Abstract
A system for characterizing a vehicle tire is provided. The system includes a testing assembly configured to support the vehicle tire. The assembly includes a force-moment transducer configured to gather force information from the vehicle tire in response to a stimulus on the vehicle tire. The system further includes an accelerometer coupled to the vehicle tire and configured to gather vibration information from the vehicle tire in response to the stimulus on the vehicle tire. The system further includes a post-processing system configured to receive the vibration information from the accelerometer and the force information from the force-moment transducer. The post-processing system is further configured to extract resonant frequencies from the vibration information and the force information.
