The results of the assessment of the force effect of heavy and long-component freight trains on the railway track by various measurement methods

Abstract

Objective: to assess the force effect of heavy and long-component freight trains on the railway track by various measurement methods: Schlumpf, influence matrices and the two-section method (PGUPS). Methods: measurements of the assessment of the force effect of heavy and long-component freight trains on the railway track were carried out using the Schlumpf methods, influence matrices and the two-section method (PGUPS). Results: it was found that measurements of vertical dynamic forces by three methods are well correlated with each other, and the Schlumpf method gives overestimated results when measuring horizontal transverse force. Practical importance: the two-section method can be recommended for measuring the force effect of both new and upgraded rolling stock on the railway track, as well as for operated rolling stock in order to identify defects and deviations on the rolling surface of the wheels
