In order to analyze the influence factors of vehicle interior gear whining order noise from the mechanism, a time-domain hybrid analysis model of gear whining is built in this paper. The acceleration of the mount’s active side and near-field noise result is acquired mainly based on the time-domain dynamic multibody model. Then the result data is used as input and loaded into the vehicle time-domain transmission path mathematical model, so as to calculate the vehicle interior gear whining order noise through virtual analysis. Compared with the real vehicle test results, the frequency error of the vehicle interior gear whining order noise calculated by this method does not exceed 6%, and the amplitude error does not exceeded 12%. On this basis, the method is applied to analyze the sensitivity of the factors affecting the gear whining on a certain vehicle type. It is found that the tooth shape modification and high-frequency vibration isolation of the mount etc. are the main causes of the vehicle interior gear whining. After the verification of the real vehicle test, the good accuracy of this modeling method is furtherly proved, which provides a powerful technical reference for the industry to solve this problem.
