Title:
BALANCED FALLING MECHANISM AND GRAVIMETER
Document Type and Number:
WIPO Patent Application WO/2021/244426
Kind Code:
A1
Abstract:
A balanced falling mechanism and a gravimeter. A driving apparatus can drive an adjusting member to move in the vertical direction. When a bearing member (330) and a mass member to be measured (340) move in the vertical direction, and said mass member (340) is separated from the bearing member (330) so that said mass member (340) does a free fall motion, the overall gravimeter can be analyzed by means of the theorem of momentum of a particle system; with maintaining the overall center of mass of the gravimeter unchanged as a control target, the state of the adjusting member (430) moving in the vertical direction is obtained, and the overall center of mass of the gravimeter can further be maintained unchanged by controlling the movement state of the adjusting member (430), thereby eliminating the influence of recoil vibration on the measurement process.
