| 2017 | Feedback on the Surveillance 8 challenge: Vibration-based diagnosis of a Safran aircraft engine. J. Antoni, J. Griffaton, H. André, L. Avendaño-Valencia, F. Bonnardot, O. Cardona-Morales, G. Castellanos-Dominguez, A. Daga, Q. Leclère, C. Molina, D. Quezada, A. Partogi.. This paper presents the content and outcomes of the Safran contest organized during the International Conference Surveillance 8, October 2021, 2015, at the Roanne Institute of Technology, France. The contest dealt with the diagnosis of a civil aircraft engine based on vibration data measured in a transient operating mode and provided by Safran. Based on two independent exercises, the contest offered the possibility to benchmark current diagnostic methods on real data supplemented with several challenges. Outcomes of seven competing teams are reported and discussed. The object of the paper is twofold. It first aims at giving a picture of the current state-of-the-art in vibration-based diagnosis of rolling-element bearings in nonstationary operating conditions. Second, it aims at providing the scientific community with a benchmark and some baseline solutions. In this respect, the data used in the contest are made available as supplementary material. https://doi.org/10.1016/j.ymssp.2017.01.037 |
