Abstract
High-speed precision mechanical transmission system plays a vital role in modern industry, and its stability directly affects the equipment performance and production efficiency. In view of the shortcomings of dynamic characteristic analysis of transmission system under complex working conditions, this study aims to explore the key factors affecting the stability of high-speed precision mechanical transmission system, and put forward effective analysis methods and optimization strategies. By combining nonlinear dynamics theory and finite element simulation technique, a mathematical model including gear engagement, bearing support and vibration is constructed to accurately describe the dynamic characteristics of the system. The study further introduces frequency domain analysis and chaos detection methods, and reveals the influence of different operating parameters on system stability. The results show that the gear microgeometry error, lubrication state and external excitation frequency are the main causes of system instability.
