Mobile bipendulum impact test machine

Abstract:

A bipendulum impact test machine for imparting impact damage includes a frame of beams where a weighted sled swings from a pair of links extending from a carriage. The carriage and sled are vertically adjustable along a set of vertical shafts of the frame. The sled is permanently horizontally oriented and parallel with the carriage. Interchangeable impact tips are removably and adjustably engaged with the sled. The impact tips have a variety of shapes in order to simulate different impact scenarios. The device is mobile and capable of imparting impact damage to large aircraft parts even in an installed condition.
