ABSTRACT:
An electrodynamic force generator or vibrator employing plural ring permanent magnets and a round magnetic structure of the center gap type that is split on a horizontal plane passing through the center and a support and guidance system for supporting the vibratory table and coil consisting of a plurality of horizontal damped cantilever springs joined to "C" shaped damped compensating springs. Typically, a round drive coil of plural turns surrounds a central core or pole of the magnetic structure and is influenced by flux on all sides. Shorted turn coils surround the drive coil and are stationary upon the outer pole to provide reduction of inductance. The drive coil is attached to a table structure which is supported and guided in the magnet structure.
The support and guidance system for the table and drive coil of the force generator consists of three or more sets of horizontal damped cantilever springs joined to a like number of "C" shaped essentially vertical damped springs which compensate for the shortening effect of the horizontal spring during long excursion of the table of the force generator.
