The influence of track characteristics on the stresses introduced in operation in the frame of the electric locomotive class 43, EC 3400 kW

Abstract

In order to carry out maintenance in accordance with the state of the system, the locomotives in operation should be equipped with a system to monitor the main parameters and characteristics of safe operation and minimum risk. This work presents the method of determining the strains and influencing the configuration of the track on specific strains in the case of operation of the electric locomotive class 43, 3400 kW (4620 hp). Two tensometric rosettes with three strain gauges each, from which signals were taken when the electric locomotive operated in operation on a set route, with a trainset. The area in which the transducers were installed was determined by a previous analysis of the locomotive beat. The signals taken from the tensometric transducers were processed by obtaining the main stresses from the assembly points of the brands. The results obtained, i.e. the main stresses were correlated with the geometric configuration of the rail.
