Abstract: Gear system is widely used and often act an important role in essential equipment. Aiming at the problem that its vibration problem at high rotation speed, interior complex structure and various nonlinear factors bring huge difficulty to its kinetic analysis and design, to summarize its kinetic study is of theoretical significance. Based on the analysis and summary on gear transmission′s dynamics research achievements, the basic framework of gear system′s dynamics theory was described, the results indicate that the content includes system input, system model and system output. According to the research methods of nonlinear systems, the study on gear system′s nonlinear dynamics and the research status of whole multi-stage gear system during past ten years were summarized, especially the typical automotive transmission, and the focus of future research was shown. Finally, the possible research focus and directions in dynamic behavior, vibration and noise, fault diagnosis and reliability of the transmission were put forward.
