FAILURE ANALYSIS OF LIGHT COMMERCIAL VEHICLES' BRAKING SYSTEM

The description of the fault tree analysis is given in the introductory part of the paper, and it is pointed out the significance of the system for braking motor vehicles on the safety of people in traffic. A brief overview of the methodology of this method is then followed. The basic structure and the function of each subsystem during realization of given tasks are given in the part of the paper related to the brake system. Considering the example of the total failure of the brake system, it has been shown how to acquire a block-diagram of the observed system's reliability based on the formed fault tree. In order to be acquainted with the brake system from the aspect of failure occurrence and to record the largest possible number of potential failure modes of the constituent elements, the fault tree for the peak event "Reduction of the performance of the brake system" has been formed. In conclusion, the paper presents possible applications of the achieved results.
