Abstract: Gear transmission system has also become an indispensable component in the equipment manufacturing industry. With increasingly complex service environment of equipment in ocean engineering, aerospace, transportation, energy and other fields, extreme working conditions with high speed, heavy load, and drastic disturbances occur more frequently than before, resulting in a surge in vibration and noise in the gear transmission system, and threatening the overall reliability, comfort and concealment. Therefore, the dynamic performance of gear transmission system has become the key to promoting the operating performance of the system and the entire machine, and there is an urgent need to design the gear transmission system according to the dynamic performance. Based on an extensive survey of domestic and foreign research results, the existing dynamic performance analysis methods of gear transmission system are summarized, and a number of internal and external excitation factors that affect the dynamic performance are sorted out. Especially, the impact of multi-source excitations and uncertainty on the dynamic performance is emphasized. The optimization methods towards the dynamic performance with single/multiple objective(s) and those considering uncertainties and robustness are also summarized. The applications of modern dynamic performance design methods are also introduced from the aspects of marine ships, railway, wind turbine, robots, aerospace, etc. This work is not only beneficial for constructing a comprehensive and intelligent system for dynamic performance design, but also helpful for improving the vibration, noise and other synthetical characteristics of gear transmission system.

Key words: gear transmission system, gear dynamics, uncertainty analysis, optimization design
