Design methodology for the selection of basic components of linear machine tool axes
Král, Stanislav ; Dosedla, Michal (referee) ; Holub, Michal (advisor)
The aim of the thesis is based on specified parameters positioning units, which include stroke (1m, 2m, 4m), load (5kg, 50kg, 500kg), you place the position accuracy (0.04 mm) and dynamic (maximum attainable speed 1.5 m / s), proposals to build a ball screw, linear motor, a toothed belt and toothed comb. For selected variants of positioning units to design a 3D model of positioning units. The proposed variations to compare and define their advantages / disadvantages, techno-economic comparison, the limit values of individual designs, etc. The work includes a search drive in positioning units, design units with toothed belt, a toothed comb, ball screw linear actuator, a calculated message of individual proposals then 3D design options for the ball screw and linear motor including drawings and assembly drawings.

Study of diaphragm pump with linear motor
Čejka, Pavel ; Uttendorfský, Petr (referee) ; Pochylý, František (advisor)
The diploma thesis is aimed at the constructional design of diaphragm pumps with a linear motor. This pump is supposed to be used in medicine for pumping the blood or as an artificial heart. The basic facts, which are focused on the function of the heart and artificial heart, are mentioned in the first parts of the thesis. The next parts describe the diaphragm pumps and the constructional ways of their diaphragm fixation. Furthermore, the basic calculations, describing the function of the pump, are derived there. The basic parameters of the pump are also calculated. The thesis also contains the description of the body pump construction, whose working room is optimized by CFD calculation before the pump is manufactured. The final part of the thesis is concentrated on the measurement evaluation of produced pump model.

Study of plunger pump with linear motor
Jáchym, Jan ; Uttendorfský, Petr (referee) ; Pochylý, František (advisor)
This thesis deals with study and design of plunger pump with linear motor. This pump can be used for blood pumping in heart surgery. The theoretical part of this thesis is focused on description of extracorporeal circuit, heart boosters and artificial heart. This thesis provides an overview of check valves which are used in heart surgery too. Basic equitations for pump design are derived and calculated in this thesis. The pump design and manufacturing by the 3D technology was made by previous results. Finally, in this thesis are compared theoretical results and experimental data.

Study of plunger pump with linear motor
Machát, Pavel ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
The aim of this thesis is an engineering design of plunger pump with linear motor. This type of pump is used especially for blood pumping in heart surgery. The theoretical part is focused on distribution of pumps, description of extracorporeal circuit and booster heart history. There are basic calculations derived, which describe plunger pump performance. Then varied designs of plunger pumps follows, which are differed in size, shape and application. Next part includes design of reverse valves and their CFD computation.

Modelling of linear power drive with DC motor for control purposes
Vrbka, Michal ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
In my diploma thesis, I developed the model of a linear actuator for the control purposes. The first part summarizes the literature research of currently available linear actuator systems. The work further describes some of the capabilities of the simulation environment Matlab which was used for the creation of the computer model of linear actuators. In the last part, this theoretical model is compared with already available physical model of the system.

Concept of linear motors measurement workplace
Knobloch, Jan ; Červinka, Dalibor (referee) ; Klíma, Bohumil (advisor)
Master’s thesis handles about measurement on linear motors. Acts about set of two linear machines on one rail. One is motor and second is load. Thesis paies their mathematical description, control and measurement. It’s made measurement of the linear motor load characteristic. Next measurement have to do with losses in the converter. Is chosen measuring instrument t for measurement during working cycle. During working cycle has determine power eciency of entire drive.

Position control of cross-table dedicated manufacturing machine
Plocek, Jaroslav ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis treats the drive solution of the two axis cross-table of a single-purpose manufacturing machine. The first chapter analyzes the concept of drives and compares different variants using either a direct linear drive or a ball screw with a rotary servo drive. The thesis further deals with sizing the motor and the power unit assembly and the description of the whole measuring system. The structure of cascading position controller, its description and the calculation of current and speed control loops is covered in the next part. The last section discusses practical settings of all control parameters.
