The two-coordinate numerical controlled table for milling center with hydraulic clamp
Nešpor, Vít ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
This thesis deals with theoretical design of NC rotary tilting table for Kovosvit MAS milling machine MCV 754 - QUICK. In the beginning of this paper is made a research with focus to rotary tilting tables, paletizing technologies and rotary suppliers of energy. The main part concerns with loading analysis of rotary tilting table, proposal of motion drives, bearings and the frame of desired machine. For motion drive of each axis is chosen torque motor. Constructional solution of pressed air supply to the middle boring of face plate is realized by a rotary union. The next point of solution is arrangement of moving supply electrical and pneumatic energy to the frame of tilting axis. The last part is concerned to proposal of realizing of changing tchnological pallets by the Zero-point systems. In the end the economical analysis is made.

Comprehensive System for Road Accident Analysis - Collision Between Vehicle and Motorcycle
Slepánek, Petr ; Kolíbal, Zdeněk (referee) ; Drahotský, Ivo (referee) ; Kropáč, František (referee) ; Bradáč, Albert (advisor)
This dissertation describes the issue of a complex system for analyzing the collision of a motorcycle with another vehicle and suggests a suitable methodology for solving this type of traffic accident. It summarizes the current knowledge in the field of motorcycle accidents withother vehicles, including their statistics and categorization. The author statistically evaluates accidents by their causes and proposes a methodology for solving individual types of motorcycle collisions with vehicles. To supplement and refine the input data for the analysis of road accidents involving motorcycles, a set of author’s own measurements made on different types of motorcycles is included. The thesis contains measurements of their acceleration, deceleration and avoidance maneuvers. Other actual contributions of the thesis are represented also by flowcharts, offering a comprehensive approach to solving individual types of colissions of motorcycles with other vehicles.

Description of different sorts of HARMONIC-DRIVE gear box
Brus, Jan ; Pavlík, Jan (referee) ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
The Bachelor’s thesis contains a technical search describing different sorts of harmonic drive gear-boxes. The search is engaged in the description of characteristics and possibilities of the application of particular sorts of harmonic drive gear-boxes, including operating characteristics (graphs), analysis of individual parts and the principle of operation. Further a comparison with other types of commonly used gear-boxes (cycloidal, classical gear-boxes) is presented. In the end the advantages and disadvantages focused on the usage and characteristics are summarized.

Orientation mechanism of industrial robots
Kočiš, Petr ; Kolíbal, Zdeněk (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with an orientation mechanism of industrial robots for mounting of pivots and screws into the mounting holes. In the first phase there is a research of inventions mainly realized in the United States Patent and Trademark Office database. Subsequently the conditions of the assembly are solved. On the base of the conditions the functional requirements are described. The diploma thesis includes seven conceptual variants, which are proposed as a 3D design. Using the basical multi-criteria method the best conceptual variant is specified. That is specified due to the accepted criterias. In the next part of the diploma thesis there is a calculation, that comprises this technically and economically most promising conceptual variant. The calculation consists of a statics, a kinematics and a dynamics of the propel, a stenght control of the mechanism and kinematics analysis of the whole mechanism. Results of the calculation are used by the detailed design of orientation mechanism, that also comprises technological production theory and a correct assembly. Economical analysis, which comprises cost of produce of this newly developed automation equipment, is worked up in the conclusion of the diploma thesis. The diploma thesis also comprises drawings. The variant solves a new conception, which can be patented as an utility model.

Complex System of Traffic Accident Analysis - - Collision of Vehicles on the Crossroad
Semela, Marek ; Kolíbal, Zdeněk (referee) ; Prochazka, Eduard (referee) ; Bradáč, Albert (advisor)
Thesis deals with problems of forensic technical analysis of traffic accidents, concretely with creation of complex methodology for analysis of traffic accidents of vehicles on the crossroad. There are defined terms of "complex system and complex analysis of traffic accident", technically acceptable range of important input values, systematization of accidents on the crossroad with methodologies in the thesis. Thesis shows problematical expert procedures, suggests scheme of expert evidence and includes methodology of measurement of common movement of vehicles on the crossroad and recommendation for expert procedures.
