Computational analysis of the steel-composite carrier of the machining center TM 2000
Zbožínek, Martin ; Obdržálek, Vít (referee) ; Vrbka, Jan (advisor)
The main objective of the work was to perform a computational analysis of the hybrid (steel-composite) carrier and compare the results with the original metal carrier. Static analysis, modal analysis and frequency response were solved. Computation was performed for three different relative positions of the carrier. Static stiffness, natural frequencies and dynamic compliance have been calculated. The results were verified by an experiment performed on a scaled-down model of the carrier. Modern software products, namely MSC Patran, MD Nastran, Matlab and ProENGINEER, were used for the calculation.

Stiffness estimation at the machining head and the strength analysis of the moving parts of the machining center MCV 1220.
Zbožínek, Martin ; Houfek, Martin (referee) ; Vrbka, Jan (advisor)
Main objective of the work was to estimate the possibilities and the limits of elementary stress and strain analysis of the construction. At the beginning it was necessary to simplify the problem to the 1-D bar problem. The calculation was performed for three typical loading cases, namely for the middle and the border position of the machining head. The contact forces and momentums and the displacements at the machining head have been calculated. The obtained results were then used for the stiffness evaluation of the construction at the machining head. The strength analysis of the moving parts of the machinig center has been done, too. Modern software products (Autodesk Inventor, ProENGINEER, ANSYS Workbench, Maple, Mathcad, etc.) were used for the calculation. The results were compared with The Finite Element Method results.

Industrial robot application in area machinning technology
Staněk, Michal ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This study analyzes the application of industrial robots and manipulators in the area of cutting. It portrays the evolution of this dynamic sector and its next possible advancement. It explains the basic categorization and division of industrial robots and manipulators (IRM). The author offers an overview of various applications of IRM, with typical examples of the correct use of different types in technological processes (turning, milling, grinding etc.) in order to effectively increase the production. The study also describes two robotized technological work sites that the author personally visited and documented in detail. This study is supposed to show the indisputable advantages of employing the automating elements into the mechanical engineering and to explain the basic concept of this industry.

Physical laboratory exercise preparing by using of educational system PASCO
DVOŘÁK, Jiří
The thesis is the preparation of practice of mechanics in physics lessons with the use of the educational system Pasco. At the beginning, there is a concise introduction with the educational systems; specifically the description of the Pasco system and description of individual sensors from basic set of sensors for physics, some of them are used in the implementation of laboratory tasks. This part also includes the Control software, Pasco DataStudio and the possibilities of further processing of the values using a spreadsheet. Next part of thesis deals with measurement methods, measurement errors and processing of measurement results in measurement protocol. The following section contains a design of four tasks of mechanics. Each task contains an introductory section, the design of laboratory workout, the process of construction measuring system, assignment, worksheet and procedure for resolving task. The first two tasks are focused on friction, the third task deals with the movement of the point on the circle and the last, the fourth role is focused on the motion of a body on an inclined plane. As part of the Annex are elaborated protocols of individual measurements and photographic documentation of the production process of measuring sets. In the conclusion there are evaluated results of individual measurements, which are based on practical verification in physics lessons at Secondary Technical School of Mechanical and Civil Engineering in Tabor.

Internet support for the physical practice in mechanics
KOVAŘÍK, Petr
The thesis consists of 80 pages, 6 pages of enclosure and a CD with web pages. Thesis focuses on computer support for the practice of physical mechanics. Its purpose is to document each measurement, which are implemented in practice, to propose some new measurement, to clarify the basic principles for data processing and writing protocols and materials found on the internet, which could help students both in preparation and during the actual measurements in practice.
