Abstract

With the development of the wood processing industry toward intelligence, automation, and informatization, Finite Element Analysis(FEA) technology has become increasingly mature in this field. It effectively simulates various aspects, including the properties of wood materials, drying processes, and cutting operations. In material property analysis, FEA technology accurately models the anisotropy and heterogeneity of wood, predicting its mechanical responses under different loading conditions. For drying simulations, it establishes moisture migration models to predict drying stress and reduce defects. In cutting processes, FEA technology analyzes cutting forces, temperature distributions, and surface quality, providing theoretical support for parameter optimization. This review focuses on FEA applications in wood processing, encompassing both solid wood and engineered wood products, simulating and characterizing the drying process of wood products, and modeling cutting operations. It highlights challenges such as model accuracy and algorithm optimization, suggesting that continuous improvements in FEA models and algorithms can further enhance processing efficiency and product quality. Finally, it explores the role of FEA technology in driving innovation and promoting sustainable development in wood processing.
