Study of Model Parameters Influence on Vehicle Insurance Impact
Šandera, Petr ; Svída, David (referee) ; Ramík, Pavel (advisor)
The diploma thesis deals with basic test procedures conducted by companies Euro NCAP and RCAR. It focuses mainly on insurance impact and describes the creation of a model, simulation and crash on barrier. Moreover, it explores the influence of change of yield strength, thickness and hardening of material of energy-absorber on simulation of insurance impact, especially the amount of absorbed energy by energy-absorber.

Two-quadrant regulated power supply for laboratory purposes
Kalus, Jiří ; Vorel, Pavel (referee) ; Knobloch, Jan (advisor)
The main goal of the bachelor´s thesis is a suggestion of switching power supply with energy absorption for the case of two-quadrant load. The source includes of three parts: the power for the control circuit, single-converter and absorber of the recovered energy. Output power source is 400 W and output voltage 0 to 40 V, current +10 / - 10 A. This bachelor´s thesis deals with the first half of the circuit description and the second part there are analysis and the suggestion. Scheme and printed circuit cards are in attachment.

Development of the Impact Energy Absorber Made by Metal 3D Printing
Kraicinger, Vít ; Malý, Martin (referee) ; Vrána, Radek (advisor)
Today, variously profiled parts are mainly used for energy absorption. For special cases, precise components are designed, as in the case of Formula Student, where a deformation article with a honeycomb structure is used. This bachelor thesis is focused on the design of an impact energy absorber made by SLM technology and lattice structures. For the design itself, a comprehensive overview of current knowledge in the field of deformation zones, energy absorbers and researches dealing with energy absorption was created. Based on the study, the most suitable material to produce AlSi10Mg was selected. Subsequently, the appropriate type of grid (BCC) and all parameters of the lattice structure were determined. Two energy absorbers with different struts diameters (0.4 mm and 0.8 mm) and different grid sizes (4 mm and 8 mm) were modeled for the selected parameters. At the end of the work are two simplified calculations that show the predicted final values of the proposed absorbers and the stiffness of the layers of the lattice structure with graded density.
