Hodnocení spolehlivosti brzdového systému lokomotivy ve vztahu k požární bezpečnosti

Abstract

This master thesis deals with the running capability of a vehicle in case of fire, especially with the functionality of the automatic brake. The introductory part of this thesis introduces the vehicle, on which the function of the automatic brake is being analyzed, and the requirements for individual parts of the automatic brake regarding fire resistance according to the ČSN EN 50 553. The thesis includes the analysis of the individual parts of the brake which records the non-compliant components regarding the fire resistance. This thesis furthermore includes the analysis of risks, which can arise in case the automatic brake loses its functionality, and an FTA analysis of fault conditions in relation to fire on vehicle. Based on the FTA analysis, the measures were suggested to increase the fire safety of the vehicle, and follow-up FMEA analysis of forms and results of defects was made. The last part of this thesis evaluates the recommended suggested measures, and, by calculation, shows the significance of the fire safety on railway vehicles.
