ELECTRO-SEIS Long Stroke Exciter
Ball Bearing

ELECTRO-SEIS®

The ELECTRO-SEIS® is a force generator specifically designed to be used alone or in arrays for studying dynamic response characteristics of structures such as automobiles, aircraft, bridges, floors, missiles, piping systems, spacecraft, towers, etc.

TYPICAL APPLICATIONS

  • Modal Testing - Excitation source used for the determination of a structure's damped natural frequencies, damping factors and mode shapes.
  • Compliance & Fragility Testing - Used in dynamics laboratories to determine compliance with various commercial and military specifications.
  • Seismic Testing - Low frequency excitation source to assess survivability and performance during simulated seismic events.
  • Transducer Calibration - Used both in laboratory and field environments for the amplitude and frequency calibration of vibration sensors.
  • Structural Transmission Testing - Field and laboratory excitation source used for the determination of structureborne noise paths, transmissibility's and stress. distributions
