Abstract
The results of comparative traction-energy tests of a 3ES5K locomotive with axial traction control, equipped with a friction activation device (FAD), with a locomotive of the 3ES5K series with axial control, not equipped with a FAD friction activation device, are presented.
The locomotives were tested at the head of freight trains weighing 7,078 tons and 7,101 tons on the Krasnoyarsk – Vostochny – Ilanskaya station section of the East Siberian Traction Directorate. A comparative assessment of the traction and coupling properties of the 3ES5K series locomotive No. 1147, equipped with a locomotive friction activation device, and the 3ES5K series locomotive No. 1271, not equipped with a FAD, was carried out during the analysis of the parameters recorded by traction and energy laboratories. The parameters were recorded when the locomotives were moving along the sections of the limiting grades of the tracks. Based on the results of processing data from control runs of the tested locomotives, it was found that the traction and coupling properties of locomotives during tests under identical conditions were higher for experimental 3ES5K electric locomotive No. 1147 equipped with a FAD, than for control electric locomotive No. 1271 not equipped with a FAD.
Based on the test results, conclusions were drawn about the movement of trains along the sections of the route and the limiting ascents. A comparison of the obtained experimental data is carried out.
