Dynamická analýza koleje / Dynamic Analysis of Track

Kulich, Pavel January 2017 (has links)
The diploma thesis deals with analytical description of vehicle - track dynamic interface. There are described basic analytical models which are subsequently extended in order to get a more precise description of dynamic phenomena. The aim is to compile a model that faithfully describes the dynamic phenomena in the track. These new compiled models are qualitatively compared with data obtained by measuring in the track.

Nelineární analýza bezstykové koleje v obloucích malého poloměru / Nonlinear analysis of continuous welded rail in curves of small radius

Murínová, Klára Unknown Date (has links)
The diploma thesis examines the influence of curve radius on continuous welded rail stability in a small radius curve. Attention is paid to curves with a radius less than 300 m. The first part of the thesis summarises the theory of continuous welded track and influence of track parameters on track stability. The second part of the thesis deals with constructing of the numerical model of a curved track with the observed behaviour of track under thermal loading with positive and negative temperature values. The variable values in the model are rail shapes and different radius. In the end, the shape of the track lateral deflection as a function of temperature are evaluated.

Plán krizové připravenosti pro Jihočeskou univerzitu v ČB - Koleje a menzy, zajišťující plnění opatření vyplývajících z krizového plánu kraje. / Plan of crisis dispositions for University of South Bohemia - Hall of residence and university canteen providing discharge of precautions following the county crisis plan.

JÍCHOVÁ, Marie January 2013 (has links)
During our lives, we encounter various situations which we must learn to face so that the impacts on the lives, health and the environment can be as small as possible. One of the means of help usable for the crisis management is to prepare emergency and crisis plans. Given the frequency of natural and anthropogenic threats the planning has become an essential part of our lives. After the amendment of Act No. 240/2000 Coll., on crisis management, the obligation to process emergency preparedness plans for individual entities ensuring implementation of the measures resulting from the emergency plan of the region was updated. For this reason, I have focused in my thesis on the development of the emergency preparedness plan for South Bohemian University Colleges and Canteens. In the theoretical part, I first explained some basic terms. I continued with the description of threads and risks along with the evaluation methods. I also focused on measures to protect population which are on a very good level in CR, some of them has even become a model for the neighbouring countries. I mentioned the crisis situations that are declared when an incident event grows into a crisis situation. Then, I formulated the role of state authorities, local government bodies, security councils and emergency committees. I closed up the theoretical knowledge with the issue of safety planning which aims to reduce the consequences of situation that endanger us. The theoretical part is followed by research conducted by the qualitative form of data collection. The main question that the thesis wants to answer is: What are the risks that endanger performance of the tasks arising from the crisis plan of the region to South Bohemian University in ČB ? Colleges and Canteens? As regards the methodology of the thesis, it was crucial to gather data needed for the processing of the emergency preparedness plan, which are achieved through controlled interviews with the Director of Colleges and University Canteens, safety officer of the University, Head of University Canteen, maintenance staff and through cooperation with the ČHMÚ. I obtained other relevant information through cooperation with the South Bohemian HZS which provided the necessary cooperation needed to prepare this plan. It mainly included information needed to analyze external threat. Then I analyzed the internal risks which could interfere with the function of the entity and thus performance of tasks from the regional emergency plan. At this stage it was necessary to examine the University College and Canteen buildings. When analyzing the risks I came to a conclusion that the operation of the South Bohemian University Colleges and Canteens may be discontinued by the following hazards: natural floods (only in the case of Colleges K5 and K6), special floods, road transport of dangerous substances, risks resulting from climatic conditions (snow calamity and long-lasting frosts, storms, hurricanes, torrential rains), building fires, gas leaks (endangering the buildings of Colleges K1, K2, K3 and Canteens where gas is used for cooking appliances), power supply failure, heat supply failure and failures in the supply of food and water. The thesis findings can serve not only to deal with crisis situations but they can also be used by South Bohemian University students as a source of information or a basis for other work aimed at e.g. creating suitable conditions and environment for communication with people affected by the crisis situation who were forced to leave their homes and temporarily stay in the buildings of the University Colleges and Canteens. As these events cause pressure on human mind it is necessary to provide assistance to these people.
