Simulation modelling of the load-bearing capacity of composite wooden sleepers taking into account train load

In this article the process of a composite wooden sleeper 3D-model creating is described, taking into account the physical and virtual components of pine wood. A strength analysis of the sleeper was carried out at the assembly stage. A calculation scheme of pressure in composite wooden sleeper due to the impact of rolling stock is proposed. The influence of train load on the connection strength of sleeper components was modelled. As a result of the calculation, it was established that the strength limits were not exceeded, which indicates the ability of a composite wooden sleeper to withstand a load from rolling stock wheels of up to 50 kN without loss of reliability in the connections between the elements
