Abstract
A rolling search unit for ultrasonic inspection of railroad rails employs a wheel assembly including a fluid-filled tire that rolls along a rail with ultrasonic transducers that propagate ultrasonic beams through the fluid and tire into an underlying rail during an inspection operation. The beams reflected from defects in the rail return to the transducers and are detected and analyzed for subsequent care. The wheel assembly also includes an anti-rotation baffle to reduce rotation of the fluid with the tire and a pressure regulator for controlling the pressure of the fluid within the tire at various speeds.
