Abstract: With the development of contemporary drive systems that
have a lower or zero emission of exhaust products, a significant
reduction in the harmful influence of traffic on the environment has
been achieved, but today new pollutants have been identified on the
vehicle. One of such non-exhaust pollutant are brakes whose wear can be
a significant particulate matter (PM) contributor. Examining the
mechanisms of the formation of particles during braking, and therefore,
brake wear is becoming one of the important areas of research today.
There are several tests and driving cycles that are applied during the
research of the brakes, but they are not primarily defined for testing
particle emissions during braking. UNECE (United Nations Economic
Commission for Europe) has included in its plan the introduction of
standardised cycles that will prescribe a brake cycle whose purpose will
be to examine the formation of particles. The brake pads are made of a
mixture of different materials that ensure the longevity and efficiency
of the brake system and the applied materials have different wear
intensities in certain operating conditions. The most common laboratory
tests in this area are performed using inertial brake dynamometers. This
paper presents an experimental planning method of quantifying the
influence of some of the operating parameters (initial speed of the
vehicle, braking pressure and vehicle’s load per one brake disc-pads
friction pair) on the airborne particulate matter for four different
brake pads materials during testing on an inertial brake dynamometer.
Keywords: wear particles, brake dynamometer, testing, disc
brakes, driving cycle.
