Abstract: 　　Vibration of gears on the actual working conditions is simulated by the state-space method. The dynamics is modeled as a non-linear, time-correlated, and stationary-stochastic system. The random component of gear transmission error is simulated by a second-order Markov process used as a shaping filter. By means of the simulation software and dynamic gear tests, the main factors to affect gear vibration such as composite error, random error, speed, loud and gear parameters etc are investigated.
