Academic literature on the topic 'Brzdné systémy'

Summary: The State of and Needs for Research on Weapons in the Przeworsk Culture and in Pomerania in the Late Pre-Roman Iron Age Militaria are one of the most numerous groups of finds in Poland dated to the Pre-Roman Period. This category of sources has recently been a subject of two comprehensive studies: on the Przeworsk culture (Bochnak 2005) and the entirety of Poland (Łuczkiewicz 2006). These works, despite some differences resulting from the adopted methodology, systematised the material in the morphological and typological as well as chronological and cultural terms. However, the database has grown significantly in the last 15 years. There is a lot of information about new sites with weapons (at least 34); many sites (new and already known) were also published, e.g. Oblin, Siemiechów, Kuny, Gola, Wyszków-Zakręzie, Pajewo-Szwelice, Legionowo, Ruszków Pierwszy, Oronne, Gołębiewo, Nowy Targ, Malbork-Wielbark (pre-war research).However, the extremely important cemeteries in Zadowice, Niechmirów-Mała Wieś, Lemany, Modła, Glinki, Korytnica, Masów, and from Pomerania: Czarnówko, Brzyno, Wyczechowo, Żukczyn, Różyny and above all Gostkowo and Pruszcz Gdański, site 7, are still awaiting publication.After cataloguing the source database, organizing the material, and typological studies (the culmination of which were the two previously mentioned works), different areas of research are now dominant in the studies on armaments from Polish territory from the Late Pre-Roman Iron Age. The conference Waffen – Gewalt – Krieg (Wefers et alii 2015) has reviewed and summarised the topic. There is a lively discussion in the literature on the issue of armaments as an indicator for supra-regional contacts, as well as links with the Celtic world and imports from that zone. Various groups of military items (most often double-edged swords and their scabbards) are being analysed, as well as their distribution and influx routes. Also hotly debated is the general issue of the share of weapons of a foreign origin in the armaments of the population from the current Polish territory in the Pre-Roman Period.Another discussed issue is the importance of armament in the funeral rites, i.e.in the belief systems of the Przeworsk culture population. The weaponry is also used for sociological analyses, in terms of its importance for the world of the living, as a determinant of the status and social position of its owners during life and after death. The issue of the internal structure of warrior groups in the entire zone of the Baltic Sea was also extensively studied. Finally, the issues of the possible scale and scope of local arms production in the Przeworsk culture and Pomerania region were raised.As a postulate for the future, one should above all emphasise the need for continuous publication of the sources – new and archival ones. It is still possible to supplement or improve the existing typological systems, in the first place – that of spearheads. It is advisable to intensify research on the mechanisms behind the influx of foreign weapons, also in terms of sociology and ethnology. Militaria are still to be fully integrated into the study of social diversity and structure, as well as in the research of crafts and manufacturing in Poland in the Late Pre-Roman Iron Age.

This Master´s thesis deals with construction design of break system of the tractor Zetor Forterra HSX. At the beginning, there is an overview of different possibilities breaking system from other world´s producers of tractors. Afterwards there is constructional working from selection variant of suspension to final project. In this case the thesis contains required calculations of the whole device. Thesis also contains the stress and strain analysis of selected components of construction using a numerical approach of finite element method and drawing documentation of the selected components.

This master’s thesis focused on the issue of the possible conversion of liquid brake systems, in the form of replacement of wheel brakes. The first part focused on the function and description of the construction of different types of brakes. The second part is focused on description the types of brake system testing and the regulations regarding brake systems. The last part focused on the measurement of both vehicles and comparison of the results with the calculations.

Objective of this thesis is design of brake system of new car Formula Student class – Dragon 3. This car was built by students of faculty of mechanical engineering on Brno university of technology. Brake parts selection is described as well as designing hydraulic brake line circuits optimized for stable braking behavior on tracks of Formula Student competitions. One of main parts of this thesis is design of front and rear custom brake discs with related parts. These parts are FEM analyzed. In the end the whole brake system fitted on Dragon 3 car is tested on track and its performance is analyzed too.

This diploma thesis is engaged in analysis of braking process of vehicles, especially heavy utility vehicles, with regard to their instantaneous weight. This thesis features survey and division of braking systems and function of brakes including schemes and descriptions. Also there is introduce of some systems improving vehicle properties. Furthermore this work puts mind to possibilities of examination of brakes, measurement of braking distance and braking retardation namely in brake test rooms or by outdoor driving tests including descriptions of particular methods and equipment. There is also mention about legislative requirements for braking distance and braking retardation. The conclusion of this thesis compares numerically predicted braking distance and real braking distance measured for factual vehicle during outdoor driving test

Design of braking system for the formula student car. Calculation of basic forces acting in the braking system, including the design of hydraulic circuits. Mechanical analysis of the most important parts of the braking system and pedal assembly. Thermal analysis of the brake discs. Manufacturing and total cost calculation.

The diploma thesis describes the measurement and evaluation of braking traces in cars equipped by system ABS. The result of the work should contribute to improving the quality of photodocumentation of braking traces. To creating a procedure to eliminate as much as possible the loss of information during tracking documentation.

This work is engaged in the confrontation of the existing braking system of Formula SAE project. From made confrontations is selected the best solution and make his dimension and own construct design. It is verify through analyse of tension and analyse of heat transfer.

This diploma thesis is focused on conversion of Skoda Octavia RS mark I brake system. This vehicle will be used for race use. The aim of the thesis is to design adequate components of the brake system to achieve good brake deceleration and so that the design will be correspond to hard conditions on the race track. Thesis contains complete design of hydraulic system including control and brake forces, pressures, options of brake forces management and evaluate of brake stability. Followed by the design of brake caliper adapters and the static structural analysis by FEM. The thesis contains picture and assembly drawing attachment too.

Describe entire information about design of respective component in Formula (category Student) braking system is object of this thesis. Processing is divided to four main areas. The first one describes basic components in braking system, which goes on analysis of braking system in present used Formula Student Dragon 1. The second one, more spread part, consists of braking system proportioning for Formula Student Dragon 2, respecting pieces of knowledge from first generation Formula. The third part involves design single components of braking system for second generation Formula. This design is supported by measurements and results of calculations. The conclusion of master thesis involves design of caliper model and its FEM analysis.

This thesis studies the design of an electro-hydraulic landing gear and brakes control system of a trainer aeroplane. In the first part there is a basic draft of the landing gear kinematics and its loads during gear retraction, flight and landing. Braking conditions are also analysed. The thesis then focuses on the design of hydraulic circuits and their control. Simulations for studying the dynamic characteristics of the braking proportional valve and the course of plane braking were created in Simulink. There is also a brief section about reliability of the proposed system.
