Abstract
EN: SC "Ukrzaliznytsia" purchased the first of three planned regional three-car
(two main motor cars and one intermediate) diesel train DPKr-3 manufactured by
PJSC “Kryukovsky railway car building works”. To confirm the declared
characteristics and safety indicators of the DPKr-3 diesel train, specialists department
of Cars of Dnipro National University of Railway Transport named after Academician
V. Lazaryan conducted complex certification tests, which confirmed the compliance
of the stated parameters. One of the points of the Terms of Reference was to determine
the brake pressure of the linings per 100 weight of the train in terms of cast iron brake
pads. For this purpose, according to the methodology adopted in the territory of the
former CIS, force sensors, which were installed in the tick mechanisms instead of the
brake linings, measured the magnitudes of the forces of pressing the brake linings on
the disks. However, during the tests it was found out that the current standards for
calculating the provision of train brakes cannot be applied to modern rolling stock. It
is recommended for rolling stock where the use of brake pads, and even more cast
iron, is not provided by the design, to develop normative documents that would
determine the standards for brakes by the results of calculations and tests.
