Mechanical design the rotary joint of satellite antenna
Šreibr, Vít ; Mazal, Pavel (referee) ; Paloušek, David (advisor)
The aim of this bachelor thesis is a mechanical design of the rotary joint of the satellite antenna. It is a partial solution of the project which is dealing with a development of new product for a commercial subject. The device enables horizontal and vertical movement of the satellite. The established aims are solved in the whole range. The basic structure is conceived as a weldment. The other parts are connected with the body by demountable joints. The choice of key points is supported by calculations and the design is documented by technical drawings. This thesis is suitable for readers with an intermediate technical knowledge.

Mechanical design of the supporting frame for a satellite antenna system
Hrdonka, Štěpán ; Mazal, Pavel (referee) ; Paloušek, David (advisor)
The aim of the Bachelor thesis is to create a structural drawing of a satellite dish supporting frame. The supporting frame will allow the dish to be mounted on a car. A part of the project is also to create a drawing of a rotating mount that will allow the satellite parabole to rotate around its vertical axis. Construction of the frame is designed to withstand required wind load and to prevent its sag from fundamentally influencing the signal quality. The stress-strain analysis has been carried out by using the Finite Element Method (FEM). Under the influence of the moment of 440 N.m around the –x axis and of gravitational force of 442 N the final maximal sag was 1.6 mm. The rotating mount is constructed in a way that requires only minimal maintenance and is able to withstand adverse weather conditions. That was accomplished by a suitible selection of materials. As the thesis is a part of mobile satellite prototype development, the project is designed in a way considering the final price and easy installation. Another part of the thesis is to create drawing documentation.
