Tractor Shift Mechanism Analysis
Netopil, Jan ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis focuses on the shifting mechanisms of manually shifted tractor transmissions. It provides a comprehensive overview of all significant structural nodes of the shift mechanism with an analysis of the influence of the structure on the resulting intensity of a force required for shifting. The main aim of this thesis is the design and validation of experimental equipment for measuring the force effects of the shift mechanism of a mass-produced tractor in actual operation. The design of the experimental equipment is based on a study of the used measuring technique and similar experimental equipment. The final structure is selected based on selection by the method of weighted values, taking into consideration the requirements of the structure. A functional measuring chain is designed and formed for the realization of the measurement. To evaluate the data from the technical experiment, a multibody model of the designed experimental device is created in the MSC Adams View software, through which the real parameters of the shift mechanism are obtained from the measured values. The designed experimental equipment brings the possibility of complete analysis and subsequent optimization of the tractor's shift mechanism

Design of bonding system for PCB repairs
Burian, Jaroslav ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
The goal of this thesis is to design a device for PCB repairing, mainly for conductive traces and soldering pads. The design focuses on mechanical construction, control unit and controling of the whole device, which is semiautomatic. A great deal of emphasis is placed on the simplicity and versality of the construction. The teoretic part of this thesis is addressed to the printed circuit board and its repairs. There are presented existing devices for repairing of those defects in the second part. The next part is focused on the design itself in terms of mechanical construction and choosing electrical components. There is described controlling of these components. Part of making mechanical components follows. Last but not least, firmware, which controls whole machine is described there. Finally, the machine was tested in the repair process of the solder pad on the printed circuit board.

System for evaluation of upsetting test
Janečka, Dominik ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The thesis deals with the proposal of measurement system for evaluating upsetting test. The variables for evaluating the test are obtained by using sensors of measuring devices. The necessary magnitudes are force, track and temperature. For this purpose they were used sensors HBM R6C, HBM W50 and thermocouple type K. The sensor signals are amplified by measuring modules Dewetron and transferred to a PC by measuring card NI USB-6009. There are further processed by evaluation program DEWESoft 6.5. In a final part are performed a verification measurements to assess system function.
