Vehicle Interior Noise and Vibration Reduction Method Using Transfer Function of Body Structure

A method of vehicle interior noise order analysis was presented to resolve the loud noise problem in a new indigenous vehicle. Sound and vibration properties of the vehicle were tested. The interior noise and vibration acceleration signals at different positions were obtained, and the major sources of noise and vibration were identified. Base on these results, modifications were proposed for different noise sources. The results provide a reference for the optimal design of vehicle motor and transmission system and the internal noise control.

Operational Test

In this study, we propose an analytical method consisting of Operational TPA (OTPA) and Component TPA (CTPA) to predict the vehicle interior noise and vibration without the vehicle operational test in case the noise source such as engine was modified. In the proposed method, the blocked force of the noise source was obtained at a test bench and the vibration at the source attachment point on the vehicle was calculated by CTPA. After then, the response point signal (interior noise / vibration) is estimated from several reference point signals including the calculated vibration by OTPA. For the verification of this method, a simple vehicle model which is composed of four tires and a motor was prepared in addition to a test bench. OTPA was firstly applied to the vehicle model to analyze the contribution from tires and a motor to the body vibration (response point). The blocked force of a modified motor was obtained by CTPA at the test bench and the force was used to predict the response point by OTPA. Finally, the estimated interior vibration was compared with the actual measured response point vibration when the motor was replaced on the vehicle model and the accuracy was verified.
