VALIDATION OF AN ELECTROMAGNETIC INDUCTION SIMULATION FOR DEFECTS DETECTION: A QUASI-STATIC MODEL FOR AN AUTOMATED INSPECTION SYSTEM
Published: 30 Apr 2016
Abstract: The herein presented paper describes the simulation carried out in the scope of defects detection through electromagnetic induction and the validation with experimental test. A coupled electromagnetic and thermal model was carried out with the software ANSYS Multhyphysics. Through this method the possibility to detect defects based in electromagnetic induction was assessed. In fact detection occurs due to the induced current concentration on the edges of the defects and thus they can be visible in the resulting induced current patterns as well as on the generated temperatures. In addition a quasi-static model was developed for replicating a system in which the defects tool is moving for a completely automatized inspection. An experimental test was also performed for the validation of this predictive tool, to finally obtain a reliable and consistent model that may be used for future studies. This paper demonstrates the accuracy and match of the results between the simulation model and the physical experiment and thus the availability of the model to optimize the system and required parameters, prior to the physical construction and tests, with the consequent time and economic savings.
