Sedlář, Jiří ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
In this thesis there is mentioned the overview of types of axles, which are used by the current cars.Their working principle is described for each type of axle and it is also mentioned an example of usage for concrete car. In the thesis are listed marks and types of cars, which use this types of axles.

Vibration damper development and innovation of a laboratory stand
Filipi, Jaroslav ; Mazůrek, Ivan (referee) ; Nevrlý, Josef (advisor)
Bachelor work deals with description and functionality of vibration dampers. Since the vibration dampers is a wealth of species, work is focusing on the dampers used in cars known as shock absorbers suspension. I have described conventional shock absorbers suspension and modern shock absorbers suspension. Furthermore, I described active chassis. High-quality equipment is very important for the future development of dampers. I propose possible ways of innovation existing laboratory stand.

Production and Examination of Foam Ceramic Filters
Ondrášek, Jan ; Sokolář, Radomír (referee) ; Nevřivová, Lenka (advisor)
The aim of this thesis is to describe manufacture of the ceramic foam filters and its materials. Thesis includes description of manufacture of ceramic shard, properties of ceramic suspension and testing carried out not only on materials, but also on fired ceramic filter. Furthermore this thesis includes experimental part which includes evaluation of influence of viscosity on final firmness of the filter and its contraction by desiccation and firing.

Povaha toku modelových suspenzí
Kulaviak, Lukáš ; Večeř, Marek ; Růžička, Marek ; Drahoš, Jiří ; Hladil, Jindřich
The main object of the present investigation is to test the settling abilities of mixtures of solid particles in liquids. The key quantity here is the magnitude of the viscosity, both of the carrying liquid (water-glycerol solutions) and the effective viscosity of the two-phase mixture. Few model systems were used (glass and polystyrene pellets), to study the settling process. The sedimentation were recorded by a video camera and the resulting deposit structure was photographed. Besides, also a real suspension was tested, of geological materials (calcite, quartz, mixed geological powder, etc.). Immersion rotary viscometer Brookfield with special spindles (RVT and V spindles) was used to measure the effective viscosity of the dispersion.

Viskozitní charakteristiky geologických suspenzí
Kulaviak, Lukáš ; Večeř, Marek ; Růžička, Marek ; Drahoš, Jiří ; Hladil, Jindřich
The system under study was real geological suspension – ground sedimentary rocks of different chemical composition (calcite, quartz, etc.) dispersed in water-glycerol solutions. The reference one-phase system was a Newtonian liquid (glycerine with water). It is problematic to measure the rheology of settling suspensions, so some specific tools must be used. We used the rotating vane rheometry, with the immersion viscometer Brookfield and two spindles V-71 and V-72. The basic rheological data of solid-liquid system are displayed as flow and effective viscosity curves. The obtained results on rheology were related to the settling behaviour of the geological mixtures, namely to the certain kind of the lateral instability.
