Energetic model of linear axis with ball screw and servodrive
Sládek, Vojtěch ; Tůma, Jiří (referee) ; Huzlík, Rostislav (advisor)
The aim of the thesis was to study the Energy Models of Linear Axes with Ball Screws and Servo Drives, to analyze the individual parts of the axis with respect to losses, the methodology of calculating the losses on the electrical part and the mechanical part of the drive and creating a complex algorithm that calculates the energy consumed for the specified motion. The thesis is divided into a theoretical and practical part, where the theoretical part is divided into the treatise on the electrical part of the axis and its losses and the part that deals with the mechanical part and its losses. The calculation is divided into the basic verification algorithm and the calculation on the given example. Each calculation is calculated for both linear acceleration and S-curve acceleration. For both types of acceleration, the result of energy and its course over time is also the waveforms of position, velocity, acceleration, angular acceleration, moments, powers, power, speed and currents over time.

Non-contact temperature measurement
Sládek, Vojtěch ; Minář, Petr (referee) ; Hermanský, Dominik (advisor)
The aim of the thesis was the study of non-contact temperature measurement and the use of this measurement in the field of production machines. The first part of thesis includes concepts and definitions that are necessary for familiarization with the issue. In the second, practical part, contact and non-contact measurements were compared in two experiments. In the first one the machine frame was measured, on which the thermal load was simulated, the emission was determined, which was compared with emissivity from the tables. In the second experiment, the temperature gradient of the ball screw was measured during the ball screw operation and was determined emissivity, which was again compared with the table values. The conclusion of the thesis summarizes advantages and disadvantages of non-contact measurements that have been verified in practice.
