Abstract: Methods and systems are provided for determining frequencies associated with tire crown bending. The system includes a vibration generating device configured to excite vibrations through a tire. The system further includes a vibration sensing arrangement configured to sense vibrations at a plurality of sensing points on the tire. A computer is in communication with the vibration sensing arrangement and configured to determine a first frequency associated with bending of the crown of the tire based at least partially on phase differences between the sensed vibrations at the plurality of points on the tire.

Abstract: Methods and apparatus are provided for attenuating vibrations in the header of a vehicle to reduce acoustic noise. The apparatus includes a fluid damper configured to be coupled to a header of a vehicle and an accelerometer for sensing vibrations in the header and providing a signal to adjust the fluid damper thereby attenuating the vibrations. A method is provided which includes receiving a signal indicating a vibration in a header of a vehicle and adjusting a fluid damper coupled to the header in response to the signal thereby attenuating the vibration.
