Active Damping of Machine Tool Head
Škúci, Michal ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
The master’s thesis deals with building mechatronics model of machine tool head delivered by company TOSHULIN,a.s. for purpose of damping vibration. Mechanical part of the model is based on modeling of system of flexible bodies. Components are modeled in FEM program ANSYS and subsequently reduced using Craig-Bampton method. The system of flexible bo-dies is created in MBS program ADAMS. Model is linearized and subsequently reduced. As a element of active damping is used linearized model of magnetic bearing. For control is desig-ned PID controller. The comparison of damped and undamped model is conducted in the end.

Active Vibration Damping/Chatter Control of Machine Tool Spindle Units
Škúci, Michal ; Blecha, Petr (referee) ; Březina, Tomáš (advisor)
This bachelor’s thesis describes the issue about machining, causes of spindle chatter and different ways of chatter damping. It evaluates advantages and disadvantages of different ways of damping. There was made and described simple simulation model on which searching simulations was made for purpose of receiving picture of behaviour of model for different parameters. Model of active damping was made too.
