Simulation of contact forces of wheel-track interaction due to dynamic movement of MD-۵۲۳ bogie on different track layers

In order to simulate the dynamic behavior of passing a MD-۵۲۳ bogie on infrastructures, it is required to design and define the main features of the bogie including dimensions, suspension subsystem and mechanical detail. Consequently, the wagon and the different types of tracks ought to be defined in mechanical and physical detail including geometry, weight, damping and stiffness.Having the models prepared, the motion simulation is commenced. The results of analyses demonstrate the forces created between the fleet and the rail surface in the contact area. As illustrated by the figures, effects of the contributing factors are considerably resulted
