Sensitivity analysis of FE model of a crash test
Jančář, Radek ; Řehák, Kamil (referee) ; Dlugoš, Jozef (advisor)
The deformation of the vehicle as a result of the accident serves as the input for determining the impact speed for the purposes of the expert report. One possibility of calculating the impact speed is by means of a verified finite element analysis (FEA) of the vehicle impact. However, to develop such a sufficiently accurate finite element model requires a significant financial and time investment. Such a model contains a number of key simplifications that are difficult to detect without prior experience. Fortunately, there are at least a few freely available detailed finite element (FE) vehicle models that have been experimentally verified. On these it is possible to investigate the effect of different modelling methods on observed parameters such as overall deformation or overall vehicle stiffness. Specifically, this thesis investigates the effect of geometric resolution level details, material model parameters, and boundary condition settings for the FE model of the Chevrolet Silverado 1500, model year 2014.

Extrication of Persons Trapped in Crashed Vehicles with Respect to their Construction
Pirner, Adam ; Kupka, Petr (referee) ; Vémola, Aleš (advisor)
This thesis deals with the topic of extrication of people trapped incrashed vehicles regarding the construction of the vehicle. Part of the resources needed for this theses was taken from a literary survey drawn up with the help of the Research and scientific library in Hradec Králové according to the given topic and key phrases. The first part of the thesis deals with specific parts of the constructions of cars. This part is followed by description of road accidents, various kinds of accidents and possible deformations of cars after accidents. The thesis deals with extrication itself made by fire brigades, suitable procedures, kinds of interventions and means of used technical equipment. Another part suggests ways of saving trails and evidence during road accident interventions. Final part of the thesis is focused on overall analysis of the given problem based on personal experience, suggestions, negative aspects of the current situation and differences in training of possible situations with reality at the site of the accident.
