Apparatus for measuring the characteristics of a body mass and its application to the measurement of the characteristics of a satellite a dry.

摘要

Measuring apparatus for the determination of the mass of the position of the center of gravity and of the moments of inertia of a body is held in a predetermined constant orientation of the kind comprising, carried by a base, a plate for receiving this body is mounted to pivot with respect to an axis normal to the platform substantially vertically on either side of a stable angular equilibrium position towards which the plate is returned elastically by return means, this plate, and this base being provided with a detector of the angular position of the plate with respect to the base and of locking members of the plate with respect to the base and of locking members of the plate on the base, characterized in that this base is - same carried by a movable structure carried by a base and mounted to oscillate with respect to a horizontal axis which intersects the vertical axis at an adjustable height, on either side of a stable angular equilibrium position, in which the normal axis of the plate is vertical and to which the fixed structure is returned elastically by second return means, this base and the mobile structure being provided with a system for detecting the angular position of the mobile structure with respect to the base, on the locking members of the fixed structure with respect to the base in the position of stable equilibrium and members for adjusting the height of the horizontal axis of oscillation, this apparatus is also provided with means for positioning and locking of the body with respect to the mobile structure of a plurality of angular positions.
