Draft block for dough processing
Novotný, Jan ; Vlašic, František (referee) ; Dvořáček, Jiří (advisor)
The Bachelor´s thesis deals with a structural design of a draft block of the placement of dough processing rollers, which are used for stiffening wheat dough in bakery lines intended for the production of common bakery products. The introduction gives a description of a bread and common bakery making production line. Next the thesis briefly deals with other possible dough-stiffening methods and with sanitary, structural and material requirements for food processing machinery. The structural part is devoted to a roller propulsion draft and a solution of a shift of one of the rollers. It contains a calculation of a worm gear, a load shaft calculation and a complete design documentary materials.

Design of universal rotary manipulator for positioning of weldments
Kračmar, Filip ; Kolíbal, Zdeněk (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with the design of rotary manipulator for positioning weldments, which could be 5000 mm long and weight 500 kg. The beginning of the thesis presents the research of welding manipulators which could be founded on the market. Three variants of the positioner are proposed in the next section. The resulting variant is optimized using strength analysis in ANSYS software. Furthermore, two variants of drive, by hand drive or electric motor, are presented. The manipulator is interconnected in a single part using a designed frame constructure. Critical points of the manipulator are checked by strength calculation. The final part contains the risk analysis of the proposed manipulator.

Design of a parking brake for vehicles powered by an electric motor
Kolčava, Jiří ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with issues in the field of latch parking brakes, specifically the control mechanism. The key element of the work was the structural design of this mechanism, which converts the rotary movement of the electric motor into the translational movement of the control member enabling the latch to be inserted and extended from the latch wheel. The research part describes the main components of the mechanism and a description of individual types of control. This is followed by the creation of four conceptual designs and the selection of the optimal solution using the method of weighted coefficients. The structural part contains analytical strength calculations of the chosen conceptual design, including the solution of the kinematics of the mechanism. This part also deals with the analysis of the torque from the activation spring depending on the rotation of the crank mechanism and the subsequent optimization of the electric motor. In the end, the analytical strength calculations of selected structural units are verified by FEM analysis to confirm the functionality of the mechanism.
