Vyjížděcí stůl hydraulického zapracovávacího lisu / Moving bolster of hydraulic try-out press

Kozelek, Petr January 2014 (has links)
This thesis deal with the construction proposal of the moving bolster hydraulic try-out press with roll-up cover the bottom cross beam. Hydraulic try-out press is used for testing dies. Moving bolster is used for remove of testing die from the working area of the press. Roll-up cover is designed to protect the bottom cross beam against damage and dirt snapping. Part of this thesis is design a railway track, design of driving mechanism, strength calculation of all functional components, design of welded frame and mechanism of the roll-up cover including safety cover. Designed device is detail proposed in the 3D software. The thesis contains drawing documentation assembly drawings movig bolster, mechanism of roll-up cover and welded frame consisting of welded and machined parts.

Štípací stroj na dřevo / Wood-splitting machine

Henzl, Lukáš January 2014 (has links)
The thesis describes the design of the wood-splitting machine including stress and check calculations and design of the hydraulic circuit. For structural design, it is necessary to choose the maximum dimensions of wooden logs, which have length 1,1 m and diameter 0,5 m and over. The machine structure is vertical. Another task of the thesis is a technical report of similar machines and the justification of the design concepts of splitting machine. In the thesis, there is elaborated an experiment on different types of wood splitters, stress analysis calculated by using finite element method and there is also drawn up technical parameters of wood.

Rám kočky 330 t mostového licího jeřábu / Frame of foundry trolley crane 330 t

Otevřel, Marek January 2015 (has links)
The topic of this diploma thesis is the frame of the foundry trolley crane 330/65/20t. The crane crab is used for handling with molten metal. The frame is analyzed by strength inspection and fatigue strength inspection. The process is according to ČSN EN 13001. The analyses are made by using finite element method on a beam and shell models. The diploma thesis was made in cooperation with the Královopolská a.s. company.

Návrh zdviže na palety / Design of elevator for pallets

Hájek, Lukáš January 2016 (has links)
The diploma thesis is focused on the construction design of elevator for pallets with car seats weighing 200 kg. This device is proposed for vertical transport of the load between two working positions which are separated by 6m. Part of the pallet hoist is a roller conveyor attached on a lifting frame. The roller conveyor allows loading and unloading pallets from the fixed roller conveyors in the lower and upper station. There are the functional calculations of important parts, strength control of traction belt and shaft of driving pulley drum. By FEM (Finite Element Method) is detected stress distribution of the lifting frame. Parts of the annex are the manufacturing drawings of the lifting frame, shaft of driving drum, the driving station and drawing of the whole assembly vertical conveyor. Furthermore, the timing diagram function for one cycle, risk analysis and FMEA.

Návrh konstrukčního uspořádání vozidla studentské formule / Student Formula Arrangement Design

Niesner, Martin January 2008 (has links)
The rules and specifications of competition Formula Student are the main guidelines at frame design of students' formula. This diploma work discusses frame safety and structural requirements and also requirements on mounting of engine, single axles, rear-axle differential, engine intake and exhaust system, fuel tank, control elements, and so on. In the final parts of this diploma work analysis of maximum state of stress in material of on-load frame is made and total frame torsional rigidity is calculated. Total frame torsional rigidity is compared with those of Formula Ford and with other variants of Formula Student.

Analýza ocelových přípojů při seismickém zatížení / Seismic Design of Structural Steel Connections

Sotulář, Jiří January 2017 (has links)
The thesis deals with the analysis and standard check of structural steel connections subjected to seismic loads. Analysis is based on a software solution and standard check is performed according to standard requirements and formulas. The first part deals with the theory of seismic load. There are described the general knowledges about the earthquake and the method of determining the effects of seismic loading on buildings according to the EN 1998-1. In the second part of the thesis is made design and check seismically loaded multi-storey steel building. Design is based on recommendations of the EN 1998-1 and some recommendations of research. In the third part is the analysis, verification and check of steel joints, which are contained in the structure designed in the second part of the thesis. On the basis results of analyses of indivudual connections are defined recommendations and requirements for the use and design structural steel connections subjected to seismic loads.

Lávka pro pěší / Footbridge

Blaška, Jan January 2017 (has links)
The subject of the final thesis is timber footbridge for pedestrians and cyclists over the Desna river in Loucna nad Desnou village. The length of the footbridge is 30 m, width 3 m and height is variable from 4 to 5 m. The footbridge is covered with roof inclination of 20° in transverse direction and the roof is arch in longitudinal direction. Roofing is metal sheet. The structure is three-dimensional truss consists of two truss connected by rafters, floor beams and by members of bracing. The 2D-truss consists of bottom chord, top arch chord and webs. There are end posts made of streel bracing frames. The material of structure is mostly glued laminated timber, then timber and steel. The steel is used for connectors and steel bracing frames.
