压电加速度计重力场标定台是利用重力场的原理而制成的。在低频和超低频范围内,它不仅可标定压电加速度计和其他类型加速度计的动态特性,而且还可以标定力传感器的动态特性,包括轴向灵敏度、横向灵敏度和频响。此外,它还可作为研究成套测振仪器的低频和超低频特性的计量手段。本文介绍了它的原理、构造、特性和标定方法。
Piezoelectric accelerometer gravitational field calibration station is made using the principle of gravity field. In the low and ultra-low frequency range, it not only calibrates the dynamic characteristics of piezoelectric accelerometers and other types of accelerometers, but also calibrates the dynamics of force sensors, including axial sensitivity, lateral sensitivity and frequency response. In addition, it can also be used as a means to study the low-frequency and ultra-low frequency characteristics of a complete vibrometer. This article describes its principles, construction, characteristics and calibration methods.
