Curving Performance Analysis of a Freight Train Transporting 50-Meter-long Rail Using Multibody Dynamics Simulation

Long rails are normally used in highspeed railways to minimize the number of rail joints and dynamic impact force that follows. However, transporting long using a freight train requires multiple wagons for each section, presenting potential safety loading gauge issues, especially when going through curves. Thus, assessment needs be done prior actual transport. Computational simulation can preliminary assessment. Finite element analysis incorporate flexibility into but significant manpower computer power perform. In this study, an alternative method model multibody approach is presented. The sectioned rigid bodies along their length interconnected rotational joints. stiffness coefficient defined as function rail’s physical properties. This modelling technique results simplified retains original elastic Simulations constructed hauled were compared on-track test measurements same configuration. comparison generally showed good agreement, showing technique’s ability accuracy simulate case.
