Diagnosis of induction motor stator faults around rotor slot harmonics using the Matrix Pencil method by Mohamed Kouadria, Zakaria Chedjara, Chun-Lien Su, Mohamed Benbouzid, Josep M. Guerrero, Babul Salam KSM Kader Ibrahim, Hafiz Ahmed

“…Furthermore, to optimize the calculation time of this method, the article suggests focusing the analysis only on the frequency band corresponding to the first rotor slot harmonics. This approach aims to avoid any interference with the frequency signatures of external factors, which are generally present at very low frequencies. …”

Displacement Transmissibility Characteristics of Harmonically Base Excited Damper Isolators with Mixed Viscous Damping by Xiaojuan Sun, Jianrun Zhang

“…In this paper, performance characteristics of single-degree-of-freedom (SDOF) linear-stiffness isolators with mixed and piecewise mixed viscous damping are analytically examined under harmonic base excitation. Based on the first-order harmonic balance method (HBM), both relative and absolute displacement transmissibility expressions with the equivalent linear damping coefficient (ELDC) are given. …”
