Abstract The flexibility of the casing plays an important role in dynamic response gas turbine rotor. effect support parameters on stiffness supporting components must be considered. While finite element method analyses remain valuable, their time-intensive nature, particularly model definition, necessitates search for more time-efficient methods. Motivated by need fast, manageable solutions with repeatable configurations within defined design parameters, this paper introduces a novel...
Health indicators (HIs) are greatly significant in sustaining the stable operation of machines and guiding implementation predictable maintenance. Traditional HIs such as kurtosis, negentropy, Gini index manifest some concessions certain scenarios. In this study, we propose a new geometric partition L-Kurtosis (GLK) indicator for bearing condition monitoring leveraging its splendid fault characterization, it is proved to be advantageous perceiving incipient occurrence outlining sufficiently...
Recent advancements in applications of deep neural network for bearing fault diagnosis under variable operating conditions have shown promising outcomes. However, these approaches are limited practical due to the complexity networks, which require substantial computational resources, thereby hindering advancement automated diagnostic tools. To overcome limitations, this study introduces a new framework that incorporates tri-channel preprocessing module multidimensional feature extraction,...
