　　In order to reduce the gear whine noise of a DCT oil pump,a model is established based on loaded tooth contact analysis method,and the gear transmission error and acceleration of the DCT housing are calculated in different torques.The influences of gear macro-geometry and assembled errors on housing acceleration are researched,and the primary factors influencing gear whine noise have been found.Finally gear design is refined,and the oil pump gear noise is dissipated in vehicle NVH test.
