Abstract:
The objective of this paper is to present an Aircraft Landing Systems' (ALS) approach to the solution of the whirl vibration problem of aircraft brakes. The developed method utilizes the concept of asymmetry to break two friction- coupled symmetric modes into two distinct and separated modes. The analytical derivation of the whirl vibration will be first discussed. A method of creating asymmetry will then be presented. Finally, experimental results will be presented that confirm the effectiveness of the technique to reduce aircraft brake whirl vibration.
