Design of chamber for collection and measurement of particles formed by brake wear on an inertial brake dynamometer

Abstract

Collecting and measuring the concentration of particulate matter formed by brake wear, depending on the methodology used, can be a major challenge. There are a number of different sources of particles that are formed not by combustion in the IC engine, so it is necessary to separate and measure only the particles that are formed by the wear of the elements of the brake friction pairs. In the case of an inertial brake dynamometer, the chamber in which the brake is located is most often used, and in this way, it is possible to collect and measure only the particles created by the wear of the brake pads and disc. This paper presents and presents the chamber construction of an inertial brake dynamometer located and used at the Faculty of Engineering University of Kragujevac. The chamber is constructed based on requirements of planned tests and constructions applied to inertial brake dynamometers in various studies of authors around the world.
