Test stand used in drop weight testing equipment, has actuator that prevents renewed contact of mass with impact surface, according to first contact of falling mass with impact surface and return of falling mass

摘要

The test stand (100) has actuator (4) has impact mass arranged through the impact surface, such that they are in free fall state on the impact surface. The actuator prevents a renewed contact of mass with impact surface, according to first contact of the falling mass with the impact surface and return of the falling mass. An independent claim is included for method of characterizing dynamic component stress and/or strain component by specific induction of impact event.
