力平衡加速度计在线动态测试方法的实验研究

Experimental research for on-line dynamic test of force-balance-accelerometer

为了提高强震观测系统中力平衡加速度计动态测试的效率并降低成本,本文提出了利用力平衡加速度计内的自标定机构进行在线动态测试的方法。通过对比力平衡加速度计的绝对测试和在线测试实验结果,证明自标定机构可以代替超低频标准振动台来进行力平衡加速度计的动态测试。

In order to raise the efficiency of the dynamic test of foree-balance-accelerometer （FBA） in a strong ground motion measurement system and to reduce its cost, a new on-line dynamic test method is presented by using the self-calibrating mechanism （SCM） in FBA in this paper. According to the experimental results of absolute test and on-line test, the ultra low frequency vibration table is substituted with the SCM for FBA dynamic test.
