Abstract.
The authors consider the issues of control of the latent period of changes in the technical condition of railroad
tracks in their hazardous and potentially hazardous sections. It is noted that the use of traditional methods of signal processing in such
sections does not make it possible to adequately assess the situation due to the level of noise in the vibration signals. It is shown that
using the higher-order moments of the noise, it is possible to identify the latent period of the initiation of a malfunction on railroad
tracks and determine the dynamics of its development in time.
Keywords
: potentially dangerous section, vibration, noise, higher-order moments, noise control.
Introduction
Railroad systems are known to be constantly exposed to various kinds of unfavorable industrial and natural
processes. As a result of the negative impact of these processes, not only the physical and mechanical properties of the
railroad tracks themselves change, but also the structures on which they are located, for instance, bridges, tunnels, etc.
Existing monitoring systems need to monitor emerging track faults, determine the dynamics of their development, analyze
the cause of their occurrence, the recurrence of the situation, etc. and to register hazardous and potentially hazardous
sections of railroad tracks as a result of collecting and processing statistical data [1, 2].
Tracks that run through seismic zones, permafrost, along river banks, sea shores and other bodies of water, etc.
are considered hazardous sections. These sections of the route are under constant surveillance. Potentially hazardous
locations may emerge, for instance, in sections of a continuous welded track [2]. A number of studies [1, 2] are devoted
to the identification and localization of such areas, and there are also recommendations for their elimination. However,
the question of identifying the latent period of the occurrence of malfunctions in potentially hazardous areas, as well as
determining the dynamics of their development, remains open. The use of traditional methods of signal processing does
not ensure the required quality and efficiency, since the occurrence of a malfunction is accompanied by the emergence of
the noise that distorts the results of vibration signals processing. In this paper, one of the possible options for solving this
problem is proposed as a result of calculating the higher-order moments of the noise of noisy vibration signals based on
a set of controlled parameters.
