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.

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.

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.

Device for towing vehicles in crash tests
Šmalec, Petr ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
Bachelor thesis is focused on device for towing vehicles in crash tests. Deals, what the crash test is and clarify some independent organisation for occupant safety. Next is solved the problem of propulsion system for devices and tell us the propulsion systems used in the vehicle research centers. At the end of thesis concept of device for towing two vehicles against each other is designed.

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.

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.

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.

Computational Simulations in Automotive Safety
Krkoška, Kamil ; Svída, David (referee) ; Ramík, Pavel (advisor)
The goal of this bachelor thesis is to build up a compact overview of recent development in automotive safety, concrete methods and results reached in this branch. Here are briefly described solutions for improvement of active and passive safety and next is explained testing of these systems in crash tests and assessment of these tests by using biomechanical limits. Attention is also given to the usage and benefit of computational simulations. Next are described procedures of simulations and also software used for these simulations. Then there are mentioned examples of successful applications of computational simulations.

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.
