Abstract
In the scope of an SEA project for high frequency tire NVH prediction, use is made of the spatial distribution of “modal power” on the entire surface of a tire, at both the modeling and validation stages. This paper focuses on the model development stage and how the modal power is used to determine the size of the SEA subsystems. Two key results are that, because of large damping, the spatial decay of vibration energy is too great and would require a large number of SEA subsystems. This is a confirmation on the limits of SEA in highly damped systems. It is also found that, in the frequency range where SEA would be useful, the tire's vibration response is concentrated around ⅓ of the tire closer to the excitation location. Experimental results are used to draw more insight into high frequency tire NVH behavior. The paper covers theoretical concepts, measurement setup, data processing, and concludes with useful results.
