Development and weight reduction of central housing for commercial vehicles
Blecha, Martin ; Pittl, Michal (referee) ; Píštěk, Václav (advisor)
The theoretical part of the thesis is focused on the clarification of the central housing function and its placement in a truck. The central housing function and placement depend on a vehicle chassis design. There is the weight optimization of the housing which is solved in the practical part of the thesis. The optimization is based on strength calculations of the Finite Element Method. There are weight savings and financial savings evaluated at the end of the thesis.

Control of heating system for family house
Blecha, Martin ; Zezulka, František (referee) ; Štohl, Radek (advisor)
The aim of the work is design involvement of controls elements and implementation of the control program for control of heating system for family house. The first part deals with the analysis of control principles, sources of heat and radiator elements. It describes measuring control devices from KOBRA company, and software named “Architekt” which serves for environment creation. The second part focuses on the design diagrams, switchboard wiring, its installation and the creation of the application.

Design of a test rig for a wear test of inner ball joints
Blecha, Martin ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This diploma thesis deals with the design of several variants of test rig for tests of axial ball joints of passenger cars. The individual design variants are evaluated based on the evaluation matrix and then the best option is selected. Selected proposal includes a complete design including 3D models and strength analyses that focus on the most stressed construction nodes. These design nodes are solved using the finite element method. Hydraulics and hydraulic elements are equipped by the existing equipment from a test lab. At the end of this thesis is solved risk analysis of the new construction and its economic evaluation.

Laboratory demonstrator for vibrodiagnostics
Blecha, Martin ; Krejčí, Jakub (referee) ; Klusáček, Stanislav (advisor)
This thesis deals with a vibration diagnostics of objects, structures and machines. The theoretical part is divided into three chapters according to type of the measurement. The first part called Modal Analysis discusses the basis of vibration, methods of measurement, relevant technical equipment and principle of experimental modal analysis. The second and third chapters of the thesis are focused on the diagnosis of defects. Each chapter mentioned above describes diagnosed defects, used methods and procedure for the diagnosis. Another part of the thesis summarizes practical issues and results gained in the laboratory experiments. It begins with discovering parameters of the measured object using technical diagnostics – experimental modal analysis. In the next step the hardware concept design was created, including custom measuring application programmed in LabVIEW. One part of the design is the laboratory model which includes a structure for free mounting and a possibility of excitation by an electrodynamic exciter. The application is also modified to enable measurements with shaker excitation. Finally, applications cooperating with professional software ModalVIEW and BK Connect were developed in order to simplify the operation and increase the comfort.

Reconstruction of discharging shakeout machine electric installation
Bednář, Vojtěch ; Blecha, Martin (referee) ; Pazdera, Ivo (advisor)
This Diploma work is concerned with the design of project documentation for discharging shakeout machine electric installation. This work continues in the Semestral project 2 in which the background of a new machine was made. Then, this work deals with the replacement of a switch room with required devices including the design of a new connecting cables and power streams. In the first part, the work deals with the control part of the device and the design of control and signal cables including the product documentation of the device. In the second part, the work deals with the proposal of building electro installation in which a new lighting and its use is described. The last part focuses on the coordination during the realization of a suggested device. In this part, all problems coming from the particular working procedures including a proposal of possible solutions are described. According to the project documentation and following realization, the documentation of final concept reflecting the real status of the device is described.
