低温压电加速度传感器温度漂移优化设计
Optimization Design for Temperature Drift of Low-temperature Piezoelectric Accelerometers
摘要
Abstract
Low-temperature piezoelectric accelerometers are widely used in vibration and shock testing,fault diagnosis,and monitoring.These critical detection areas are important indicators of a nation's status as a space power.To address the issue of signif-icant sensitivity temperature drift in low-temperature environments,this paper designs an innovative low-temperature piezoelectric accelerometer.This sensor not only exhibits minimal temperature drift in low-temperature environments but also maintains excellent stability in high-temperature conditions.The sensor adopts a compressive structure consisting of a stack of four layers of PZT-5A piezoelectric crystals and one layer of LiNbO3 piezoelectric crystal.Its performance is optimized through ANSYS simulation,and the effectiveness of the proposed method for reducing sensitivity temperature drift is verified.The results show that,within the tempera-ture range of 300℃to-296℃,the sensitivity temperature drift of the sensor is less than±3.76%.Therefore,the sensor designed in this paper demonstrates excellent stability and high measurement accuracy in low-temperature environments.关键词
