Comprehensive System for Road Accident Analysis - Collision Between Vehicle and Motorcycle
Slepánek, Petr ; Kolíbal, Zdeněk (referee) ; Drahotský, Ivo (referee) ; Kropáč, František (referee) ; Bradáč, Albert (advisor)
The thesis describes the problems of a complex system for analysis of road accidents, specifically the methodology for solving the collision between vehicle and motorcycle. There are statistics described motorcycle accidents, motorcycle safety features, the basic types of collision positions between vehicles and motorcycles, design methodology for solving with traffic accidents between vehicles and motorcycles. The work is performed a set of different measurements used to supplement and refine the input data for the analysis of road accidents involving motorcycles. The work contains data obtained from measurements.

The Influence of Modern Passive Safety Features in the Protection of a Vehicle's Occupants
Vostrejž, Jan ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
Thesis in the field of passive safety problems, traffic accidents and health outcomes of participants in road traffic accidents is aimed, inter alia, to create an overview of modern passive safety elements especially cars. The work deals with elements of the passive safety system and the impact on the crew vehicle. It describes the principle of operation, especially airbags, safety belts, belt pretensioner and it includes solution of limiters tensioning force in the safety belt and other elements that have the task of reducing the consequences of a traffic accident. The use of modern elements of passive safety provides increased protection for the crew and eliminates the formation injuries crew. The technical issue is therefore closely related to the healthcare industry and in particular the Court of medicine in the field of personal injury in relation to the types and characters of incidents, or by applying of the safety elements. There are also shown the actual road accidents in which were killed or injured members of crew with an analysis of the mechanism of injury with the use or non-use of safety elements.

Strain, stress and safety analysis of the car reinforcement frame
Dobeš, Martin ; Vosynek, Petr (referee) ; Vrbka, Jan (advisor)
This master thesis deals with the strain, stress and reliability analysis of the safety frame of racing car. The safety frame is a part of passive safety, which it becomes active in a case of impact. The safety frame makes a reinforcement of the car body and provides its sufficient stiffness. The first part of the master thesis is focused on determination of stress and strain states during the static loading tests and their analysis. The loading conditions are prescribed by homologation regulations of Fédération Internationale de l´Automobile (FIA). The problem is solved, making use of computational modeling utilizing the Finite Element Method (FEM). The first part of thesis is used for the stiffness and safety analysis under the static loading test. The second part deals with the effect of loading velocity on the stress and strain states using the computational modeling and solver LS-DYNA.

Chassis Electrical Systems
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Travelling by bus is very extended in present and safety return home is a wish of every passenger. Outcome of this bachelor work is a survey of the most used stability systems, used in cars and facilitating the work of drivers in critic situations. Among others, this work contains the survey of powers acting on a vehicle during the ride. This powers influence impending slippery road on aggravated adhesive conditions. Individual systems are described attentively and supplemented by illustrating pictures, which near this issue and facilitate the real idea of functionality. At the conclusion of this work is mentioned the theoretical suggestion for practical exercising of a subject automobile electrotechnics and also a referring is mentioned to my continuation in this dissertation.

Pedestrian Protection Systems in Car Collisions
Rupčík, Jan ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with the protection of pedestriáns in a collision with a vehicle. The first section describes the history of vehicle safety. The next section is focused on the evaluation safety of vehicles. The following sections are devoted to passive safety of vehicles and aktive systems prevent the vehicle strikes a pedestrian. The last section describes the objectively examina the effectiveness of systems.
