摘 要：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 *** acceleration of the mount s active side and near-field noise result is acquired mainly based on the time-domain dynamic multibody *** the result data is used as input and loaded into the vehicle timedomain transmission path mathematical model,so as to calculate the vehicle interior gear whining order noise through virtual *** 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 *** is found that the tooth shape modification and high-frequency vibration isolation of the mount *** the main causes of the vehicle interior gear *** 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.
