Design for testing device used to measure air leakage from linear pneumatic actuator
Kurillová, Katarína ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This thesis is focused on detecting air leakage in serial production of pneumatic linear actuators. Testing for air leakage is an important part of the production process in which the manufacturer ensures that the product satisfies quality requirements and works correctly. The thesis was created in collaboration with the Czech manufacturing plant of SMC Industrial Automation CZ s.r.o., which produces pneumatic actuators. Goal of the design part of the thesis is to select the most effective method for testing and finding universal principle for testing in specified conditions. The principle is then applied to design a testing device for the CQ2 cylinders. The testing device consists of three parts - pneumatic circuit, control circuit and electric circuit. Thesis conclusion contains comparison of the newly designed testing device with the device currently in use.

Localization and identification of damage type of pneumatic drives
Richter, Vladislav ; Dočkal, Aleš (referee) ; Mazal, Pavel (advisor)
Pneumatic drives are an integral part of many machinery, with high demands on their reliability. Unfortunately, they sometimes fail, either due to improper production or assembly at the factory or by gradual degradation of moving parts and sealing elements during operation. Current diagnostic methods do not allow localization or identification of the type of damage and do not allow the operator to make a qualified decision. This work deals with the use of acoustic emission for these purposes. On PB type cylinders manufactured by Poličské strojírny a.s., a methodology is introduced which leads to the direct identification or at least localization of selected defects. By implementing this methodology in the final inspection of the production plant, the percentage of exposed pieces of waste will be increased, thus preventing accidents of these faulty pieces during operation.

New uncommon actuators in robotics
Fogelton, Lukáš ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
This report presents up to now development of actuators in robotics theirs applications, specifics various sorts of actuators, theirs principles, advantages and disadvantages. Report is splitted to the part that presents usual used actuators, especially electric principle powered actuators, today primarily PMSM motors, furthermore pneumatic or hydraulic actuators that uses pistons principle for convert pressure energy to the motion, or piston combustion engines. In next part presents more unusual actuators that have interesting features for use. Lot of these actuators are elastic, deformable and have better power/weight ratio. In the last part is presented priciple of function pneumatic stepper motor, that is uncommon actuator useable for application in robot works compatible with magnetic resonance imaging.

Design and implementation of a pneumatic educational model
Javorek, David ; Dobossy, Barnabás (referee) ; Najman, Jan (advisor)
The bachelor thesis deals with creating an educational pneumatic model and its subsequent simulation. The research section describes the possibilities and types of control of pneumatic actuators. Furthermore, their modelling in Simulink using Simscape blocks is explained here. In the practical part of the work is given the procedure of creating an educational model, how their control and data collection from sensors is solved. Finally, the modelling of the simulation is explained.
