总结了常见的平台调平方法,对基于空气弹簧支撑的平台系统自动调平及提高调平精度的方法进行了研究.空气弹簧平台系统固有频率低、阻尼小的特点,采用简单的高度控制阀控制的三点支撑机械调平机构即可实现平台的自动凋平,其调平度在几百角秒.采用动态跟踪调平法,对平台俯仰和偏摆两个方向的水平度进行控制,可以提高平台系统的调平精度.实验结果表明,平台两个方向水平度保持在±15"内.

The leveling method of common platform was summerized, and the platform system based on the air spring supporting, the auto-leveling method and the method about improving the accuracy of auto leveling were studied. The natural frequency of the air spring platform system is low, and damp is small, so with a simple setup made by leveling valve and three-point support mechanical leveling device it can achieve the automatic leveling range within a few hundred arc-sec.. And then using the method of dynamic tracking to control both directions in pitch and deflection of the platform it can obtain better level accuracy. The results of the experiment show that level degrees of two directions are within ±15 arc-second.
