Construction of a brake mechanism
Laštůvka, Martin ; Galas, Radovan (referee) ; Frýza, Josef (advisor)
The bachelor's thesis describes design of brake and arrestment mechanism for high pressure viscometer which is placed in the laboratory of the Institute of Machine and Industrial Design FME BUT. The Brake mechanism is able to brake torque of 50 Nm and the arrestment mechanism allows to stop the shaft at precisely defined angles. When designing the device is used current the state of knowledge.

Design of Tagnpps 97 m3 Wagon Braking System in SS Braking Mode
Trubač, Pavel ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
At first part of my work is described the brake for freight wagon, its princip and control. Next part is dedicated to describe to brake with block and brake with disc. Main object of my work is concrete propose of brake with blocks and reason, why is this brake use on most of wagons. Next I describe requests for brake accessories for freight wagons, mainly for operation in SS mode. At second part is proposal for brake for freight wagon type TAGNPPS for operating in SS mode. Scheme of mechanical and pneumatic part, CAD model of this brake system, voltage analyses by FEM method of choosing component – brake lever, created in SolidWorks 2011 mode. For compare of result by FEM method is used analytic count of this component.

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.

Auxiliary crab for overhead foundry crane
Adam, Petr ; Nezbeda, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis deals with issue design of crab trolley. Concretely is acted about auxiliary crab trolley with required capacity 65 000 kg. This crab is on overhead crane, which is situated at hall of foundry. In particular chapters is processed design of lifting mechanism and travelling mechanism, which is amended to strength control of frame. This whole leads to output solutions, which is drawing documentation.

Crane Stroke Mechanism
Vydra, Tomáš ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of crane stroke mechanism with lifting capacity of 12 500 kg. At the beginning is research of different design solutions, their comparison and finally selection of the most suitable conception. Before calculation part of each unit is short theoretical part, which brings basic information about issue, whose result in choice of product from catalogues. On the grounds of calculations, firstly hoist parts are chosen, such as rope, pulleys, rope drum and main units of crane mechanism – electric motor, gear box and brake with coupling. Final part deals with strength calculations of rope drum and drum shaft and design of his bearing housing. The practical part of the work are assembly drawings of crane stroke mechanism and rope drum weldment.

Stroke mechanism of bridge crane
Wiesenberg, Adam ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to develop a design of the lifting mechanism of a workshop bridge crane for a load capacity of 32,000 kg. The introductory part of the work is focused on a brief introduction to the issue, then there is a critical search of similar existing design solutions with related chapters dealing with the evaluation of concepts and selection of their own solutions and then follows the chapter Classification of crane and hoist. The second part of the work deals with the design and calculation of the main parameters of the lifting mechanism, including the choice of steel rope, rope hoists and calculation of the size of the rope drum. In other parts, the design and inspection of the rope drum, the selection of individual components of the lifting mechanism, such as the electric motor, gearbox, brake and clutches. The conclusion of the thesis contains the selection and method of bearing inspection, the design of the drum pin and the procedure of inspection of the tight spring joint. An integral part of the work is also the drawing documentation of the overall assembly of the lifting mechanism and the welding subassembly of the rope drum.

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.

Travel mechanism of a 60 t bridge crane with a rocker arm arrangement
Ptáčník, Michal ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor's thesis deals with the calculation and the design of a concrete running mechanism of the bridge crane, which moves inside the hall. The running mechanism is stored in a pendulum arrangement, and the lifting capacity of the crane is 60 tons. The research part deals with similar design solutions. Subsequently, the engine, gearbox and brakes are designed. Further, the calculation of the individual components of the running mechanism is carried out. The output of the whole work is the drawing documentation.

Analysis of Deceleration of Trams and Evaluation of its Impact on Standing Passengers
Skupová, Dagmar ; Fleissig,, Petr (referee) ; Vémola, Aleš (advisor)
The thesis is concerned with establishing the braking retardation and determining of it's influence for standing passengers. The thesis consists of three parts. The first part is theoretical and it is engaged in brake system of tramway. The second, experimentally part talks about practical establishing of braking retardation. And the third part of thesis is gived to discussion about established values of braking retardation. The aim of thesis is to find a value of braking retardation, when standing passengers don't fall down.
