Abstract
The present invention provides systems and methods that can provide a high g-force to a test specimen. An exemplary system of the present invention includes a beam, rigidly fixed at one or both ends, on which a test specimen can be mounted. A loading device is preferably provided that can load the beam by using a ceramic column positioned between the beam and the loading device. A flywheel that has a cutter that can be deployed on command while the flywheel is rotating to fracture the ceramic column is also provided. The present invention also provides systems and methods for controllably damping the oscillation of a loaded beam at some point after the load on the beam is released to produce a high g-force event. For example, a damping device of the present invention may be engaged after the completion of the high g-force event. Such damping can prevent subsequent ringing or oscillation of the beam without affecting the magnitude of the high g-force event.
