Silent paws - the active control of impacts between tyre and road

Start date 01/11/2012
End date The project is closed: 31/12/2013

​The silent walk of animals belonging to the family of felidae, such as cats and tigers is based on the very controlled motion of the paws during impact with the ground. To investigate whether an impact between two bodies can be controlled in a similar efficient way by e.g. utilising smart materials as sensors and actuators is the main objective of the proposed project. The main focus is given to mechanics of the contact between two colliding bodies, exemplified by the tyre/road contact, and the potential of different strategies to actively control this impact rather then to the design of sensors, actuators, or control algorithms. Since the proposed project has a rather general approach, the project outcomes will also help to understand how to control impact forces in processes other than tyre/road interaction.

 

The project is carried out at the Division of Applied Acoustics in research group Vibroacoustics.

Keywords: Active control of impacts and vibrations, tyre-road noise, traffic- and community noise
