NUMERICAL METHODS OF DETERMINING DRY FRICTION FORCES IN THE SHOCK ABSORBERS OF A TRAIN

METODY NUMERYCZNE WYZNACZANIA SIL TARCIA SUCHEGO W AMORTYZATORACH POCIAGU

On the basis of a model in which the train is represented by a system of N masses connected by shock absorbers, the problem of determining the dry friction forces for zero slip velocities is considered, and the convergence of the numerical methods proposed for the solution of this problem is proven. The calculated solutions appear to be a very good approximation of the values measured in the experimental train.
