Seismic Testing

Eccentric Mass Vibrator Controller

FOVDAR is a PC-based controller for performing forced vibration tests using an eccentric mass vibrator.

• Allows the user to define the desired sine sweep range of a test.
• Allows the user to enter location information and calibration factors for up to 200 channels of response sensor.
• Manage the drive frequency profile.
• Acquires, processes and displays up to 200 channels of sensor data.
• Displays frequency response plots in reference the force signal.
• Provides for plotting, archiving, and exporting of all data as acceleration, velocity, or displacement. These can also be normalized to unity force.
