Shape Memory Alloys - Modelling of Non-linear Systems with Hysteresis
 Vašina, Michal ; Hrabovský, Miroslav (referee) ; Grepl, Robert (referee) ; Žalud, Luděk (advisor)
This work describes a possibility to use a shape memory alloy as a non-traditional actuator in a particular mechatronic system. The practical part of this work is dedicated to the experimental property verification of the chosen shape memory alloy and also to the design and realization of the new type of electrically controlled gabled valve that uses a shape memory alloy as an actuator. This valve is designed as a replacement of the traditional solution and is also integrated into McKibbens pneumatic muscle endcap. There are also results of practical functional verification of the designed gabled valve solution listed here, and the limited condition for its manufacturing and use is stated here. In the theoretical part of this work, firstly, the shape memory alloy and non-linear systems hysteresis type are discussed. Secondly a new particular solution is designed, which is based on a non-linear computational element, defined by goniometric cosine function. Finally, the properties of the designed solution are verified through the simulations and with the use of experimentally gained datas.
