Inovace PPK GNSS senzoru Titan v posuzování zemětřesné kinematiky
Šugar, Danijel ; Ukas, Mladen
Within the sotware package Trimble Business Center ver. 5.90 (May 2023) was released a novel PPK GNSS processor named Titan. It utilizes all available GNSS constellations bringing improvement over the previous processor. CROPOS as the national permanent GNSS network of Croatia was modernized in summer of 2019 and since than it provides observations of all available GNSS constellations, namely, the GPS, GLONASS, Galielo and BeiDou. On March 22nd 2020, the wider area of Zagreb was hit by the M5.4 earthquake. The closest GNSS station to the epicenter (approx. 9 km) was the station ZAGR in Zagreb downtown and as such it was subject to earthquake shaking. Although the kinematic effects of that earthquake have already been assessed and examined, with this approach and novel PPK GNSS processor we are attempting to provide new insights into the earthquake kinematics involving observations from several CROPOS's GNSS stations in wider area around Zagreb.

Návrh vozidla Baja SAE
Hajdušek, Zdeněk ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This master’s thesis describes the design of the Baja SAE vehicle according to the applicable rules. In the beginning is the work focused on search competing vehicles and subsequently on design the first Baja SAE vehicle in the Czech republic. This thesis is systematically divided into chapters according process to the vehicle design. The main part of a master's thesis is design of axle kinematics in software Adams and frame design. The model was designed in Catia V5. The frame was analysed of torsional stiffness and stress in software ANSYS.

Testing platform with 3 dof
Spáčil, Tomáš ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
This thesis deals with development and construction of parallel manipulator with three degrees of freedom whose assumption of usage is testing tanks for NH3. In this work we are going to investigate the design of the mechanism in Matlab Simulink. Design of the electronic is introduced and also the control program is developed. The result of the work will be a prototype of manipulator.

Analysis the safety mechanism of the trailers
Pantůček, Michal ; Kubín, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis is engaged in the analysis of a safety mechanism, which is a part of a truck trailer. This mechanism provides a safe and firm connection of a container to the trailer. Primarily abroll containers according to German standard DIN 30 722 are being transported. The introductory part of the thesis deals with the current traffic condition and the accident rate in the Czech Republic. Legislative requirements for safety elements of trailer technology for road transportation are further defined. They are followed by a recherche of industrial solutions for securing mechanisms. Consequently calculations to obtain necessary securing force were performed. An analysis of the mechanism kinematics was carried out then. A structural check of selected mechanism elements was carried out following the kinematics check. Further, an optimalization of a transom design was carried out followed by another structural check. The structural checks were carried out using both the analytical method and the finite element method. In conclusion design documentation was elaborated. This diploma thesis was elaborated in cooperation with the SVAN Chrudim s.r.o.

Physics Simulator for SandBox Type Games
Kotulič, Patrik ; Peringer, Petr (referee) ; Hrubý, Martin (advisor)
This thesis focuses on the creation of a physics simulator of rigid body mechanics. The reader is familiarized with the principles used in current simulators of rigid body mechanics. The thesis then deals with numerical integration of the equations of motion, collision detection and collision resolution. The simulator is presented on a series of experiments. The resulting application can be used as a video game or as a tool for experimentation.

The MEMS sensors usability for position detection
Bobalík, Lukáš ; Sedláček, Jiří (referee) ; Žák, Jaromír (advisor)
Within this Master’s thesis, design and construction of a strapdown inertial navigation system based on MEMS sensors is described. The thesis includes theoretic analysis of physics behind determining the position of an object based on the object’s aceleration and changes in the object’s orientation in space. Included is also an overview of mathematical methods related to the position calculation.

Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.
