Abstract
High-precision mechanical transmission systems play a crucial role in modern industry and are widely applied in fields such as precision manufacturing and aerospace engineering. With the increasing demands on transmission accuracy driven by technological advancements, traditional design methods have become inadequate to meet these requirements. This study aims to explore a novel design and optimization approach for high-precision mechanical transmission systems. By incorporating advanced finite element analysis and multibody dynamics simulation techniques, an accurate mathematical model was established based on actual operating conditions, enabling precise prediction of transmission errors. An innovative parameter optimization method based on intelligent algorithms was proposed, effectively addressing the inefficiency issues associated with conventional optimization methods. Experimental results demonstrate that the system maintains stable high-precision transmission performance under various load conditions, with the maximum transmission error reduced by approximately 30% compared to traditional systems. Furthermore, structural optimization of key components significantly enhances the system's stiffness and anti-vibration performance. This research not only provides new insights into the design of high-precision mechanical transmission systems but also lays a solid foundation for theoretical studies and technical applications in related fields, showcasing significant academic value and broad application prospects.
