Recent updates and revisions. Derailment conditions can be simulated with the input of measured track geometry data, actual wheel and rail profile shapes. The specifications of actual vehicle suspension conditions and the presence of unusual conditions and external forces acting on the car can be input to the NUCARS model to permit the user to explore the wheel/rail interaction forces and other dynamic conditions that lead to derailment. Wheel and Rail Profile Design Optimization. NUCARS wheel/rail inter...
