一种石英挠性加速度计温度补偿方法

IAs a key component in the field of inertial measurement, the accuracy of quartz flexible accelerometer plays a decisive role in the performance of many application systems. However, fluctuations in ambient temperature can significantly affect the output characteristics of accelerometers, leading to measurement errors and greatly limiting their application in high-precision scenarios. This article focuses on the research of temperature compensation methods for quartz flexible accelerometers, proposing an innovative temperature compensation framework that integrates multi physical field modeling and intelligent algorithms. By comprehensively analyzing the complex thermal structural electrical coupling mechanism inside the accelerometer, an accurate multi physics field model is constructed to deeply reveal the inherent physical laws of temperature affecting the output. At the same time, advanced intelligent algorithms are introduced to optimize the model parameters and achieve efficient compensation for temperature errors. The experimental results show that this method can effectively improve the measurement accuracy of quartz flexible accelerometers over a wide temperature range, significantly reduce temperature drift errors, and has broad application prospects in engineering fields such as aviation, aerospace, weapons, and ships that require strict acceleration measurement accuracy
