This paper is based the coupling of finite element method and multi-body dynamics method, the AVL-EXCITE Power Unit software is used to build a 14s heavy-duty transmission vibration simulation model, and with the transmission vibration test on the standard, the simulation results reproduce the 14s whine noise. Based on the gear repair theory, the KISSOFT software is used to modify the gear surface, and then the whine noise of the transmission is optimized. On this basis, a simulation method of transmission whine noise optimization is formed . The results show that the micromanipulation of gears can reduce the transmission error and improve the effect of whine noise.
