It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The article presents a numerical and analytical method for studying the bending-longitudinal vibrations of the load-bearing frame of the locomotive frame of a complex configuration in the form of an elastic rod of variable cross-section with variable mass, bending and longitudinal stiffness, based on methods: piecemeal linear approximation, iterations and the Boundary Element Technology. Numerical studies are performed in C # and in MATHCAD 15.
