Abstract
A computer algorithm that uses raytracing to simulate the ultrasonic inspection of a pin with and without scanning will be described. This algorithm allows the users to simulate the location and orientation of a crack, or wear groove, in the pin and model the ultrasonic reflections that will occur during inspection. The procedure is part of a larger effort to improve the reliability and interpretation of ultrasonic inspection results from steel bridge pins. The simulated results are compared with actual scan results obtained using an automated scanning system on a reference pin with slag and crack imperfections.
