Two-Dimensional Finite Element Modeling of Ultrasonic Time-Of-Flight Diffraction (TOFD) Technique

These approaches are useful in case of bearing investigation during its life service and could help the user in implementing predictive maintenance. On the other hand, visual inspection is commonly used for periodic inspection and maintenance. Although, this approach could help in failure analysis and qualitative inspection of roller bearings, however, there isn’t any generalized method which could monitor the damage through quantification of surface damage level. There are different approaches for surface parameters quantification.. In this paper bearing surface geometry is investigated through Ultrasonic Spectroscopy. Three types of spherical bearings with healthy, somewhat faulty, and absolutely faulty status are investigated. Practical aspects of this approach are discussed herein and comments about future works are outlined.
