ABSTRACT:
The invention is in the field of dynamometer testing of aircraft wheel and brake assemblies and, more particularly, relates to the simulation of brake and landing gear vibration dynamics on a dynamometer. The test apparatus and method according to the invention employ a pitch beam that simulates bogie pitch motion, and a walk beam that simulates landing gear walk.
