Abstract
A system for inducing shock may include a first slap plate attached to a shaker armature of a shaker table system to impart a shock to any object being tested by the system. The shock is amplifiable by use of the first slap plate compared to the object being coupled to the shaker armature without the first slap plate. The system may also include a specific attachment arrangement for attaching the first slap plate to the shaker armature. The specific attachment arrangement and a configuration of the first slap plate may be selected to control a level of shock imparted to the object being tested.
Claims23
A system for inducing shock, comprising:
- a first slap plate attached to a shaker armature of a shaker table system to impart a shock to any object being tested by the system, wherein the shock is amplifiable by use of the first slap plate compared to the object being coupled to the shaker armature without the first slap plate;
- and
- a specific attachment arrangement for attaching the first slap plate to the shaker armature, wherein the specific attachment arrangement and a configuration of the first slap plate are selected to control a level of shock imparted to the object being tested, wherein the specific attachment arrangement selected to control a level of shock imparted to the object being tested comprises:
- a plurality of fasteners attaching the first slap plate to the shaker armature, wherein each of the plurality of fasteners extend through the slap plate and are received in a threaded opening formed in the shaker armature;
- and
- a predetermined number of spacers associated with each fastener to provide a selected spacing between the first slap plate and the shaker armature.

1 more element
A fixture for inducing shock forces to a test specimen, comprising:
- a slap plate attached to a shaker armature of a shaker table system by a selected number and location of fasteners on the slap plate to allow the slap plate to strike against the shaker armature when exposed to shaker induced shock;
- an attachment arrangement for attaching the slap plate to the shaker armature, wherein the attachment arrangement and a configuration of the slap plate are selected to control a level of shock imparted to the test specimen, wherein the attachment arrangement to control a level of shock imparted to the test specimen comprises:
- a plurality of fasteners attaching the slap plate to the shaker armature, wherein each of the plurality of fasteners extend through the slap plate and are received in a threaded opening formed in the shaker armature, and
- a predetermined number of spacers associated with each fastener to provide a selected spacing between the slap plate and the shaker armature;
- and
- a host platform attached to the slap plate by a selected number and location of fasteners, wherein the host platform is adapted to hold the test specimen and transfer shock to test specimen from the shaker armature and slap plate.
3 more elements
A method for inducing shock, comprising:
- attaching a slap plate to a shaker armature of a shaker table system to impart a shock to any object being tested by the system;
- and
- using a specific attachment arrangement for attaching the slap plate to the shaker armature to control a level of shock imparted to any object being tested;
- and
- controlling the level of shock imparted to any object being tested wherein controlling the level of shock imparted comprises:
- attaching the slap plate to the shaker armature with a plurality of fasteners, wherein each of the plurality of fasteners extend through the slap plate and are received in a threaded opening formed in the shaker armature, and
