Analyses of Mechanical Tasks in ADAMS
Rybár, Šimon ; Švancara, Pavel (referee) ; Hadaš, Zdeněk (advisor)
The aim of this thesis was to create parametric models of technical systems in Adams software. The simulations were made to analyze the systems from kinematic and dynamic point of view. In some cases, the simulation results were compared with the results obtained by the analytic method. The thesis is divided into three chapters. The first defines the area and aims of the thesis. The second one defines multibody system and closely presents the software and its features. The third chapter contains five different examples which demonstrate the abilities of Adams. In the conclusion, own information, overall rating and educational recommendations are summarized.

Point particle kinematics and light propagation in de Sitter spacetime
Michalík, Tomáš ; Hinterleitner,, Franz (referee) ; Larsen, Klaus Bering (advisor)
V této práci se zabýváme de Sitterovou speciální relativiou, která se odehrává v de Sitterově časoprostoru namísto Minkowského časoprostoru. Začínáme studií grupy symetrie de Sitterova časoprostoru. Snažíme se použít tyto poznatky k rozvinutí kinematiky v de Sitterově časoprostoru. Dále přezkoumáváme spojení mezi elektrodynamikou na pevně zvoleném časoprostoru a elektrodynamikou v makroskopickém médiu v plochém časoprostoru. Toto aplikujeme na de Sitterův časoprostor a hledáme index lomu sdruženého média.

Simulation verify the dynamic behavior of the portal machine tool
Danda, Libor ; Holub, Michal (referee) ; Vetiška, Jan (advisor)
This bachelor thesis deals with summary of simulation software for the simulation of the dynamic behavior of machines, creating a simulation model of the machine in MSC.ADAMS and experimental measurement of cutting forces. It also deals with dynamics simulations axis motion and deformation analysis of selected components of the machine. Finally, they are designed to be structural adaptations in order to increase the dynamic stability of the machine.

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.

Analyses of Mechanical Tasks in Multi-body System
Ondrejka, Adam ; Lošák, Petr (referee) ; Hadaš, Zdeněk (advisor)
The aim of the bachelor thesis is to create simulation models according to mechanical tasks with the usage of CAD system Invetor and simulation tool SimMechanics, which will be further utilized in tuition. The accuracy of simulation would be evaluated in comparison with classic solutions. Finally, the pros and cons of SimMechanics would be summarized.

Simulation modelling of VNT mechanism kinematics
Zelda, Jan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with the modeling of kinematics VNT Turbocharger mechanism. In the first part, there is a general overview of supercharging combustion engines, search optimization methods and overview of the types of simulation models. Creating a simulation model and performing sensitivity analysis of each part follows. The final part of the thesis reflects the impact of clearance in the joins of the 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.

"Pat a Mat" by physics education at basic schools
MADĚRA, Martin
This diploma thesis deals with the processing of selected parts of the series "A je to" within the framework of an interactive teaching physics in elementary school. Thesis is divided into two parts. Theoretical, describing motivation and interactive teaching and part practical, in which they are processed, video materials and their theoretical analysis.
