To the calculation of fastening a solid load under the influence of longitudinal forces

A comparative analysis of the current and updated methods for calculating the fastening of cargo on railway flatcar is presented. It is shown that, in accordance with the existing calculation method, the force in all elastic fasteners has the same value, regardless of the topology of the cargo fastenings. Calculations of forces in elastic fastening elements according to a refined method are presented. The results of a comparative analysis of the calculation results showed that the forces in all wire fastenings, in contrast to the existing method, have different meanings. The main drawback of the refined calculation method is noted – the strength of individual fastening elements is not ensured, since the forces in them are more than twice the permissible values.
