Dynamically balanced resonance adhesive tester
Jandásek, Martin ; Růžička, Bronislav (referee) ; Mazůrek, Ivan (advisor)
This diploma thesis is dedicated to the development of mobile resonance-adhesion tester TriTec. The aim of this thesis is to improve the parameters of the tester in comparison to the previous version of tester, especially to minimize the vibrations of the tester while running without load, and to the make long-distance transportation of tester easier. The first part of thesis was aimed on history of development of TriTec tester, causes of it´s problems and on analysis of vibration minimization possibilities. As a best solution is considered a rotational balance mechanism, which was designed in next part of thesis. After that a new front wheel drive and an user interface conception were designed. The modified tester reaches all the deserved parameters and is able to compete static resonance-adhesion testers by it´s lower price and high mobility.
Skip loader NKR130V
Derka, Lukáš ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master’s thesis deals with a strength analysis of the main frame and loading arms of a skip loader. For a calculation of load states is used a dynamic simulation and its results are used as a boundary conditions for the strength analysis using finite element method (FEM). The results of the analysis is evaluated and on theirs basis are designed a construction improvements. The part of the thesis is drawings documentation of the construction improvements.
The trailer for a chipper
Poul, Ondřej ; Robotka, Tomáš (referee) ; Kašpárek, Jaroslav (advisor)
The goal of this thesis is structural design of the trailer for a LASKI chippers and to create a construction drawings. Important part is information about legislation rules, which this trailer has to fulfill. The aim of this work is to do a dynamic simulation using multi-body system. Results of this simulation are used for a stress analysis witch using a fine element method.
Trailer frame VARIANT 200 for transport cabel spools
Blažek, Jaroslav ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a cable trailer VARIANT 200. For the calculation of load states was used a multi body system in program MSC.ADAMS. The results from these calculations were used as lifting conditions for strength control with finite element method (FEM). All acquired results were analysed and according to them changes were made to the frame construction. Part of this thesis contains drawings documenting the above mentioned changes.
The study of the behavior of track chassis using dynamic simulation
Hudec, Karel ; Kašpárek, Jaroslav (referee) ; Jonák, Martin (advisor)
This thesis deals with the study of the undercarriage, their components and organization. Further, this work is focused on selected types of machines with tracked chassis moving in forestry or for operation in forest ground. The second part of the thesis deals with the design of the tracked chassis for the forwarder and the subsequent verification of the functionalities by dynamic simulation.
Frequency Stability Assessment of Continental Europe Synchronous Area on Equivalent Model
Macejko, Stanislav ; Hába, Tomáš (referee) ; Koudelka, Jan (advisor)
This thesis deals with frequency stability, system disturbances and their dynamic simulation. The aim of the work was to create a single-machine equivalent and single node model for the simulation of the system disturbance from January, 8, 2021 in MODES network simulator. The thesis describes in detail created models and achieved simulation results, which are the frequency deviation waveforms. The simulation results are compared with the actual behaviour of the power system. The thesis further discusses the use of the models and suggests further improvements.
Simulation of CNC machine tool spindle in ADAMS software
Pham, Jakub ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
The bachelor thesis deals with the design of a simulation model of a CNC machine tool in MSC ADAMS software. Nowadays, simulations have become an integral part of every development process, as they offer a cost-effective alternative to classical machine development involving prototyping. Within machine tools, dynamic simulation of machine nodes is one of the unexplored areas. The aim of this work is to verify their functionality and reliability in this area. Within the scope of the bachelor thesis, a research on dynamic system simulations, the finite element method and the simulation software MSC Adams and Ansys has been carried out. In the practical part, the spindle loading of the MCV 754 Quick machine tool was designed. Subsequently, the model geometry and boundary conditions were determined and the spindle was simulated during the cutting process in MSC ADAMS. The simulation results were verified by both analytical calculation and experimental measurements on the machine. Furthermore, the concept of further development of the model within the framework of cosimulation was presented. Finally, all output parameters were compared and evaluated.
Predictive Simulation as a Tool for Decision Making Support
Horák, Michal ; Hruška, Tomáš (referee) ; Videcká, Zdeňka (advisor)
The bachelor's thesis focuses on analysis and optimization of the assembly line of gear pumps. The bachelor's thesis contains a suggestions for changes on this assembly line in order to balance the line and optimize utilization of operators on the line. The solution uses a dynamic simulation model that corresponds with the real state of the line. The simulation model is further used for experiments and selection of the ideal solution with respect to the selected objectives
Robotic table football - system integration
Švanda, Ondřej ; Lacko, Branislav (referee) ; Lang, Stanislav (advisor)
The aim of this bachelor’s thesis is to improve the current solution of a robotic table football, which arose as a part of students’ theses at the B&R Automation company. The paper focuses on a system integration of particular solutions of the whole robotic football project, using a modular design approach, and the creation of a user interface, including a visualisation of the ball’s and players’ position on the screen. The paper also includes a creation of a dynamic computer simulation to test the game strategy.
Hooclift NKH 8A340
Doleček, Ladislav ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis analyses hook loader NKH 8A340. For calculation of load states was used the dynamic simulation in program MSC.ADAMS. This results were used like a input data to solve the construction with finished element method. After evaluation of results were made design changes of hook loader. Part of this thesis contains drawings of modified parts of hook loader.
