Design and implementation of tasks in the physical practice of mechanics and thermodynamics
KADLECOVÁ, Lenka
This thesis was created to design instruction papers for the physical experiments, which will be used in the Physical practice of mechanics and thermodynamics in the new premises of the Faculty of Science of the University of the South Bohemia. The work not only documents the theoretical background and approach to measurement, but also describes how these individual experiment sets were prepared and what the problems (and solutions) for each task were.

Aplikace mechatroniky v sedacím nábytku
Maňák, Hynek
The theme of the dissertaion is appliaction of mechatronics in seating furniture. The work defines the principles of mechatronics and presents samples of the existing applications of mechatronics in interior furnishing elements. The work describes the current status of the positioning of seating furniture and systematically devides particular positioning elements according to construction principles and function in term of changes in the ergonomic parameters of positioning furniture. In this description are captured current trends of progress in positioning of seating furniture with mechanical and electrical drive. The work defines the basic functional parts of the positioning mechanisms: guiding system, electric motors, control system, safety elements. The work specifies the logical elements that elevate electromechanical applications from mechatronic application. The aim of the work is the formulation of potential areas of application of Mechatronics in the sitting furniture. The work contains a theoretical vision and specific suggestions for application of mechatronics in the sitting furniture, complemented by proposals without the application of mechatronics.

Robot for MiniSumo
Marvan, Aleš ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This thesis deals with the subject of a mobile robot design for an international competition Minisumo. The work includes both a theoretical presentation of the robot design as well as the documentation of its realization. The development process starts with a creation of a theoretical basis, which is functioning as a source of information for the consecutive design of the mechanics, electronics and final production of the robot. The work also includes the development of control software necessary for the correct operation of the robot.

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.

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.
