Safety assessment of operator activities at the BASICTURN vertical turning center
Cunda, Ondřej ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The Master's thesis deals with the safety of operator activities at the BASICTURN vertical turning center. The first part is focused on the requirements arising from the directives of the European Parliament and the Council in relevant areas and a system analysis of the issue. The second part is a risk analysis related to operator activities on the operated machine.
Wood-splitting machines - security aspect
Láznička, David ; Zeizinger, Lukáš (referee) ; Malášek, Jiří (advisor)
The main goals of this bachelor thesis include development and critical research of splitting machines. The main focus is on manufacturers and types of log splitters, where their technical parameters, suitability for use and safety features protecting users are assessed. At the end of the work are the safety requirements set by the standard ČSN EN 609-1. Part of the work is also a 3D model of the splitting machine.
Design of Paper Shredders for Home Use
Tupá, Anna ; Rajlich, Jan (referee) ; Sládek, Josef (advisor)
The bachelor thesis is focused on the design of a home shredder with a waste container volume of 15 liters. Emphasis was placed mainly on variety of shapes, safety of use, instinctive control and design different from traditional solutions of shredding machines. The design is targeted at small offices or homes.
ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.

Probabilistic Approach for Assessment of Earthing System Design
Vyčítal, Václav ; Gurecký, Jiří (referee) ; Procházka, Karel (referee) ; Toman, Petr (advisor)
This dissertation thesis deals with application of probabilistic approach to assessment of earthing system safety in distribution networks, especially for cases with common earthing of high and low voltage side of distribution transformers HV/LV. In these cases, the increased potential during fault might be transferred from high voltage to low voltage network and thus the individuals from public can be exposed to increased risk. Thus, for these cases were in this thesis defined expectable touch scenarios together with the resulting risk imposed on individuals from the public. Based on the results it seems that adoption of probabilistic approach for these cases of earthing systems might be more suitable compared to the conventional deterministic worst case approach. In accordance to the aims of the thesis, a thorough analysis of currently adopted probabilistic approaches was carried out as well and it was pointed out to some new possible simplifications in the adopted probabilistic based methodologies. For example, it seems that appropriate modelling of human body resistance by the full lognormal distribution is not completely necessary and similar results can be obtained when only the resistance for 50 % of population together with c3 and c4 fibrillation curves are used. Much of the work was also devoted to the determination of possible uncertainty of calculated risk of evaluated earthing system, especially due to inappropriate modelling of earthing system. The appropriateness of different earthing system modelling methods together with other parameters on the value of calculated risk was investigated through conducting sensitivity analysis. Based on the analysis results it seems, that due to using more, or less simplified modelling method, a possible underrating in the resulting risk of about 40 % (about half an order/decade) is expectable. On the other hand, the change of parameters related directly to calculation of fibrillation probability seems to exhibit greater change in calculated risk by up to units of orders/decades.
