Design Optimization of Contact Force Vector Sensor
Vála, Pavel ; Vlach, Radek (referee) ; Krejčí, Petr (advisor)
The aim of this work is an optimalization of vector contact force sensor properties which prototype is at the moment designed. The principle of sensor is based on transformation active part of sensor using three tensiometers and following value indentification of loading force vector using neuron network. Sensor has a bad sensitivity when axis force load or near to axis of sensor. To solve this problem ''MKP'' model of sensor was used on which suitable optimalization method was applicated. From the result of optimalization modificated sensor will be proposed and will be made a utility verification using neuron network.

Topological optimization in technical practice
Mazoch, Jan ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
Master’s thesis deals with an issue of 3D printing and of using a topological optimization for editing a shape of a 3D printed product. First part of this thesis provides a general description of a subtractive manufacturing technology, specifically its use in CNC milling machines, and of an additive manufacturing technology which is used in 3D printing. Second part of this thesis describes the topological optimization per se and specific methods which are used in the topological optimization. In the third and the fourth part of this thesis, topological optimization modules of software Ansys and SolidWorks are described. In the fifth part of this thesis, the topological optimization capabilities for 3D printed product on a specific embodiments of a design lightning and a cross-beam are demonstrated.

Topology optimization of frame
Vagner, Radim ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor thesis deals with the problem of topological optimization in the design of machine components and structures. The first part contains a condensed view of the basic methods of topological optimization. The second part contains the actual solution to the topological optimization of a frame, represented by a simpler part. It concludes with an evaluation and comparison of both the part itself and design approaches to the topological optimization problem.

Review of methods for the post-processing of topological optimization results
Kopačka, Ján ; Ježek, Ondřej ; Gabriel, Dušan ; Šotola, Martin ; Rybanský, David ; Maršálek, Pavel ; Halama, R. ; Tejc, J. ; Pašek, M. ; Kovář, L.
The research report is an output of the sub-project TN1000024/08: Automation and production system optimization in cooperation with MECAS ESI Ltd on the development of methods for post-processing of topological optimization (TO) results. In this report a detailed survey of these methods is introduced as necessary tool for seamless integration of the results TO with subsequent numerical simulations and additive manufacturing. The selected method for post-processing based on a level-set approach using radial basis functions has been implemented and successfully tested on a well-known 2D Messerschmitt-Bölkow-Blohm (MBB) beam test problem.

Design and production of selected 3D printed metallic parts
Masson, Quentin ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Thales LAS France currently has parts of their system that are manufactured by forging or casting. Nowadays the tools and equipment for those processes are getting worn, the sub-contracting company in charge of some of casted parts can’t guarantee the quality of those parts anymore. Moreover, Thales recently has set up a plant specialized in metallic additive manufacturing and the policy of production is to encourage the production in that subsidiary. In order to adress those issues, Thales LAS France managed to prepare his design office for designing parts that will be 3D printed. My function is to establish a methodology for the mechanical design of parts that will be manufactured in additive manufacturing. Once the researches about the process and the different technologies will be done, I will establish steps that must be achieve for the mechanical design of a piece or a system. The methodology will take into account the physical properties that can be guaranteed by the process and their flaws such as the porosity for instance, the constraint linked to the technology and if possible apply to the part a topological optimization.

Design and optimization of hydrostatic pocket space
Minář, Petr ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
This diploma thesis deals with an optimization of hydrostatic slide of the large-portal gantry machine FRU (TOS Kuřim). First part of the thesis concerns with an analysis of the current practice in hydrostatic guides in the field of heavy gantry machines, an usage of alternative materials for a construction of carrying parts of machines, and possibilities of current simulation methods. Aim of the second part of this thesis is a brief clarification of the principle of mathematical optimization, and creation of general methodology of construction optimization by means of system analysis. Optimization calculations were processed by ANSYS Workbench 11.0. There is achieved adjusted and optimized design of the hydrostatic slide as the result of the thesis. Moreover, the comparison of key deformations was added. Created methodology is applicable in both an area of construction of gantry machines, and a wide spectrum of construction fields.
