Stroke mechanism of bridge crane
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.

Influence of physical parameters and age of power lines on PLC/BPL performance and reliability
Benešl, Lukáš ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
BPL technology is quite widespread nowadays and the public is also somewhat aware of it. This technology can be used as a means of communication without the need to install additional media and thus use the existing infrastructure. In an effort to use the full potential of the technology, BPL communication began to be used to monitor the current state of cables in distribution networks online. Where the technology is already fully implemented, the distributor can use the data to evaluate the current situation. In this way, BPL technology can be used as a diagnostic tool to test the quality of a cable connection on which not only time but also humidity and other external influences could have a significant effect.

Stroke mechanism of bridge crane
Ujčík, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis deals with the design of a stroke mechanism of the bridge crane with capacity of load 12 000 kg, which will have served as a plant crane with regular use. The first part of this thesis is devoted to the critical research of similar existing solutions, on the bases of which a suitable order of the arrangement is chosen. The other part of the thesis is devoted to the calculation of the main dimensions of the stroke, on the basis of which the individual components are selected, this are hoist elements of the rope system, such as roller, rope and rope drum, in which the fatigue calculation is performed. Another part of the thesis tackles design and parts calculation of the lifting mechanism, such as electric motor, clutch, brake and gearbox. The final part of the thesis is devoted to the calculation and control of the drum flail, bearing and tension calculation of the parallel key. Constituent part of this thesis is also drawings´ documentation, which enclosed drawing of the lifting mechanism assembly and the welding subassembly as well.

Stroke mechanism of bridge crane
Tomeš, Jakub ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the design of bridge crane lifting gear for a load not exceeding 10,000 kg. The work includes the design of the basic parts of the lifting gear, such as rope diameter, rope drum and rollers. There is also included the choice of standardized parts such as electric motor, crane gearbox, flexible clutch or drum brake. The last chapter describe the strength calculation of the rope drum and the bearing life calculation together with the design of welds and tight pen. The output of the bachelor thesis is the drawings of the cable drum weld and the mechanism of the lifting mechanism.

Study of torque vectoring clutch design
Cupák, Václav ; Porteš, Petr (referee) ; Fojtášek, Jan (advisor)
This work deals with the design of right and left torque vectoring control used in heavy commercial vehicle powertrains. The beginning of the work is focused on the description of the active differential system and on the clutches used in the automotive industry. Then the basic parameters of the experimental vehicle are defined and the choice of the clutch conception is made. Subsequently, calculations of geometric parameters of clutches and verification of their heat capacity is made. Conceptual design of the control mechanism is discussed in the last chapter. The aim of the work is the draft of the possible type of control mechanism for the given system with the possibility to use the information obtained for the further development of this system.

Design of magnetorheological clutch.
Nováček, Vladislav ; Dočkal, Aleš (referee) ; Roupec, Jakub (advisor)
This thesis deals with the design of the magnetorheological (MR) clutch. The extensive literature research with particular conclusions to each design variant of MR clutches or brakes has been done in the first part of the thesis. The second part of the thesis describes the design of the actual MR clutch based on the results of the analytical calculation of the magnetic circuit. Finally, the experiments verifying the function of the key segments of the clutch, and the whole clutch are summarized in the third part of the thesis.
