Розрахунок рейки як балки на пружних опорах під дією рухомого навантаження

Abstract

To determine the reduced vertical stiffness of the threads under the rail wheel crew reviewed the calculation of the rail as a beam on elastic supports individual using the equations of five points. The resulting system of equations is solved in matrix form using the equations Cramer. Accounting for random characteristics of the rigidity of individual towers, the distance between the axes of sleepers, movement between the rails and sleepers made using the method of statistical tests. The proposed method of determining the reduced stiffness of rail thread can get its variable values for each wheel of a moving crew at any time.
