Konstrukční návrh a optimalizace konzoly přední hnané nápravy u traktoru / Design and optimization of tractor front drive axle console

Šincl, Josef January 2017 (has links)
The master thesis is about design and optimization of tractor front drive axle console. The first part, include the design of the new console geometry with respect of the surrounding area. After that is on the newly designed part performed a strain-stress analysis for three selected operating modes of the tractor, which have been defined based on critical operating situations. In thanks of the results of the individual states, the geometry of the component is adjusted according to meet the fatigue failure limit state. After inclusion of critical site modifications, the console design was subjected to design optimization in the ANSYS Workbench program to reduce the amount of material by 10%. The end of the work, is carried out the evaluation of these places and then the console control calculation.

Výroba konzoly odjehlovacího stroje / The production of the console deburring machines

Hlavinka, Martin January 2018 (has links)
This thesis submitted deals with the project of the change of the production of the semi-finished product of the console which is produced by casting from the cast iron ČSN 42 2420. The component forms the frame of the deburring machine with two electric motors with the gearbox. For the suggested production the method MAG of technology welding was chosen. Because of the given technology the new construction of the component was chosen. The welded product consists of eight parts burnt from heavy-walled sheet metals. The suggested material of the construction is steel S235JR and for welding the filler rod Weld G3Si1, diameter 1 mm is chosen. For the determination of the optimal parameters of welding the testing through the slap next to the skin weld (size a5) was made. Simultaneously with the testing the fracture areas and the weld root were examined. The suggested parameters of welding were used during the preparation of WPS. For the assembling of the component the operating schedule of welding is planned.

Budova autobusového terminálu - statické řešení / Bus terminal building - static analysis

Fišman, David January 2022 (has links)
The master's thesis deals with the construction and design solution of the bus terminal project in Liberec. The building consists of three floors with different functions. In terms of structural shape, the entire length of the building consists of a cross-section of a two-storey, asymmetrical cantilever suspended on both sides. The main load-bearing structure of the roof contributes along its entire circumference to the load-bearing capacity of the lower ceiling by a system of ties. The design was defined by a feasibility study of the project, which established the concept of the appearance of the structure. The main target of the thesis was to design the solution of the load-bearing structure and then perform static analysis, dimensioning and assessment by the method of limit states according to the corresponding ČSN EN. The solution of the construction consists mainly of reinforced concrete elements which are suitably combined with steel parts. Elements of reinforced concrete are designed as monolitic or prefabricated. For the most loaded two-sided cantilever was designed reinforced concrete variant and prestressed variant. The thesis was made in its extent in a BIM compatible design.

Parametrické CAD systémy a databáze součástí / Parametric CAD systems and parts database

Szoltys, Kryštof January 2009 (has links)
Autodesk Inventor is a full 3D CAD system. This system includes tools for working environment tool, component design tool including information data management and technical support. The target of the first part is to describe the most important new features brought by Autodesk Inventoru 2009 version. In of next chapters the work describes creation common iPart, which is basically different variants set (proportions, material …) of one entity, and preparation before correct publication to the content center, which is a virtual database of all iPart. Also there is presented how to create the content center, how to work with it and adjust data. The aim of work is then the creation database a stator and a rotor packet for the firm ATAS electromotor Náchod Inc. In the thesis there is described creation of the lamination as an iPart and their publication to the new content center.

Návrh konzoly přední nápravy Forterra / Design of Front Axle Carrier

Lorenc, Petr January 2008 (has links)
This thesis deals with construction proposal of front axle consoles for tractor Zetor Forterra. The aim of this work is to design and construct the 3D console model, which will be put through a solidity analysis. Based on this analysis the console will be optimized according to the solidity needs. The model proposal is realized in the software Pro/Engineer. Following strength calculations are realized in the software Pro/Mechanica.

Statické řešení nosné železobetonové konstrukce rodinné vily / Static solution of bearing RC structure family villa

Neužil, David January 2016 (has links)
Master thesis describes design of reinforced concrete structure for family villa. Building is situated to the slope. Only chosen parts of concrete structure was designed and checked for ultimate limit state. Building consist of basemen and two floors. Part of second floor is cantilevered. Cantilevered part was designed according to vertical deflection. Building foundation consist of waterproof slabs. Walls in contact with soil are considered as waterproof, as well.

Odpružení kabiny traktoru / Suspension of tractorcabin

Prokop, Aleš January 2010 (has links)
This Master's thesis deals with construction design suspension of tractor's cabin. At the very beginning there is an overview of different possibilities suspension from others producers. Afterwards there is my constructional working from selection variant of suspension to final project with all details. The another part of my thesis is strain-stress analysis of significant parts of construction and suggestion of comparing the method with the previous variant of suspension.

Montovaná železobetonová hala s jeřábovou dráhou / Prefabricated reinforced concrete hall

Jakubcová, Hana January 2022 (has links)
The main work of the diploma thesis is a draft and a static judgement of chosen horizontal and vertical parts of prefab hall with a crane runway. The chosen parts are the girder, the column, the bracing, the foundation beam, and the foundation pad. The model for gathering of intern forces is made by the program SCIA Engineer 18.1 with the use of a bar 3D model of the whole project. The parts were judged on the ultimate limit state. The prestressed girder was judged on the ultimate limit state and the serviceability limit state.

Kulturní stavba v jižním centru / Cultural building in the south centre

Matěnová Kocmanová, Eva January 2010 (has links)
Culture building in the South Centre In my master thesis I have made a proposal of a culture building – Art Gallery. My work was based upon my previous proposal of the surrounding parc, where the gallery is placed. This location is connected with new site of planned main trainstation. Urban role of this building is to create a conection between new multifunctional estates and older industrial building - viaduct. Southern part of the parc is profilled as a riverine forest and swamps in my project as it was there naturaly before. Placement of the gallery and its entrances was quite dificult, because of complicated urban situation. My solution of this problem was a integrated volume building with a console spanning towards the new estates eastewards. This determines clearly the entrance and relations with surroundings. The first floor is composed by spatial foyer with a information desk, book shop, cloakroom, caffetery and multifunctional hall. Skyline of Petrov can be percived by windows on the north. The centre of the gallery is a vertical comunication formed by simple monolytic helical stair. The enlightment is provide by drawn up skylight. A rest space in the second floor provides atypic vertical views of old town of Brno, parc and the cathedral. Two large exhibition rooms and art workshop complete the second floor. In the basement there are 39 car slots, storage, technical and manitenance rooms. The caffetery in the first floor can be reached even directly from the parc via foot bridge over the swamp. Every spring the snowdrops and snowflakes flower there. The constuction material is armoured concrete with wall system completed with pillars.
