斜对称轴结构的差分电容式地震计研制
|
摘要
基于斜对称轴的设计结构,提出了一种采用差分电容式位移型换能器的设计方法。利用加速度计电路耦合积分电路的方法实现差容式力平衡地震计的研制。实验结果表明:地震计在0.01—25HZ的频率范围内具有平坦的幅频特性曲线;线性度小于1%;动态范围大于120dB。
Based on the structure of tilting axis of symmetry,a method for the differential capacitance transducer is introduced.Using accelerator coupling integrating circuit,the force-balanced differential capacitance seismometer is designed.The experimental results indicate that the seismometer has the characteristics of flat frequency response between 0.01 and 25 Hz(within 3 dB),with linearity lower than 1 % and dynamic range over 120 dB.
