Mathematical Model of motor vehicle driving gear
Marek, Petr ; Laurinec, Marián (referee) ; Porteš, Petr (advisor)
The subject of my master’s thesis is creating a mathematical model of motor vehicle driving gear using the software programs MATLAB / Simulink. The results are presented via graphs of the data gained from the simulation of a car driving on a determined track. The parameters used in the model come from a specific file and they can be changed anytime in order to correspond with the particular vehicle.

Atomistické simulace uspořádávání v niklových slitinách pod vlivem mechanického napětí
Buršík, Jiří
Systems containing up to six alloing elements typical of advanced Ni-based superalloys were modelled.their ordering was simulated at atomic level using a Monte Carlo approach with púeriodic boundary conditions and Kawasaki dynamics.molecular dynamics routines were embedded into standard kinetic Ising model to account for relaxing of local atomic positions.Straining computer experiments show that elastic parameters and bulk modulus undergo comparatively large changes at the beginning of ordering process.

Design of omni directional mobile robot (O3-X) control
Olša, Petr ; Ošmera, Pavel (referee) ; Matoušek, Radomil (advisor)
This thesis deals with the design of a three-wheeled omni-directional robot control. The model of control is designed for robot´s omni-directional platform driven by maxon motor with the intelligent positioning controller EPOS. The design of control contains: - installation of the coordinated systems and transformation from one of them into another - design of system´s kinematical model - creation of classes for control and communication with EPOS - creation of the simulative program - planning of the mobile robot´s path - verification that the system is working The solution was based on continuous accelerated motion and the maximal acceleration of wheels was concerned, so that the slip would be suppressed. The function of the model was partly verified.

Motion control during hanged object transportation
Richter, Jan ; Davidová, Olga (referee) ; Němec, Zdeněk (advisor)
The Diploma Thesis focuses on examination of most suitable optionsof movement regulation of pendent object from the perspective of various requirements on the course of the process as such. The environment of Matlab-Simulink was used for the analysis. The first part of the Thesis deals with the creation of the model of the whole system and creation of additional models of systems with similar, highly oscillating behaviour. The central part of the Thesis focuses on the design of suitable methods of movement regulation during translocation of the pendent object, which is tested on a simple model of travelling monkey. Four approaches to the problem solving were chosen: simple regulation by PID regulator, branched regulation, state regulation and predicative regulation. All solving options are being analysed and optimised and their results mutually compared according to requirements defined, such as: speed of the process, fluency of the movement, small pose overshoot or small angle of rope deflection.

Design of autonomous mobile robot.
Vodrážka, Jakub ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
The thesis deals with design of the device for testing the localization techniques for indoor navigation. Autonomous robot was designed as the most appropriate platform for testing. The thesis is divided into three parts. The first one describes various kinds of robots, their possible use and sensors, which could be of use for solving the problem. The second part deals with the design and construction of the robot. The robot is built on the chassis of the differential type with support spur. Two electric motors with a gearbox and output shaft speed sensor represent the drive unit. Coat of the robot was designed for good functionality and attractive overall look. The robot is also used for the presentation of robotics. Thesis provides complete design of chassis and body construction, along with control section and sensorics. The last part describes a statistical model of the robot movement, which was based on several performed experiments. The experiments were realized to find any possible deviations of sensor measurement comparing to the real situation.

FTC Control in connection with industrial robots
Mimochodek, Martin ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
This diploma thesis deals with a conception of force-torque control of industrial robot applied on a finishing technology of grinding. This work includes a classification of various force-torque sensors currently available on the market. The practical part of this thesis deals with a setting-up of communication and connection among the force-torque sensor SCHUNK FTC 050-80, PLC Beckhoff CX and industrial robot KUKA KR3. Practical part is further focused on a simple model of grinding, especially the grinding force control in relation to the robot movement.

Intanke and exhaust manifold for racing engine
Chuchma, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This Master’s thesis is focused on design and optimalization of intake and exhaust system of the C20XE engine. It is four-cylinder gasoline engine with stroke volume of two litres, which was produced by car company Opel. This engine is determined for Opel Astra F automobile, that is build for racing. For optimalization of dimension parameters there is used a Lotus Engine simulation software, which simulates one-dimension gas flowing in manifold. 3D CAD models are made in Pro ENGINNER software.

Con Rod design and optimization of racing engine
Ulman, Jaroslav ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This master thesis describes the design and optimization of connecting rod motor racing car. At the beginning of the whole work is a 3D-model of rods, from which then the whole work is based. Then it analyzes the current model of stress and on the basis of the results are made structural changes to the solution of rods. Newly adapted connecting rod is again analyzed using FEM and newly obtained results are compared with results of the original model of connecting rods. The conclusion deals with sensitivity analysis of selected parameters of rods and their potential effect on the resulting changes in strength connecting rod .Then is an assessment of all results.
