Virtual-Array Operational Modal Analysis of Rolling Tires Using a Single Tire Cavity Accelerometer

arXiv:2606.10437v1 Announce Type: new Abstract: The dynamics of rolling tires significantly influence the low-frequency (0-500 Hz) structure-borne noise within vehicles. Accurately characterizing these dynamics under realistic operating conditions remains challenging. Current state-of-the-art methods, primarily relying on Laser Doppler Vibrometers (LDV), are complex to implement, time-intensive, and generally limited to smooth tires in laboratory environments due to issues with speckle...
