Abstract
The invention relates to means of gravimetry for symmetrical method of measurement of absolute values of acceleration of free fall with ballistic gravimeter. Ballistic gravimeter with inductive-dynamical drive for the symmetric method of measurement of acceleration of free fall includes a test body 1 with optical angle reflector 2, vacuum chamber 3, on the upper wall of that one an optical emitter 4 is installed. On the bottom 5 of the vacuum chamber 3 on dampers 6 a massif power plate 7 is installed, there coil 8 with winding 9 is fixed, guide elements as vertical props 10 with circular cross section, and horizontal supports 11 with vertical sections 12. The armature 13 is connected to the power disc 14 in which in proper way three openings 15 are placed, with bearings 16 that surround the vertical props 10. To the bottom of the test body 1 a guide cone 17 is connected axially, the shape of the side walls of that one coincides with the shape of the guide cone-like axial depression 18 of the coil 8. In the armature 13 and the power disc 14 central openings 19 for the guide cone are provided. Vertical props 10 that provide fixed vertical displacement of the armature 13 with power disc 14 and free vertical displacement of the test body 1 are in the upper section connected to the horizontal supports 11 to which elastic dampers 20 are connected. On the bearings 16 that surround the vertical props 11 coaxial holders 22 are installed, the upper reamed section of those interacts with the elastic elements 21 of the holders 23. Electro-mechanical drive of the inductive-dynamical type is arranged as a movable armature 13 that in magnetic way interacts with the fixed winding 9 that is connected to capacitive energy collector by means of two connected in inverse-parallel connection controlled thyristors one of which provides initial repulsion, and the other one – following retardation of the armature with respect to the winding of the coil. The invention provides increase of accuracy of the ballistic gravimeter.
