Formability of Thin Steel Sheets Coated with Anodized Aluminum
Hušek, Martin ; Suchánek, Jan (referee) ; Spišák,, Emil (referee) ; Dvořák, Milan (advisor)
Thesis deals with the design of the technological process of anodic oxidation (creating elox coating) on aluminium film in the system steel-aluminium-elox, with the findings of characteristics of this system, comparing with the contemporary knowledge and practical utilization of this system in practice. My thesis in the teoretical part describes creating of anodic oxidation (elox coating) and the process of bending and stretching the sheet. Theoretical aspects of interaction among elox finish, process of bendings and process of stretching are implemented in the experimental part and they are supported by identified knowledge and results. The practical part is focused on improving adhesion, designing and constructing a multifunctional bending product for testing resistance of the finish applied on a tested product. Under the terms of determination distributing deformation and tension in bended coated plate, this plate is tested by statistic analysis with the help of the Finit Element Method (FEM) in the programme ANSYS. The experimental part compares discovered results of each experiment in the system steel – aluminium – elox with the results of aluminium plates with elox finish, stainless plates and steel plates with aluzinc.

Production of form-parts by cutting
Tomášková, Veronika ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in a master's degree programme Manufacturing Technology and Management in Industry proposes a technology for cutting form parts. The part is made of steel EN S235JRG1 (ČSN 41 1373) with 3 mm thickness. Based on literature review with a respect to yearly volume of production (100 000 pcs/year) and surface quality has been designed new technology of fineblanking for manufacturing of the part. For the technology of fineblanking have been made technological analysis and the tool has been design regarding to the chosen fineblanking press Feintool X-TRA 320. The conclusion of the thesis deals with technical-economical evaluation of manufacturing process and also has been compared the price of the part using unconventional production technology.

London Eye
Hušek, Martin ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Performance of static analysis of the London Eye structure is the subject of this diploma thesis. First chapters of the thesis analyses overview of realized structures of the Ferris wheel. The main part of the thesis analyses the London Eye structure itself. Specifically are described response analyses, sensitivity analyses, analyses of ultimate limit state and serviceability, stress analyses, analyses of fatigue stress and lifetime analyses. The thesis describes among static analysis also a design of dynamic vibration absorbers. The results of each analysis are evaluated in the final chapters.

The Production Technology of unrotary part with flange
Přikryl, Zdeněk ; Hušek, Martin (referee) ; Císařová, Michaela (advisor)
Study describes application of forming technology for the production of unrotary parts with flange. The Study considers preliminary technology of forming processes in general. Further includes problems about drawing of unrotary parts with flange from singular to complex shaped. The next part of study includes evaluation of methods of the production belt gear shelter considering product criterias for series production and final accuracy and quality. Following part includes suggestion of the production technology of belt gear shelter using sheet metal forming. In the next parts of the study attends to accurate technological process elaboration of the components, to technological calculations and to project tool configuration. In conclusion the study includes technoeconomic evaluation of propřed technology production.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.

Manufacturing of Shaped Holes into Stamped Metal Sheet
Bartusek, Břetislav ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The aim of bachelor thesis is a proposal of a new technology for manu-facturing of shaped holes into stamped metal sheets. The sheets are made of stainless steel DIN 1.4301 of thickness 0.8 mm. Square holes will be punched into a half-finished metal sheet with pre-pressed lengthwise stamps where elastic-plastic deformations occur. On the basis of study of the sheet metal forming technology, technological calculations and the machine adaptation, a new technology is proposed. The new technology is unassuming both with respect to machinery and tool equipment in a mechanical engineering factory. Also it enables solutions of dimensionally variable die stampings with stamps in higher quality for minimum costs. As the forming machine a punching press, model LDR 25-A, was chosen.
