Using tribodiagnostics in predictive maintenance in company practice
Trost, Daniel ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The thesis deals with the use of tribodiagnostics in predictive maintenance in corporate practice. It is generally dealt with maintenance, then tribodiagnostics in the company Škoda Auto a.s. Used offline and online diagnostic tools are described. Emphasis is placed on verifying the functionality of the newly purchased online filter unit. The experimental part is focused on detailed analysis of the above, including comparison of measurement results offline and online diagnostics. There is also an economic evaluation of savings obtained by operation the online filter unit. In conclusion, the tribodiagnostics recommendations are given for Škoda Auto a.s.

Production of anemostat
Bíba, David ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis handle design of part of anemostat in size of series 15000 pcs/year. Due to conus shape and dimensions of part was chosen out of quantity of manufacturing processes a technology of deep drawing without a thinnig of 1mm thick DC04 steel. The resulting solution is progressive tool which concatenate four operations of deep drawing process. The drawing tool make use of standardised components. The design contain progressive tool including drawing documentation. Hydraulic press CTH 400 with nominal force 4000 kN is used for mentioned procedure.

Engineering design of the hydraulic press for bearings for bikes
Vichr, Tomáš ; Brandejs, Jan (referee) ; Klapka, Milan (advisor)
This bachelor thesis concerns design of a bearing replacement device in the motorcycles wheels. The aim was to develop an affordable and reliable home appliance. In general research are defined the imperfections of commonly available devices on the market. Based on that are designed three conceptual proposals as a solution of these problems. The most suitable one is chosen and the critical crucial points are verified as well as the production price.

Production of uncapping tray
Čudová, Monika ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the extract - tray made of stainless steel 17 240. Based on literary study of deep drawing together with calculations, was designed drawing in instrument with holder. The drawing instrument make use of standardised components and it is solving forms to make up stand fitting to hydraulic press CYS 320, with nominal tensile force 3200 kN. Drawing punch and drawing die are produced from high alloyed steel 19 573 heat-worked according to drawing documentation.

Production of the upper part of gasoline tank
Minář, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of the upper part of the gas tank. Taking into account the shape and dimensions, the solution was chosen the most advantageous drawing technology without a thinning of 1 mm thick DC04 steel. The solution took account of the requirements of the contracting authority and selected the production for one operation. However, the simulation proved inappropriateness of the solution, so the procedure was modified to two operation proces. At the first stroke, a larger part of the body will be created, and in the other, a calibration of the cut-out dimensions will occur. For the first operation, the design of the tool kit, including drawing documentation for the CTH 250 press, was elaborated.

Design of working part of the hydraulic circuit for hydraulic press
Pospíšil, Lukáš ; Šanca, Marek (referee) ; Škopán, Miroslav (advisor)
The master’s thesis is focused on the proposal of working part of the hydraulic circuit for the hydraulic press with a press force 400 kN. The thesis contains justifiable structural design of the linear hydraulic motor, which includes material choices, necessary calculations and simulations of material strength characteristics and the choice of the individual components. The thesis also includes a proposal of “heel valve” including the choice of individual components and basic function calculation of the hydraulic circuit of the hydraulic press.
