Conception of ATV (all-terrain vehicles)
Dosedla, Milan ; Vančura, Jan (referee) ; Porteš, Petr (advisor)
This thesis is review article of the current design and construction setup of ATVs. In the individual chapters are analyzed function of structural units and their advantages and disadvantages for the application. Much attention is paid to the design and construction of the brakes and axles. Work based on the analysis 30 models of ATVs from different manufacturers. This thesis reports the specifications of selected models. In conclusion we discuss the appropriateness of design solutions for different types of ATVs such as utility or sport models.

Suspensions of passenger and race cars
Ševčík, Jan ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
Bachelor thesis focuses on comparing different types of axles between them with emphasis on changing the geometry during propružení.In student version of Autodesk Inventor Professional was created virtual models of axles and virtual test polygon. The output of the program are a series of images showing the axle during springing. Changes in geometry are quoted, described and analyzed. In conclusion there are compared to civil rights and race suspension.

Race Car Suspension, Springing, Damping
Šťastný, Jan ; Zháňal, Lubor (referee) ; Blaťák, Ondřej (advisor)
The main subject of this bachelor project is overview of suspension, springing and damping methods structural design in racing car. Attention is payed especially to automotive races which are under sponsorship of ACR (Autoclub of Czech Republic). Firstly is placed issue which notify main sort and princip of suspension, springing and damping function. In the next chapter is summary of technological restrictions and prescripts for racing car structural design. Next chapter refers about the most used types of structural designs for given competition. The last chapter considers development trend of suspension, springing and damping systems in racing cars.

Compaction of ceramic nanoparticle suspensions by centrifugal forces
Mišák, Jiří ; Maca, Karel (referee) ; Trunec, Martin (advisor)
In bachelor’s thesis, there was researched compacting of ceramic suspensions prepared from aluminium oxide with particle size of 100 nm by centrifugal forces. The homogeneity of centrifuged bodies was described in dependence of the speed of centrifugation. It was shown, that homogenous plate samples with regular particle packing could be prepared from centrifuged bodies. The structure and sintering behaviour of such bodies were superior to samples prepared by cold isostatic pressing. Similar properties could be reached in samples prepared from suspension with high loading (47,5 vol.%) as well as with lower loading (20 vol.%). The advantage of regular and dense particle packing by centrifugal compaction was demonstrated by manufacturing of transparent ceramic samples.

Separation of rigid particles from heterogeneous suspension
Prax, Ondřej ; Debreczeni, Ondřej (referee) ; Pochylý, František (advisor)
The bachelor thesis contains a literature search dealing with the separation of solid particles from a heterogenic suspension. The first part is aimed at separation methods. Then, a chapter follows dealing with separation devices, which are used in waste water treatment plants. A more detailed description of the separator used for the separation of sand from waste waters is part of this paper. The described device serving to separate solid particles from a suspension uses the combination of sedimentation and separation methods. To visualize the separator a 3D model in Autodesk Inventor Professional 9 device was used in the presented paper.

Gelcasting of Advanced Ceramics
Veselý, Jan ; Maca, Karel (referee) ; Trunec, Martin (advisor)
In Bachelor thesis, a literary overview of gelcasting method was worked out and pursuant to this overview, composition of alumina suspension was optimised for fabrication of bulky and complex-shape ceramic part. Four variants of ceramic powder filling in suspensions were prepared. Based on the experiments, a suspension with powder loading of 47,5 vol. % was chosen. The ratio between linear and crosslinking monomers was investigated for this suspension. A suspension with monomer ratio of 4 : 1 (linear : crosslinking) was chosen for preparation of bulky and complex-shape ceramic part. Gelcasting was verified by fabrication of ceramic medal and a knee-joint.
