低频振动标准套组的研制

Development of the Low-frequency Vibration Standard Combination

介绍了石英挠性伺服加速度计和研制的低频振动适调器组成了低频振动标准套组，在0．1～100Hz的振动频率范围内，能够把微弱、噪声较重的加速度信号，调理成信噪比较强、较稳定的信号。为低频振动加速度的量值复现、基标准装置的稳定性考核和量值溯源等提供了有力的保证，此标准套组还可广泛应用于其它低频振动测量领域。

A low-frequency vibration standard combination is composed of the quartz-flexible servo accelerometers and a self-developed conditioning amplifier. It can adjust the very weak and heavy noise aceelerometer signal to a strong and stable signal to noise ratio. It provides a powerful guarantee for low frequency vibration value replicable and vibration value stability assessment and vibration value traceability of the vibration standard devices. The low frequency vibration standard combination can applied in many other low frequency vibration field.
