ABSTRACT:
A fatigue test system includes a frame having top, intermediate and bottom supports each operatively interconnected by at least one extension, and the intermediate support being disposed between the top and bottom supports. The fatigue test system further includes a driving mechanism connectable to one of the supports to drive the support substantially along a longitudinal axis of the extension for fatigue testing at least one spring disposed between the top and intermediate supports, and at least one further spring disposed between the intermediate and bottom supports. In an alternative embodiment, the fatigue test system includes a frame including top and bottom supports each interconnected by an extension, and a driving mechanism disposed between the top and bottom supports for driving springs against the top and bottom supports, each spring being fatigue tested by being driven along a longitudinal axis of the extension or a central axis of the spring.
