the work, drawing documentation is also prepared. The structure is designed according to correctly valid standards.

Cross_section and reinforcement optimization of roof truss
Odvárka, Miroslav ; Šimůnek, Petr (referee) ; Laníková, Ivana (advisor)
The thesis is focused on optimization of cross-section shape of reinforced concrete truss. An optimization algorithm was created in Microsoft Office Excel which optimizes the shape and reinforcement of the reinforced concrete truss. The truss is as cheap as possible while complying with the ultimate limit state and serviceability limit state - deflection. The algorithm uses the Solver tool which is a supplement program Microsoft Office Excel. Two truss variants were created. One has a cross-sectional shape of a truss designed according to empirical relationships and the second comprises an optimized cross-sectional shape using the algorithm formed. The internal truss forces were detected using Scia Engineer. Both options were statically assessed. When comparing the variants, that a considerable part of the material cost can be saved when optimizing the cross-sectional shape.
