Dynamic reliability by means of measurements data modeling approach and mathematical modeling approach

This paper is the estimation of the time dependent failure probability of a plate modelling a glued isolating joint of the track circuit isolation of the track section of the railway signalling; We present three methods for obtaining the dynamical reliability of this component. The first one is only based on measurements. The second one is based on a data reduction with modeling compensation. The third one is only based on damage modeling. The all-measurement method is the best on results but the more expensive. The mixed data-modeling gives less good results but sufficient but better for using. The all-theoretical modeling based on physics chemical and probability theory gives likely results but can be adjusted on some data before using.
