Assessment of the use of 3D printing technology in the automotive industry
Ondriska, Josef ; Libich, Jiří (referee) ; Binar, Tomáš (advisor)
This thesis deals with 3D printing technology and analysis of various polymeric additive manufacturing materials, with a focus on their application in the automotive industry. In the experimental part, three types of material are tested for mechanical properties, both without degradation and after degradation by a climate chamber. In the tensile strength test, the possibility of using acoustic emission as a diagnostic method was verified. From the results obtained, a specific part used in the automotive industry was designed. The work also includes the design of a stationary

Design of a slope generator for LIN bus transceiver with controlled slopes
Šlechta, Adam ; Háze, Jiří (referee) ; Kledrowetz, Vilém (advisor)
This thesis deals with the introduction of the basic types of communication protocols in the automotive industry. It then looks in detail at the LIN communication protocol, which is characterized by its high EMC requirements. The thesis thus contains a description of the principles of electromagnetic radiation. Then the thesis describes the design of LIN driver in the old I4Te technology and proposes its modification for the new technology. Furthermore, the thesis deals with the design of several blocks of the LIN driver. Namely, a DA converter and an input follower.

Study of implementation of SPC statistical method for control of technological operations
Ondruška, Jan ; Zeman, Karel (referee) ; Jurová, Marie (advisor)
The master’s thesis contains a procedure of implementation of statistical process control for a machining process in a chosen company. The method is based upon knowledge of this topic which are mentioned in the first part of the thesis. The output is a comparison of general process performance before and after implementation of the above-mentioned statistical method and evaluation of the influence of this new method at the process. The comparison is done using hypothesis testing of specific statistical variables and analysis of process performance and capability of both data sets. The acquired knowledge and experience will be used for implementation of statistical process control for other processes in the company’s production portfolio.

Mechanical properties of fiber reinforced composites for automotive applications
Bayer, Adam ; Žídek, Jan (referee) ; Jančář, Josef (advisor)
Bachelor’s thesis deals with studying mechanical features of fiber composites. As a matrix was chosen PMMA and as reinforcement was chosen glass fabric. Theoretical part sums up contemporary issues of polymer composites in automotive industry such as their production techniques and methods of impregnation. In experimental part were prepared samples by block polymerization of 30 % solution PMMA in monomer with initiator by 65° Celsius warmth oath, when was fabric directly unfolded in pre-polymer solution. On these samples were executed tensile tests by testing device Zwick and these samples were compared with results of theoreticaly calculated values.
