Problems of critical wall narrowing in high pressure hydroforming
Drška, Jan ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
Bachelor's thesis deals with narrowing metal sheet wall by high-pressure-fluid forming technology on a practical example. This thesis is working on an issue from practice while using a non-standard problem solving method. Theoretical part outlines classical methods of hydroforming and the theories of sheet metal forming. Practical part consists of proposed solution and an elaborated simulation. Subsequently is described the ideal machine for hydroforming and technological procedure. Last part is devoted to technical and economical evaluation.

The use of fluid medium in forming technologies
Tůma, Martin ; Dvořák, Milan (referee) ; Peterková, Eva (advisor)
The aim of this work is recognition manufactoring methods making use liquid like forming media and estimation measurment their usage in present. Making summary of all methods, which make use liquid for manufacturing components. Further are here introduced examples of parts, which are used in practice, method used at their manufacturing and comparing advantages and hadicap in comparasion with conventional methods.

Hydroforming machine for non-ferrous material tubes
Ocelík, Jakub ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
Master`s thesis deals with unusual high-pressure-fluid forming technology – hydroforming. There are discussed factors, which are affecting forming process, and there are made conclusion of it for machine design process. There is also made an evaluation of tube hydroforming technology in nowadays. The objective of thesis is to design new forming machine for tube hydroforming and for use in bicycle frames design. The machine is to be determined for manufacturing series up to 1000 pieces. Based on calculations and discussion of hydroforming technology, the best design solution is chosen. Machine is designed as modular conception with pressure multiplication of forming fluid right in die cavity. There is no need to use high pressure pump for forming fluid, used in common machines for tube hydroforming. This leads to cost reduction and so the objective of thesis is accomplished.
