WHEELCLIMB DERAILMENT CRITERIA UNDER STEADY ROLLING AND DYNAMIC LOADING CONDITIONS

Criteria for predicting wheelclimb derailment under steady rolling conditions are developed analytically and verified experimentally using a one-fifth scale model wheelset on tangent track. Criteria based on wheel and axle loads are compared, including the effect of applied roll moments. Derailment limit under dynamic wheelclimb are established using a nonlinear simulation model.
