Proces zavádění robotizace ve výrobě zásobníku tlaku pro vstřikovací systém common rail / Integration od robot in production of pressure tank for common rail systemKrejčí, Monika January 2020 (has links)
This diploma thesis is about integration process of assembly line automation on rail assembly. In the beginning is introduced Bosch Company, then follows up theoretical part about automation and assembly lines. After theoretical introduction continues description of current state of rail assembly and choice the best line for automation and its detailed description. After that, the work deals with finding of the best solution for line automation. Found solutions are evaluated using the decision matrix. After the best one of them is chosen. There is also calculation of investments, because the one of important conditions is, that payback period has to be less than two years. Next step is choice of the most suitable supplier and integrator, which can cope with all requirements. At the end of thesis is analysis of risks done and thanks to this, are potentials for improvement of workplace safety found.

Návrh olejového distribučního transformátoru / Design of oil distribution transformerMrajca, Miroslav January 2021 (has links)
This master thesis deals with the manufacturing process of oil distribution transformers. Firstly, the thesis devotes to the design arrangement of the magnetic circuit and its manufacturing technology. The procedure of cutting laminations for core and their building into the core. Subsequently, the thesis describes technologies used for manufacturing primary and secondary windings including procedures on winding machines. Then it deals with the production of the tank and the final assembly of the transformer into one unit. The next part of the thesis discusses the design procedure of the assigned distribution oil transformer with a numerical calculation while respecting the requirements of the standards. Finally, the costs of the material of the designed transformer are determined.

Numerical investigation of lateral behaviour of a large pile group supporting an LNG tankJones, Kimberly 30 August 2021 (has links)
Liquefied natural gas (LNG) storage tanks are often supported by very large pile groups (≥ 100 piles). As these superstructures tend to be located along coastal areas, there is often a high risk of extreme lateral loading caused by either seismic, flooding or hurricane activity. In many cases, the foundation design can be governed by the required lateral resistance. At present, the responses of large pile groups subjected to lateral loading are not well understood. Published guidance for design is premised upon experimental testing of smaller pile groups (< 25 piles), and no additional commentary is provided to advise the design for groups of a larger scale.
A typical approach for design of laterally loaded pile groups uses the beam on Winkler foundations method, where nonlinear p-y curves are reduced by a p-multiplier to account for the group effects. Alternatively, an average p-multiplier known as a group reduction factor (GRF) can be used. Chapter 1 details the study of using 3D continuum finite element (FE) models to measure the group effects in large pile groups using p-multipliers and GRF. Soil conditions, pile spacing, pile number, and pile head condition were varied to observe their effects. The study also looked at the effect of the circular configuration of pile groups used in LNG tank foundations. The design standards and prevailing methods were shown to overestimate trailing row p-multipliers for large pile groups, particularly with larger pile spacing. Based on the study data and published data, a predictive equation was proposed for estimating GRF of a laterally loaded large pile group.
In addition, geotechnical engineers tend to evaluate the lateral responses of pile groups regardless of the presence of superstructures. It is not known whether this approach is suited for large infrastructure such as LNG storage tanks and their respective foundations. Chapter 2 captures the results from 3D finite element (FE) models used to observe the integrated tank and piled foundation behaviour and evaluate whether the current design approach used in practice is suitable. In addition, changes to soil-foundation stiffness, including varying soil conditions and pile spacing, were made to observe their effects. The results found that the foundation responses in the integrated model varied significantly from models which only considered the foundation. It was also found that the amount of LNG in the tank, soil conditions, and pile spacing also affected the lateral pile responses, particularly the leading and trailing piles. / Graduate

Sdružený objekt ČOV / Combined cast-in-place structure of WTPHoloubek, Jan January 2014 (has links)
Master's thesis deal with the design and static analysis of supporting structures of main underground reinforced concrete tank located in Combined cast-in-place structure of WTP in Kořenec. The tank has dimensions of 9.5 x 9.5 m and the is divided into four sub-tanks by internal walls. Supporting structures, foundation slab, external and internal walls and ceiling slab, were verified for limit state design requirements for concrete members. Verification of serviceability limit state and crack control of width was made.

Štěrkové pilíře - význam klenbového efektu / Stone columns - importance of arch effectVanko, Peter January 2015 (has links)
The aim of the the thesis is to study the development of arch effect depending on the change of the various parameters such as grid of columns, height of embankments, material of embankment fill and material of columns. The first phase of work summarizes theoretical knowledges of stone columns and arch effect. The next phase deals with analysis of the effect of arch using numerical modeling. In the next part of the second phase circular tank based on stone columns will be modeled, where deformations and stress on columns will be monitored in changing constitutive model and applying substitute characteristics. Obtained results will be evaluated in conclusion.

Ochrana obce proti extravilánové vodě / Study of possibilities protection against rural zone waterMatějková, Jana January 2015 (has links)
The first part of this thesis deals with the surface runoff and countermeasures. This allows us to control the hydrological conditions in the basin. Methods of protection against soil surface runoff are mentioned. A separate chapter is focused on dry retention tanks. Aim of the second part of the thesis is to design specific measures in the village of Otaslavice to prevent external area water from flooding the village. This issue has been dealt with for the whole basin . The Guidelines for very small basin runoff calculation was used to evaluate the runoff there, hydro technical solution was assessed and designed using the HEC-RAS 4.1.0 and AutoCAD 2013.
