Virtual Prototype of Electrical Machines in ADAMS
Lysák, Jan ; Hadaš, Zdeněk (referee) ; Vetiška, Jan (advisor)
The following thesis deals with the methodology of mechatronic systems design using virtual prototypes. Virtual prototype contains a computer simulation model, whose behaviour represents a physical prototype system. This approach allows to obtain knowledge about the behavior of the developed product before it‘s manufacturing. This leads to shortening new product innovation cycle and lowering the cost of innovation. The first part contains a brief search study of electrical machinery and description of the virtual prototyping. Then the prototypes of electric drives are created, that can be implemented into the more complex machine systems. The work also includes the realization of co-simulation and control design for one of the drives.

Proposal and Design of Electromagnetic Shock Absorber
Sirota, Tomáš ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This paper deals with the problem of electromagnetic dampers and their design. Compares several different technical solutions. It prepared the basic structure of the shock and the initial draft of the parameters based on the need for usability in real off-road model and simulation of mechatronic systems in the program MATLAB / Simulink and subsequent modification and tuning of parameters specific technical solution chosen. Furthermore, the work deals with management options electromagnetic damper settings manually, or using a controller.

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.

Modeling of thin-walled frames mechatronic systems with fillet welds and their influence on the natural frequency
Appel, Martin ; Hadaš, Zdeněk (referee) ; Vosynek, Petr (advisor)
This bachelor thesis is focused on methods of reduction degrees of freedom and their application in mechatronical system. Next part is focused on fillet welds and their modelling in Ansys Workbench software. Individual possibilities of geometry of welds are analysed by modal, static and harmonic analysis. Aim of this thesis is comparison of results of analysis for different methods of geometry of welds. Then it compare results of modal analysis in Ansys Workbench and Adams software. Finally the work deals with possibilities of exporting from Ansys Workbench to Adams, Matlab and Excel software.

Structure modeling of mechatronic systems with spot welds and their influence on the eigen frequency
Gajdík, Michal ; Hadaš, Zdeněk (referee) ; Vosynek, Petr (advisor)
This bachelor thesis examines various types of spot welds in Ansys Workbench 13. In first chapter of this thesis are described theoretical foundations of simulation modeling. In following phase are analyzed each methods of simulation modeling. Practical part is about realizing different types of spot welds and examining their impact on clamped boards. Outputs of this thesis are modal abilities of each executed type of spot weld. On attached CD are program annex and project in Ansys Workbench 13. The goal is to analyze differently modeled spot welds, displaying primal deflections and comparison of modal abilities.

Re-design of steering servo-actuators for Car4 experimental robot
Vespalec, Tomáš ; Hadaš, Zdeněk (referee) ; Vejlupek, Josef (advisor)
This thesis deals with the development and design of the wheels mechanism in an experimental vehicle Car4. During this work, we introduce the vehicle axle load calculation, with components and systems, allowing linear and rotational motion, and different design proposals for the application of these systems in the vehicle. The result of this work will be a new mechanism for the wheels of the experimental vehicle Car4.

Analyses of Mechanical Tasks in SolidWorks Motion
Cikánek, Pavel ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
The main goal of this thesis is to create and to simulation the samples from area of the kinetics and the dynamics in CAD system in order to be used as the teaching models. The examples will be created as simply and easily rebuilt 3D models in CAD program SolidWorks and they will be analysed in the Motion modul. The main task is to compare the results from SolidWorks Motion program with the current solution, eventually with the other CAD system. At the end the advantages and the disadvantages of SolidWorks Motion program will be evaluated.
