离心场中的振动台动圈离心力动态补偿方法

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

在振动离心复合环境试验系统中,当振动台动圈受离心力影响偏离原来的平衡工作位置时,将会影响振动台的正常工作。为了消除这种影响,本文提出了一种使用空气弹簧来抵消离心力影响的动态补偿方法。为了实现这种方法,设计了相应的气压伺服系统,进行了具有计算机控制的气压伺服系统原理性仿真实验。实验结果表明这种气压伺服系统具有良好的跟踪控制性能,可以满足动态补偿离心力对振动台动圈影响的要求。

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.
