A Wedge Fastening Strength Recognition System for Safety Diagnosis of Large-Capacity Generators and Propulsion Systems For Navy Vessels

This study was designed to safety management methods for military gas turbine generators. The weakening of the generator wedge's fastening strength due to long-term continuous operation is diagnosed through the acceleration signal generated when hitting, and notifies an user whether the generator wedge needs to be replaced. A uniform blow is made with a mechanical device, and the acceleration signal generated during the blow is used to classify the fastening strength into three states through a muti-Iayer perceptron (MLP) [1]. Through this, it is possible to prevent accidents due to generator failure.
