SIMULATION METHOD OF PREDICTING SINGLE REPLACEMENTS OF RAILROAD SLEEPERS

SYMULACYJNA METODA PROGNOZOWANIA POJEDYNCZYCH WYMIAN PODKLADOW KOLEJOWYCH

It is suggested that not every single sleeper, found inoperative in a track, has to be replaced at once. As a criterion for single replacements a number d of neighboring ineffective sleepers is adopted. Appreciating the probabilistic nature of single replacements, a model of the process is constructed and a solution arrived at by means of computer simulation. Field observations show that the number a considerably influences the number of single replacements. Separate investigations are necessary in order to select specific values of d for given structural and maintenance conditions of the track. Some pilot tests on gage changes is a result of different thrusts and different number of ineffective sleepers show that the number d should rather be less than three.
