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.
Vehicle Hydropneumatic Suspension

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.

Koudelka, Roman ; Janeček, Vladimír (advisor) ; Bažant, Václav (referee)
The objective of this theses was to conduct an inventory of the trees in the Čeřovka urban forest of the city of Jičín. Collected data were entered into the inventory table which contains information about taxon, girth, stem diameter, hight of individuals, hight of the crown's origin, diameter of the crown, growth stage, age estimate, health condition, vitality, gardening value and damage. Having regard to the above mentioned, I suggested the measures to improve the operational safety and the condition of the trees and I drew a layout of the individuals and groups of trees. The project also includes mapping of the public furniture and path and track network with suggestions for improvements. The thesis will provide The Jičín´s Municipal office a background for management of the urban forest.
