Design of universal hydraulic power unit
Holub, Vojtěch ; Pokorný, Jan (referee) ; Knoflíček, Radek (advisor)
The first part of this masters thesis deals with research of modulat type hydraulics power units from other significant world producers. Design part of thesis contains complete design of three product ranges of hydraulics power units. It also includes simulation by FEM method. Last part descibe safety of machine and brief economic evaluation of product.
Review and propose modifications to the cooling system of skid steer loaders B861, B961
Bečka, Pavel ; Pokorný, Jan (referee) ; Škopán, Miroslav (advisor)
The object of this diploma thesis is revision of coolant system skid steer loaders “BOBEK” B861, B961 and his eventually optimization for prevention of overheating hydraulic system and engine. The first part dedicate of general issues of coolant skid steer loaders. The second part is the calculation during heat stress hydraulic systems of loader and the third part include proposals for solutions problems of overheating hydraulic systems and combustion engine.
Design of micro drive for harvester
Jonák, Vojtěch ; Pokorný, Jan (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with design of hydrostatic drive for harvester. It contains calculations of parameters from current drive like speed, hydraulic losses and tractive effort. Because now these parameters are insufficient in next part of work is proposed few options how to achieve required parameters. In selected cases are made calculations and based on the results are recommended two options for realization.
A space heating system for a three-story row hose
Aulehla, Jiří ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This master`s thesis describes the design alterations that lead to a reduction in heat loss of the house, an extension of living space in the attic and the subsequent reconstruction of the heating system. The first is presentation of the house. After that, there is calculation heat loss of the house. The next step contains design of a reconstruction for every room and calculation modified heat loss. Another point this work is design the reconstruction of the heating system, extension heating system to the attic floor, calculation pressure losses and selection condensing gas boiler. After that is designed regulation with central control unit and electric thermostatic radiator valve. The last part of master`s thesis is focused on benefit assessment changes, budget and return of investment. The drawings are listed in the appendix.
Measurement of indoor environment by means of thermal manikin
Ševeček, Jan ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
This dissertation deals with the measurement of the internal environment through thermal manikin Newton, especially in terms of thermal comfort. Measurements were performed in a typical office environment and cabins of small transport aircraft. The course of events and the time constants for the measurement in the office was given by real flow in the office when the sequences of events were unfolded from the usual transactions carried out during the day. In contrast, the second measurement, which took place in the model of small transport aircraft, the course of events and time constants, was performed exactly according to predetermined plan. The other parts of the thesis describe how to calibrate the manikin and then generate a diagram comfort zones. Following are compared individual test cases and events using the diagram comfort zones. Finally, individual test cases and events are compared using the diagram comfort zones and medics according to ISO 14505-2.
Tool for robotic arm
Provazník, Tomáš ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The diploma thesis deals with the design of a fixture for a robotic arm used for manipulating noise and heat insulators employed in the automotive industry. The main objective is the design and the selection of components to meet the requirements imposed on the product. Further, design and control calculations of the components with operational information are reviewed. In the last chapter the thickness, the draft and the radius analysis of the molding with a description of the measurement is stated. Finally, the mechanical properties of the fixture frame were checked by the finite element method.
Adjustment of quick clamping equipment for application on screener crusher bucket
Hrňa, Lukáš ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the adjustment of quit camping equipment for application on screener crusher bucket Allu SC 3-20 in order to streamline both digging into the bucket, and the actual screening. Using simulation methods in the Adams programme, forces are detected for the digging with the original suspension. Imperfections are revealed for the current full suspension and suggestions made for the new proposedsuspension. The new shape quick release mechanism is designed in CATIA modeler and the I-Deas programme provides final strength control of parts for the proposed mechanism. Finally, both variants are coMPared in terms of digging, sifting the material complexity of the design and the necessary restrictive criteria.
The changeable strut devices for cranes in hall
Dvořáček, Jan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
This thesis was created for Bosch Rexroth in order to simplify the lifting work in the manufacturing hall. There was made the construction project of changeable strut devices for lifting loads. The project is comprised of two parts. The first deals with the analytical calculation and the second part consists of a numerical calculation using the finite element method.
Simulation of indoor environment in a small transport aircraft cabin
Knapčík, Lukáš ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
The diploma thesis is focused on ventilation and simulation of heating in small transport aircraft EV-55 cabin. First part explains an impact of thermal environment on human health and describes restrictions and recommendations forced on inner aircraft environment. In the first part are also clarified conditions of comfortable environment and thermal comfort evaluation for passengers via PMV and PPD index. The second part contains results from simulation of aircraft cabin environment. Inlet ventilation airflow and cabin heating is simulated via simulation mean Theseus-FE 3.0. The simulation results are evaluated for thermal comfort degree and optimal cabin insulation with optimal temperature and volume flow rate of inlet air is specified.
