Experimental and Theoretical Analysis on Independent Rear Suspension and Body Structure to Reduce Interior Noise 770177
A theoretical and experimental vibration analysis was carried out on the vehicle equipped with independent rear suspension in order to reduce the interior noise. As the results it is confirmed that the following items have the great effects on the transmission of exciting force; namely:
Dynamic stiffness of mounting insulator
Rigidity of suspension-member
Rigidity of body structure where suspension is mounted
These results were applied to the actual new type of vehicle and its interior noise was measured and three-four dB (A) of noise reduction was obtained.
