Vibration Isolation through Magnetic Suspension, Application to Ballistic Gravimeter

The vibration isolation properties of the offered equipments with the moved ferromagnetic core and with double magnetic suspension are considered. The improvement of these properties in comparison with ones of the known magnetic suspension equipments is shown. The magnetic suspension for isolation from vibration in the ballistic gravimeter is presented. The constraction, schemes and parameters of this equipment are presented. The results of the test show that root mean square deviation of the mesurement of the acceleration of the gravity is decreased 2.5 - 7 times with engaged maonetic suspension vibration damper than without one.
