DYNAMIC ANALYSIS OF TRAIN DERAILMENTS

An analytical simulation has been developed to determine the influence of various parameters on derailment severity. In this theoretical analysis the equations of motion for each derailed car are derived in general in the horizontal plane. These are then coupled with a system of constraint equations and the equations of motion for the nonderailed cars. The equations are then solved numerically (by digital computer) in their non-linear forms with the first car derailed as the sole initially assumed condition; and with the ground friction, mating coupler moment and brake retarding force in action accordingly.
