ROLL DYNAMICS UNIT AND VIBRATION TEST UNIT

The Rail Dynamics Laboratory (RDL) permits evaluation of various car and locomotive designs in a safe, controlled and reproducible laboratory environment with minimal risk to equipment and personnel. RDL houses two test machines, the Vibration Test Unit (VTU) and the Roll Dynamics Unit (RDU), along with necessary data collection, analysis and service facilities. RDU will be capable, through a system of drive motors, fly-wheels and rollers, of simulating relative rail motion under rail vehicles and absorbing power produced by self-propelled units. VTU will subject a stationary rail vehicle to controlled vertical and lateral vibration inputs at the wheel/rail interfaces through servo-controlled actuators. Physical capabilities of the subsystems of the laboratory are given. Facilities are available for government- and industry-sponsored research programs.
