摘要 

主要介绍了高精度加速度计温度特性和温补方法,从理论上分析了温度对加速度计输出特性影响的机理,通过试验给出了加速度计输出模型温度系数.为了了解加速度计对温度最小变化分辨能力及大温度范围受温度变化影响的趋势,模型温度系数测试进行了在指定温度点最小温度间隔变化输出特性拟合,及大温度范围输出特性拟合.通过测试发现,加速度计输入对准角也随温度发生变化,且有一定的规律,为此在建立加速度计输出温补模型时,加入了输入对准角受温度变化的参变量,这在以往温补模型报道中是没有的.为了验证温补模型的准确性,采用手动升降温的方法进行了实时温度补偿,结果达到了预期目的.

Abstract

In this paper, the authors described the temperature characteristics and the method for temperature compensation of the high precision accelerometer. The principle of the influence of temperature on the output characteristics of accelerometer was analyzed in theory and the temperature coefficients of the accelerometer model were calculated by the tests. In order to find out the resolution of the accelerometer to the temperature minimum change and the influence of a large scale change of the temperature, the model temperature coefficients were tested in small distance change at a specific temperature and large distance change. The results of the tests indicate that the input axis misalignment shifts according to a certain rule when the temperature changes. The parameter of the input axis misalignment shifts with the change of temperature was considered when the temperature compensation model of the accelerometer was built, which had never been considered in the other reports. The veracity of the temperature compensation model was validated according to the tests in which the temperatures were changed manually.
