Abstract

Purpose: Accounting for dynamic nature of the effects of forces from a rolling stock on a bridge taking into account passway roughness in high-speed traffic conditions in the calculation model “Moving Dynamic Forces on the Beam”. Methods: Derivation of the differential equations of the proposed system by analytical method. Results: Equations for determining the magnitude of the inertia forces X1 and X2 of a rolling stock sprung part. Practical importance: Obtaining the updated picture of bridge structure dynamic operation in high-speed traffic conditions by the way of change of “Moving Forces on the Beam” calculation model to “Moving Dynamic Forces on the Beam” model.
