APPLICATION OF THE METHODS OF THERMAL ANALYSIS IN THE STUDY OF THE INFLUENCE OF TEMPERATURE ON THE FRICTION BASIS OF THE BRAKE OF THE CAR
For establishing the technical causes of the emergence and development of fires automobile equipment, expert examination and investigation of various profiles. Fires do not take place only as a result of malicious acts, but often due to the education in the operating systems of the car of a combustible environment and appearance in it of ignition sources. Investigation of fires in vehicles is aimed at determination of the mechanism of ignition. The study of fire automobile presents great difficulties due to the compactness of knots and aggregates, the brevity of the process, but also because of the strong heat and the fierce impact is destroyed or heavily damaged tracking picture on objects-media. In the process of production of fire-technical examination, there are often tasks associated with the definition of a technical malfunction of the elements of the brake system, motor vehicles, which are in causal connection with occurrence of fire. Brake pads, which is an important component part of the brake system of the car, play a significant role in the traffic safety. In expert practice, there were cases, when the lock brake pads leads to heating of brake disks and drums with the subsequent emergence of burning. In this regard, the expert sets questions on the degree of overheating of the elements of the brake system. These questions can be solved using the method of thermal analysis, with the help of which explore the thermophysical parameters of friction basis of the brake pads. To conduct research using the methods of thermal analysis as the object was chosen as the basis of friction brake pads firm "Ferodo". By the results of the research found that, using the results of thermal analysis in the study of the damaged friction basis brake pads you can determine the degree of damage to the foundation and temperature of heating during the operation when determining the causes of the fire of the vehicle. In article results of researches of the fundamentals of friction brake pads firm "Ferodo" method of thermal analysis exposed and not exposed to thermal effects at different temperatures, with the aim of obtaining data for use in the production of fire-technical examination to establish the cause of the fire vehicles.
