Abstract
An impulser for percussively loading a structure to generate stress waves in the structure by driving a hammer into impact relation with the structure and generating an electrical signal in timed relation to the impact. The impulser may embody means, such as suction cups, for firmly attaching the impulser to the structure and an anvil which is interposed between the hammer and structure and spring loaded against the structure for transmitting the hammer impact to the structure without damaging the structure.
