Resonance test system

摘要

An apparatus ( 10 ) for applying at least one load to a specimen ( 12 ) according to one embodiment of the invention may comprise a mass ( 18 ). An actuator ( 20 ) mounted to the specimen ( 12 ) and operatively associated with the mass ( 18 ) moves the mass ( 18 ) along a linear displacement path ( 22 ) that is perpendicular to a longitudinal axis of the specimen ( 12 ). A control system ( 26 ) operatively associated with the actuator ( 20 ) operates the actuator ( 20 ) to reciprocate the mass ( 18 ) along the linear displacement path ( 22 ) at a reciprocating frequency, the reciprocating frequency being about equal to a resonance frequency of the specimen ( 12 ) in a test configuration.
