针对温度、振动、湿度等因素会影响石英挠性加速度计的参数漂移这一问题，对石英挠性加速度计在贮存条件下的稳定性进行了研究。首先在贮存条件下采集石英挠性加速度计的零偏数据，分析数据特点及规律，然后建立时间序列数学模型，最后对模型进行进行仿真。将贮存条件下的真实数据和预测数据进行对比，对比结果表明建模是有效的，建模所得数据的相对误差在允许误差范围内，证明了建模的适用性。预测数据反映了在贮存条件下零偏数据随周围环境变化的规律，为研究石英挠性加速度计在贮存条件下的稳定性提供了理论参考。

Aiming at the problem that the parameter drift of quart flexible accelerometer will be influenced by the factors, i. e. , temperature , vibration and humidity, the stability of quartz flexible accelerometer under storage condition is studied. Firstly, the zero offset data of quartz flexible accelerometer under storage condition are collected, and the characteristics and rules of data are analyzed; then the time series mathematical model is established;finally the simulation of the model is conducted. The real data and the predicted data under storage condition are compared, the result of comparison shows that the modeling is effective;the relative errors of data obtained by modeling are within the range of tolerance, thus the applicability of modeling is verified. The predicted data reflect the regular pattern of zero offset following the changes of surrounding environment under storage condition;this provides theoretical reference for researching the stability of quartz flexible accelerometer under storage condition.
