Machine learning-based method for analyzing stress distribution in a ship.

ABSTRACT: Ship structural health monitoring (SHM) systems are essential for ensuring operational safety. Monitoring stress distribution is a critical function of such systems. Analysis of stress data collected by pressure sensors can enhance understanding of SHM performance and facilitate the prevention of structural failures. In this study, we propose a machine learning-based computational method to analyze the stress distribution of a crane ship. The method first employed extreme gradient boosting (XGBoost) to evaluate relationships among stress data from multiple pressure sensors, and then used multilayer perceptron (MLP) to construct regression models. For each pressure sensor, an optimal MLP regression model was established to infer its stress values from those of related sensors. These models
