Performance

Performance is given in the form of graphs which present the envelopes of maximum force and velocity delivered to a resonant structure as functions of the 
resonance frequency of the structure.

Another application is the excitation for sensor calibration. Acceleration envelopes of the APS 400 ELECTROSEIS® shaker with various mass loads are shown in this graph for the 445 N rating.
