Roof of the swimming pool
Pelikán, Adam ; Šopík, Leonard (referee) ; Stráský, Jiří (advisor)
This diploma thesis is about designing the structure of roof of swimming stadium. Three solutions are created - concrete arc with tie, steel truss slab and concrete pretensioned membrane. One choosed solution - concrete pretensioned membrane - is afterwards developed. In the beginning there are several designs of geometry fulfilling the requirements for given type of structure being created. In part of static calculation, the parametrical mathematical model in form of macro in APDL language for Ansys software has been created. Afterwards all the parameters (initial state of cables, level of pretension, dimensions of membrane and peripheral frame, etc.) has been optimized in order to the membrane be fulfilling criterias for ultimate limit state and serviceability limit state. Afterwards other selected parts of structure has been checked. On basis of designed geometry and design checks in static calculation the drawings of conctruction and designed parts has been created. In the end, the 3D model of the structure has been created in graphical software Rhinoceros. Then visualizations of structure in concstruction stages and after completion has been rendered.

Crane Stroke Mechanism
Vydra, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of crane stroke mechanism with lifting capacity of 12 500 kg. At the beginning is research of different design solutions, their comparison and finally selection of the most suitable conception. Before calculation part of each unit is short theoretical part, which brings basic information about issue, whose result in choice of product from catalogues. On the grounds of calculations, firstly hoist parts are chosen, such as rope, pulleys, rope drum and main units of crane mechanism – electric motor, gear box and brake with coupling. Final part deals with strength calculations of rope drum and drum shaft and design of his bearing housing. The practical part of the work are assembly drawings of crane stroke mechanism and rope drum weldment.

Electric winch for drilling wells
Volec, Martin ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis undertakes design of two speed electric winch for the headgear specified for the drilling of the water wells through the use of core technology with the loading capacity up to 1000 kgs. Thesis consists of the theoretical as well as the operational part. Theoretical part is occupied with the possibilities of the problem solving, calculates the main winch parameters. In the study the reasons for choices of the main parts of mechanism e.g. electromotor, transmission, winch and others are given. Generally the brief introduction into the problem is inserted in each chapter prior to the calculations. Operational part involves the drawing of the overall configuration and the cable drum setup.
