Design of Car Initiator
Suchý, Jan ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The bachelor thesis is focused on proposal solution of automotive initiator construction and design. The proposal is being carried out with regard to the need to ensure the maximum functionality of the whole element. As for the choice of materials and used technology the costs and procedures commonly used today are not being taken into account. The main objective is to eliminate the shortcomings of current automotive initiators and the proposal of technological procedures in the production of a new component.

Homologation testing of electric bicycle fork
Bejdák, Jan ; Suchý, Jan (referee) ; Hurník, Jakub (advisor)
Currently, the popularity and demand for e-bikes is growing rapidly. E-bikes entering the European market must meet a series of safety requirements included in the type-approval. This work deals with the prediction of the result of mechanical static testing of an e-bike fork according to the valid European standard. The prediction is formulated on the basis of FEM simulations of the mentioned tests and optical experimental measurements performed for the purpose of validating the simulations. The results of both approaches are compared and critically evaluated. The sample of the tested fork met the requirements set by the standard. Requirements for the prediction of a non-particulate test are set.

Design of the triaxial vibration positioner for removing residual powder from the metal prints
Šváb, Čeněk ; Šperka, Petr (referee) ; Suchý, Jan (advisor)
This bachelor's thesis is focused on the construction of a two-axis positioner, designed for removing dust out of parts created by a 3D printer SLM 280HL. The aim of this work is to design the construction of a two-axis positioner with an integrated vibration drive. The first part deals with the description of the types of manipulators and vibration motors. Based on the obtained information, the construction issues are outlined and various design tips are proposed to address it. The most suitable design is then selected and elaborated in detail. The output is a functional design solution of a two-axis positioner with an implemented vibration motor and the ability to run in a dusty environment.

Commercial vehicles powertrains design
Krupa, Lukáš ; Suchý, Jan (referee) ; Fojtášek, Jan (advisor)
In this work there are described parts of powertrain of currently used commercial vehicles and their configurations depending on the conception and purpose of vehicle. Individual parts of powertrain are described in terms of both design solutions and operating principle. The work is of the retrieval of character and serves as a source of information about the issue. It can be used for example as a teaching tool for getting deeper knowledge about the topic of powertrains of commercial vehicles.

Systems for performance flow distribution in vehicles powertrain
Novotný, Petr ; Suchý, Jan (referee) ; Fojtášek, Jan (advisor)
The bachelor thesis tries to provide compact knowledge about differential systems. In the first part of the thesis you can find information about basic function and differentials are divided into several groups. Second part describes elementary kinematic and torque quantities which have significant influence on the character of differential. Last part of my thesis is concerned with groups of differentials mentioned in the first chapter. Also in the last part there is place devoted intelligent differentials which are nowadays on a market.

Service Development
Suchý, Jan ; Maňas, Kristian (referee) ; Kubíková, Zuzana (advisor)
The bachelor thesis describes the development of digital products / services within a long-term collaborative project, reflecting current processes and tools used in creating visual outputs (graphic and text editors, cloud services for file sharing, platforms for organising collaboration). Existing software usually slowly reflects technological developments, causes unnecessary errors in communication between creators and generates unnecessary tasks. Most work takes place offline, products and services are not compatible. Emerging web applications / service co.llaborate.online have ambitions to solve these problems and automate part of workflows

Processing of high-strength aluminum alloy AlSi9Cu3 using selective laser melting technology
Suchý, Jan ; Hutař, Pavel (referee) ; Paloušek, David (advisor)
Method selective laser melting can produce metal parts by using 3D printing. This diploma thesis deals with the influence of process parameters on the workability of AlSi9Cu3 high-strength aluminum alloy using selective laser melting. The theoretical part deals with relations between process parameters and identifies phenomena occurring during the processing of metals by this technology. It also deals with conventionally manufactured aluminum alloy AlSi9Cu3. In the work, material research is performed from single tracks tests, porosity tests with different process parameters and mechanical testing. Here are showing the trends of porosity change at scanning speed, laser power, individual laser stop distance, bulk energy, and powder quality. The workability of the material can be judged by the degree of relative density achieved. Simultaneously the values of the achieved mechanical properties of the selected process parameters are presented. The data obtained are analyzed and compared with literature.

Measurement of the suspension flexibility
Suchý, Jan ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
The thesis is focused on the method of determining the position of the wheel using photogrammetric equipment Tritop. Verification of the method is performed by measuring of the Formula Student Dragon II. Measured data are processed by algorithm for calculating compiled in Matlab software. The final section describes a concept the measurement of the suspension flexibility on the UADI device.

Replica of a historical machine gun mount
Doležal, Jakub ; Suchý, Jan (referee) ; Maňas, Pavel (advisor)
This bachelor's thesis deals with the analysis and construction of the Královopolská gun mount replica, which were equipped in selected objects of Czechoslovak border fortifications before the World War II. This work is devoted to the analysis of the original documents for the gun mount, CAD model creation, 3D scanning and modification of scanned polygonal mesh of the heavy machine gun vz.24, which was selected as an example of machine guns mounted in the Královopolská gun mount. This is followed by a virtual compatibility check of the gun mount model with the machine gun model. The production model creation is introduced in next part, using technology with the lowest possible production costs. Complete drawing documentation for the replica production is also part of this bachelor thesis.
