Improving the conditions for securing intermodal units against transverse vibrations and longitudinal displacements along the route

This article focuses on the mathematical modeling of counter-rail transportation processes, examining the parameters of forces acting on vehicles transported on railway platforms. It aims to improve the mathematical model of fastening conditions in counter-rail transportation, considering various factors, and to develop a device for securing vehicles to railway platforms. The shear strength of the fastening device must not be less than the calculated shear forces. By determining the values of individual forces acting on each fastening device, the correct number of fastening points can be established. In addition to the continuous forces acting on the load, centrifugal force during curves and turns is also considered when calculating the fastening devices. The total forces experienced by the fastening devices due to the combined effects of “shear” and “holding” forces on the load placed on the platform are determined. Considering that the longitudinal displacement and transverse vibration of vehicles depend on their design, surface characteristics, speed, radius of curvature, and coefficient of friction, the values of individual forces acting on each of the fasteners were calculated.
