DISC BRAKE FAILURE ANALYSIS OF THE MOTOR VEHICLE BRAKING SYSTEM

Abstract

The braking system of motor vehicles holds paramount importance for their active safety in traffic. Disk Brakes, being the executive components of the braking system, are the most critical units in terms of reliability and safety of operation due to their operational conditions. It is crucial to analyse all potential failure modes of disc brake components and ascertain their causes and consequences. The Fault Tree Analysis (FTA) method was used for the qualitative analysis of the disc brake component failures. FTA is a deductive method that establishes connections between the top-level failure event of the object under consideration and the basic failure events of its constituent elements. The fault tree of the disc brake was developed based on a detailed analysis of the object\s structure, the functioning of individual elements, operational conditions, a failure data during exploitation, and other pertinent information. The developed fault tree forms the foundation for conducting reliability and safety analyses of a quantitative nature. The conclusion underscores the significance of applying reliability theory methods and discusses the potential applications of the obtained results.
