Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.

Assessment of impact of production inaccuracies on characteristic of a helical conus-shaped spring in compression
Sitte, David ; Majer, Zdeněk (referee) ; Burša, Jiří (advisor)
This bachelor thesis deals with the possible influence of production inaccuracies on the characteristics of the helical conus-shaped spring in compression. In the first part of the thesis there is a search for a given problem of the helical conus-shaped spring in compression calculation according to the algorithm created in the bachelor thesis „Určení charakteristiky kónické vinuté tlačné pružiny“ created by Libor Loveček. The remaining part of the thesis focuses on a concrete the helical conus-shaped spring in compression, namely on taking its variable pitch into consideration to achieve a better correspondence of the numerical model to the experimental characteristics.

Influence of changed shape and dimensions of a helical spring on its compression characteristic
Melichar, Marek ; Majer, Zdeněk (referee) ; Burša, Jiří (advisor)
The bachelor thesis deals with a change of a shape of a spring in order to facilitate its assembly in a gas boiler controller assembly. The introductory part deals with familiarization with the given issue. Then, based on the algorithm created in the bachelor thesis "Assessment of characteristic of a helical conus-shaped spring under compression" of Libor Loveček, the calculation program is adapted for calculating the existing conical spring and is further modified for other spring shapes. Accuracy of the created algorithms is verified by comparing the results with commercial computing programs. Based on the calculations, new shapes are designed, manufactured and experimentally tested. At the end of the thesis the possibility of usage of created alternative shapes is evaluated.

The use of air springs for race car
Blažek, Jakub ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
This diploma thesis studies the use of air springs for race car, precisely Formula Student race car. Research part of the thesis deals with choosing suitable air spring for given application. In practical part, there is computation of parameters for appropriate setting of air spring, so it will comply with the rules of Formula Student. There is also simulation of air spring functionality in real use.

Vehicle Hydropneumatic Suspension
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The main task of this bachelor’s thesis is introduction of readers with main principles of hydropneumatic suspension. The introductory part, which aims to outline the historical background of the system, continuously follows the description of the principle of its function. This part also contains the typical features of this suspension system. This type of suspension is used at different types of vehicles, the specific applications are mentioned in the next chapter. The last section is about designing suspension for special military vehicle.
