A wood chipper with tractor connection
Šaroun, Martin ; Škopán, Miroslav (referee) ; Malášek, Jiří (advisor)
The aim of this bachelor's thesis is to design a woodchipper with a connection behind a tractor. From the beginning, we focus on different types of woodchippers and thein parameters. Below are some calculations of the parts that make up a chipper. The work includes 3Dmodels with drawings made in Autodesk Inventor 2020.
Design of a stubble disc cultivators for aggregation with a tractor 50k
Pech, Vladimír ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This thesis deals with the design of a stubble cultivator for a tractor. The aim of this thesis is to design a stubble cultivator that fulfill the conditions of the assignment. In this thesis is a search of similar machines available on the market. Followed by describes the methods of tillage which the proposed stubble disc cultivator is used. The next part of the thesis describes possibilities of stubble cultivator their advantages and disadvantages. The design part deals with the construction which is based on drawing documentation. In the next part of the thesis is a calculation which is focused on determination of the required tractor power that is needed for operation with the designed stubble disc cultivator.
Tracked vehicle for transport of the pallets
Blažek, Martin ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the design of a remotely controlled tracked vehicle for the transport of pallets on unstable ground. The aim of the work is to make a short research of similar tracked transport machines and to design concept including choice of vehicle drive, design of pallet lifting equipment and strength calculations of sub-parts.
Crane crab traverse mechanism load 25 t
Zicho, Jan ; Pokorný, Přemysl (referee) ; Škopán, Miroslav (advisor)
The bachelor's thesis deals with the construction concept of the crane crab travel mechanism for a bridge crane with a load capacity of 25 000 kg. The research section deals with construction solutions used on the travel mechanism of crane crab. The thesis contains a construction concept of individual components of the travel mechanism which include wheels, motor and transmission, brake, driveshafts, bearings, and frame. Subsequently, this thesis contains a calculation of these components and their check-up. The output of the thesis is a technical documentation containing the drawing of selected components and assembly drawing.
Stroke mechanism of bridge crane 16 t
Kolegar, Vojtěch ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with design of hoist mechanism of bridge crane with maximum load capacity 16 000 kg. First part consists of critical survey of existing designs made by several companies with subsequent choice of suitable conception. Main part consists of calculation of fundamental parameters of hoist mechanism that are important for definition and selection of further parts of mechanism like steel rope, pulleys and pulley block with hook. Other selected and checked parts of hoist mechanism are rope drum, electromotor, gearbox and brake. Last part of this bachelor thesis consists of selection of bearing, bearing housing, spring of output gearbox shaft, pin and welds. The output of this bachelor thesis are technical drawings of hoist mechanism and weldment of rope drum.
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.
Screenig shovel for construction and demolition waste
Běluša, Jiří ; Michele, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis contains design of a screening bucket used as an attachment for an excavator. Research section consists of construction and demolition waste sorting process, recycling options and design examples of screening buckets. Next part of the thesis includes own design of a screening bucket, calculations and finite element analysis using a computer program.
Design of a spraying unit for a mower with an electric drive
Frühbauer, Jiří ; Zápotočný, Václav (referee) ; Škopán, Miroslav (advisor)
The aim of this diploma thesis is to design a prototype spray unit. The design of the sprayer fluid circuit and construction is in accordance with the applicable legislative requirements for the given type of professional equipment. The work describes the theory and machines for spraying with the design and calculation of the sprayer fluid circuit. Furthermore, the design solution, kinematics design and inspection of the rotating frame of the device using the finite element method are described. Part of the work is also drawing documentation.
Safety valve for presses
Macků, Ondřej ; Vostřel, Josef (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the design of the safety pneumatic valve. This valve is a part of the two-handed control system device which is used with mechanical press. Operational calculation of important parts and strength control of the most stressed construction part is done in this paper. Further the calculation defining leaking of compressed air from one of the chamber of valve is presented. The result of this calculation is the time dependence of the chambre pressure. Partial drawing documentation which contains production drawings of the main parts of valve and the drawing of the assembly is a part of the appendix.
Design of automatic rack warehouse management
Trnovec, Šimon Peter ; Štoček, Jiří (referee) ; Škopán, Miroslav (advisor)
The subjec matter of this diploma thesis is designing a material flow logic of an automated storage and retrieval system to the producion area of a plant. The logic control is visualised by a flow chart and a matrix of experiments is compiled to evaluate the AS/RS functionality. Experiments are performed with a simulation model created in the Siemens Plant Simulation software
