Mechanical and mathematical models of mechanical multidimensional discrete-continuous systems “carriage – track” in terms of static and impact interaction in a butt roughness zone are proposed. Their interaction is investigated with the example of a four-axle car and a track for four motion phases in the place of isolated butt roughness. Parameters of static and impact interaction of the carriage with a track in a place of butt joint which takes into account operational and constructive factors are defined.

When macrobodies undergo collision, macrocraters are formed for which the ratio of crater's depth to striker diameter does not exceed 10. At the end of the 70's, an anomalous effect of formation of microcraters with relative depth of about [10^2-10^4] of particle size has been detected. Analysis of the experimental results made it possible to reveal the existence of a narrow impact interaction zone within which craters-channels are produced with a good repeatability. Evidence of a limited relative depth under macroimpact is explained by restrictions imposed by energy intensity of impact interaction in a barrier material.
