Design of leg for crash test dummy
Maršálek, Petr ; Semela, Marek (referee) ; Bilík, Martin (advisor)
This thesis is devoted to the design model of the lower limbs crash test dummies. It describes how the dummy developed historically, what are currently available for crash tests, what they are made and what their future will be. The main motive of the work is to design a model of lower limb for crash tests, with emphasis on the human anatomy. The work is characterized by how the figurine is produced using the form from material Thermolyne Clear, wood as a substitute human bones and the agar substitutes such as human muscle.

Automotive neck injury indicators in relation to dummy - tram interaction
Ország, Artur ; Jelen, Karel (advisor) ; Tlapáková, Eva (referee)
Title: Automotive neck injury indicators in relation to dummy-tram interaction Objectives The aim of the work is to evaluate the performer crash tests between the dummy and the vehicle in terms of the thread of the health of the neck and to determine which type of tram creates the smallest risk of health of the neck (cervical spine) at the specified speeds. Methods: This diploma thesis is conducted in form of a pilot study. The first part of the work contains theoretical starting points regarding the discussed topic. The second part analyzes the results of the crash tests and answers the research questions and examines the given hypotheses. Results: The most dangerous, concerning the structure of the neck, were collisions in the highest speed - 20 km/h. The highest values and highest probability of injuries with AIS 2+ and 3+ value were measured in this speed. The type of tram that was most dangerous for the structure of the next were T3 and KT8 and the least dangerous was 15T. Keywords: Tram, tram transport, neck, neck injury, crash tests, injury criteria, neck structure

Crash-Test Data Analysis - Frontal Impacts
Mikulášková, Lucie ; Ptáček, Petr (referee) ; Bradáč, Albert (advisor)
In this thesis are solved the problematics of crash tests. It is focused primarily on front impacts with full or part overlap. In the introduction are described the best known methods used in forensic - engineering practice for determination of energy equivalent speed (EES). Exactly specified impact tests, which are part of passive safety, are being addressed by several organizations around the world. In the practical part of this diploma thesis are solved four frontal impact tests, which were documented with the participation of the Institute of Forensic Ingeneering BUT in Brno.. These impact tests were performed to capture and analyze the data, resulting in the deformation energy used for permanent damage to the vehicle. Subsequently, the EES parameters were set for each vehicle.

Design of a Crash-Test Dummy
Sedláčková, Martina ; Coufal, Tomáš (referee) ; Bilík, Martin (advisor)
The main objective of this thesis is construction of crash test dummy for vehicle-pedestrian crash tests. There is review of nowadays used crash test dummies types in the introduction of this thesis. This is followed by part describing construction itself. Chapter about construction begins by characterizing of used materials features in relation with real human body physiology. Main part of chapter is describing construction of crash test dummy’s skeleton and its individual components including 3D modelling and strength analysis. Thesis is finished by cost assessment.

Possible Materials for Crash-Test Dummy Construction
Pokorná, Veronika ; Coufal, Tomáš (referee) ; Bilík, Martin (advisor)
This diploma thesis is devoted to the possibility of using materials for crash test dummy construction. The thesis describes how crash test dummies evolved, what crash test dummies are currently available for crash test and what they are made of. The main aim of the diploma thesis is to design materials and process for production of a crash test dummy with human-like biofidelity. The thesis describes the way which the dummy will be manufactured using duralumin, rubber, alder wood and silicone polymer or agar.

Analysis and processing of measured data from crash tests
Klein, Martin ; Coufal, Tomáš (referee) ; Tokař, Stanislav (advisor)
This thesis presents four crash test of two cars, in which always a moving vehicle strikes with fully overlaid front part into the side part (cabin for passengers) of another stationary vehicle. Crash test were carried out to detect the impact parameters for use in the road accidents analysis. Experimentally measured data and the acquisition of documentation during crash tests were therefore analyzed in an appropriate manner in order to obtain relevant impact parameters. One of the main evaluated parameters was the deformation energy that has been used for the permanent damage to vehicles. In the forensic engineering practice for analyzing vehicle impacts is as a control parameter used EES (Energy Equivalent Speed), this parameter was counted according to measured values during crash tests.

Presentation of crash test results from the frontal small overlap crash test
Coufal, Tomáš ; Semela, Marek
This article presents an executed frontal small overlap crash test of two vehicles moving at a speed of approximately 43 km/h with the emphasis on the resulting crash parameters for application in traffic accident analyses. The experimentally measured data from the crash test were suitably analyzed and important crash parameters were obtained and applied in impact modelling by a simulation program Virtual Crash, which is used to analyse traffic accidents.

Crush Element Design at Vehicle RCAR Simulation
Rydlo, Tomáš ; Svída, David (referee) ; Ramík, Pavel (advisor)
The diploma thesis deals especially with basic crash test conducted by the organizations Euro NCAP and RCAR. On basis of RCAR standard for low speed crash test is designed crush element for a car Ford Taurus by using a virtual simulation. Thesis describes the selection, editing, and creating a finite element model and impact simulation to the barrier. The purpose was use a real vehicle, design into it a new crush element, try different shape and material implementation of crush element and make their comparison.

Safety of Škoda cars
Poláš, Maroš ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis focuses on the history and the safety of Škoda cars. The first part deals with the history of safety as well as the history of Škoda cars. The second part is divided into decades and there are described various car models in terms of their active and passive safety, as development of various security features, as well as the vehicles themselves from 1964 to 2015.
