Simulation of Heat Transfer in Low-Voltage Switchboard MNS - Optimization of Heat Transfer into The Switchboard
Czudek, Aleš ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
The thesis includes diagnostics temperature field of industrial low voltage. Place of origin, flow and heat transfer are important aspects in the design of the switchgear, especially in terms of proper equipment layout. The correctness of the design of the switchgear is verified by measuring the practical temperature field during testing or in work mode. To determine the temperature profile, it is necessary to measure the temperature at various points of the switchgear, either contact or contactless method. Measurements are performed on standardized low voltage switchboards, which are located power elements. The goal is to replace costly and time-consuming field testing switchgear efficient simulation of the temperature field mathematical model developed switchboards.

Analysis of the influence of the gas flow in the placement of the sample in the chamber of the environmental scanning electron microscope
Bednář, Eduard ; Bílek, Michal (referee) ; Maxa, Jiří (advisor)
This thesis deals with the simulation of fluid dynamics in environmental scanning electron microscope and evaluate solvers setup, the degree of discretization, choice of turbulent model and proposal optimal design of environmental scanning electron microscope. The theoretical part describes the issue of environmental scanning electron microscopy, software SolidWorks and ANSYS Fluent, basic equations describing fluid status, fluid turbulence, the mean free path of molecules and electron scattering. The practical part of the thesis is to create the model of environmental scanning electron microscope AQUASEM II in CAD system SolidWorks and simulation of fluid flow in the sample chamber before aperture PLA1 by ANSYS Fluent. A series of simulations provided the perfect setting solver. These knowledge are used in the second stage of the practical part, where is proposed optimal shape of the table sample and the input aperture PLA1.

Design of an extensible platform for mobile robot
Šumšal, Zdeněk ; Krejčí, Petr (referee) ; Krejsa, Jiří (advisor)
This thesis is about the design of the telescopic platform. which should be fasten on robot called Breach. Purpose of this platform is to carry another equipment like sensors, cameras or manipulator. The platform has to provide chiefly the high demands on load capacity. Another part of the thesis is design of mechanism placed on this telescopic platform, or just on the robot Breach. This mechanism has to load up small subject on the top part of the platform and then unload it on chosen place. Only thing defined for this subjekt is maximal weight of 2 kilograms, but other parameters aren´t specified. Construction is therefore focused on maximal versatility of this mechanism.

Modelling of Dynamic Tasks in SolidWorks Motion
Podzemný, Zdeněk ; Donát, Martin (referee) ; Hadaš, Zdeněk (advisor)
Aim of this thesis is creation 3D models of dynamic tasks (which were solved in subject Dynamics) in SolidWorks software and simulation in Motion module, which is part of SolidWorks Professional. Models can be used as a tutorial or educational help in Dynamics. The thesis is begun by description of Motion module and it's functions, then analytical methods of solving dynamic tasks are examined and after that is made a description of simulation in particular tasks together with simulation results. Almost every task is analytically solved and results are compared with simulation. In the conclusion of this thesis are discussed all results and simulations.

Modeling of linear drive for control design purposes
Drábek, Jakub ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
Thesis deals with the design of control of linear drive by taking advantage of connection between tools provided by NI LabView graphical programming environment and SolidWorks 3D CAD system. This work describes the various resources the CAD systems provide for virtual modeling of mechatronic systems and their simulation. Control is designed using simulation tools by utilizing link between NI LabView and SolidWorks, while the invented control mechanism is finally tested on real system.

Simulation of Impact The Heated Bed on Printet Model in 3D Printer
Sodomka, Petr ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This diploma thesis solves the 3D printing problematics for non-commercial printers. Firstly possibilities of its using, heat diffusion and printing materials are described. Next part of thesis is focused on heating pads and printing nozzles for which 3D models in SolidWorks software are created. The temperature analyzes are tested with these models and then comparing of results is done. Working models for SolidWorks Plastics and SolidWorks Simulation software is created in following part. Thanks to this software tools printing model is simulated and deformation creating in printing process is observed. The most suitable solutions are chosen from gained solutions.
