Dynamic Counteracting Method for the Centrifugal Force Acting on the Shaker of Vibration Table in the Centrifugal Field

In the experiment system of the synthesis environment of vibration and centrifuge, the centrifugal force will act on the shaker of vibration table and force it deviating from the original operation position, which will effect on the normal operation of the shaker. We proposed a dynamic counteracting method by means of the pneumatic spring to counteract on the centrifugal force. In order to realize this method in the experiment system, we designed and established a pneumatic servo system with the computer control. The test results show that the servo system has an excellent performance and can be used in the automatic counteracting system.
