The Vibration Test Unit (VTU) is designed to vibrate a railcar to simulate the action of track/train dynamics using a hydraulic shaker system. Studies of suspension characteristics, rock and roll tendencies of rail vehicles, component and vehicle natural frequencies, ride comfort, lading responses, and simulation of full scale vehicle inputs at each wheel/rail interface and lateral inputs along each axle line at the rail/wheel interface. The VTU uses a dual minicomputer system for signal generation, data acquisition, and limit checking.
