Manufacturing of the turnbuckle of chain
Ondráček, Pavel ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The diploma thesis is focused on the design of the production technology of a chain tensioner. It is a spatial component made of 1.5 mm thick steel sheet with galvanized surface treatment. DC01 steel was selected as the most suitable material. When considering the production technologies, the production in a combined process tool was selected as the most efficient one for the series of 20,000 pieces. Regarding the tool of more complex design including springs, the production will be done in four steps on the LEN 63 eccentric press with accessories used for feeding and unwinding the metal sheet belt from the coil. The final price of the chain tensioner including the bolt and two nuts is 26 CZK.

The Project Proposal for Construction of Wind Turbines
Horák, Filip ; Ondráček, Pavel (referee) ; Doskočil, Radek (advisor)
This bachelor's thesis deals with a project proposal for construction of wind turbines. The first part is consisted of definitions of some basic terms of project management and also of description of methods, techniques and tools of project management, which represents theoretical backround for two following parts of the thesis. There is analyzed wind energy in Czech Republic and the company and its environment and gradually produced a plan of project as requested by a certain company. for supporting their decision-making process. The results of this thesis help other investors or public to understand the process of wind turbines construction.

Production of steel structures of halls
Ondráček, Pavel ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with the production of steel constructions of halls in a complex way. The introductory chapter introduces the advantages and disadvantages of steel constructions, their basic distribution, individual types of constructions and their parts. The following chapters describe the individual phase production of steel constructions of halls, from initial design and negotiations with the investor, through preparation of production, production itself, to final assembly. In the production process are described possible variants of the methods used. Description of the assembly procedure is complemented by the most common cover elements of the hall. The practical part describes the production and installation of a specific steel construction in a selected production plant. The part of the bachelor´s thesis is also the issue of budgeting with indication the individual items that affect the final price of the contract.
