Abstract: With the deepening of Industry 4.0, intelligent production lines have become the core direction for the transformation and upgrading of manufacturing, and the dynamic performance of mechanical structures, as a key component, directly affects production efficiency and product quality. This study aims to comprehensively analyze the dynamic characteristics of mechanical structures in intelligent production lines and their optimization methods to enhance the stability and adaptability of system operation. By integrating finite element analysis with multibody dynamics simulation techniques, a dynamic performance evaluation model was developed that accounts for complex operating conditions and nonlinear factors. Furthermore, intelligent algorithms were introduced for the optimization design of critical parameters. The results indicate that the proposed model can accurately predict the vibration response and fatigue life of mechanical structures under various load conditions while significantly reducing dynamic errors and energy consumption levels. Additionally, this research innovatively incorporates machine learning technology into the dynamic performance analysis process, enabling real-time monitoring and prediction of the health status of mechanical structures, thus providing crucial support for maintenance decision-making in intelligent production lines. Overall, this study not only deepens the understanding of the dynamic behavior of mechanical structures but also offers theoretical support and technical pathways for the design and optimization of intelligent production lines, demonstrating significant academic value and engineering application potential.
