Automation of designing the longitudinal profile of hump yars with application of spline methods
Some issues of the automation int designing the longitudinal profile of the down grade part of a hump yard with application of spline methods and in particular the cubic spline of Defect 1 are examined. It is shown that the application of cubic spline models of longitudinal profiles even in the stage of designing enables forecasting formation of defects on the down grade part of hump yards in the places where longitudinal profile elements with a great algebraic difference mate. It also enables obtaining their new service performance. It becomes possible to analyze the existing longitudinal profiles of operating hump yards basing on their leveling data and to work out well-founded recommendations to improve their parameters.
