Ostapchyk A. Ballistic gravimeter with two-dimensional video

The dissertation offers and researches a new scheme of BLG measuring sys-tem. A specified model of a new BLG is made. The analysis of BLG main errors is performed. The algorithm is developed, a computer study of BLG behaviour. The BLG behaviour for the most unfavorable resonance modes and for different correla-tions of revolting factors values of and ballistic gravimeter own parameters. The conclusions arrived at analytical research of BLG behaviour are confirmed: the most dangerous from the point of resonance origin is the case of coincidence of indignations frequency with BLG natural vibration frequency. Experimental researches are performed. The automated system with new BLG is created and experiments are conducted with it. The equipment of this system is presented. The main theoretical conclusions are practically confirmed. The achived results are proved experimentally and by computer mathematical modeling. Descriptions of digital facilities of video formation are analyzed. The paper provides additional compensation of errors of measuring the abso-lute value ADG based on complexing two systems at measuring the way and time of trial body free motion. The results of measuring the way and time of trial body free motion, and also the absolute value ADG recived from the first and, addition-ally introduced, second systems of measuring these parameters in a ballistic gra-vimeter are averaged in a digital computer. This a new ballistic gravimeter provides the substantial increase of accuracy of the results of measuring absolute ADG. Key words: ballistic gravimeter, the acceleration of gravity.
