DEFINITION OF THE ZONES OF ESTIMATION OF A PROBABILITY OF WHEELSET SKIDDING
Abstract
The author continues the study (see MT Journal 2009 vol.2) on dependencies of the structure of elementary events on probability of wheelset skidding of a freight railway car and presents a definition of the zones of estimation of probability of the events preceding skidding. The difference (Δψ) (based on the dependencies of standard calculation of automatic brake) between a calculated and a real creep coefficient is grounded as a parameter, defining conditions of the beginning of wheelset skidding, caused by reduced creep coefficient, wheelset unloading, off-nominal displacement of spring-mounted parts of a wagon (events A, B, C respectively). The parameter Δψ serves to formalize the conditions causing the events A, B, C.
