Design of milling machine spindl
Betlach, Jakub ; Hrbáček, Jakub (referee) ; Blecha, Petr (advisor)
The aim of this bachelor’s thesis is the construction of the milling machine spindle. The first part includes research in the structural part of machine-tools spindles that are used currently. The first section also contains an overview of producers of machine-tools and their milling machines. The second part is focused on the design of the spindle according to selected parameters, including the necessary calculations. This thesis also includes spindle assembly drawing and 3D model created with Autodesk Inventor Professional 2011.

Stroke mechanism of crane trolley
Malár, Martin ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the stroke mechanism of the crane trolley, maximum weight of loads is 16 000 kg. The work is divided into two parts: a written part and a practical part. In the written part of this work there are the main dimensions of lift and control cable drum strength solved. The calculation is subject to quantities that are given by assignment. Choice of the electric motor, gearbox and follow-up control of the stroke speed according to customer requirements is discussed further. The second part includes production drawings, in which are included the total set of the stroke mechanism and other assemblies and production drawings.

Footbridge
Smělíková, Petra ; Puchner, Josef (referee) ; Sýkora, Karel (advisor)
The topic of my Bachelor's thesis is a static assessment of a bearing structure of a current footbridge which is also used for cycling. It is placed in Kunovice near Uherské Hradiště. The length of span is 28 meters. Its construction is solved as space framework with through-span. Main beam is truss structure with upper saddle flange. The height of beam in the middle of the span is 2.5 meters and above supports is 1.5 meters. The calculation is done either by hand or using calculation program Scia Engineer 2012.0.
