| 介绍了加速度计稳定性的测量装置及方法，根据环境因素可以对稳定性测试的影响，因此对加速度计的工作温度、基础水平倾角的影响进行了分析。通过研究加速度计温度误差模型，确定了建模方法。在稳定性试验中，使用高精度铂热电阻测量加速度计的工作温度，对加速度计的模型方程系数和输出进行温度补偿；使用地震前兆倾斜仪监测基础水平倾角变化，对加速度计零位输出进行补偿。 |
| 英文摘要: |
| This paper introduces the measuring device and method for stability testing of accelerometers, and studies and establishes the temperature error model of accelerometers by analyzing the effects of environment factors, including operating temperature of the accelerometer and foundation horizontal inclination, on stability test of accelerometers. In the stability test, the high precision platinum thermal resistance is used to measure the operating temperature, and the earthquake precursory inclinometer is used to monitor foundation horizontal inclination. The measured operating temperature compensates for the coefficients of the model equation and outputs of the accelerometer. The measured foundation horizontal inclination compensates the zero output of the accelerometer. |
