摘要
本文基于JJG 233-2008《压电加速计检定规程》的技术要求,根据比较法原理,通过电压比计算出灵敏度。采用振动比较法研究了加速度计灵敏度幅值测量方法,通过数学模型建立,对不确定度分量的来源进行分析和评定,通过系统评定后得出结论:参考条件下(f=160 Hz,a=100 m/s^(2)),U_(rel)=1.4%(k=2);以及通频带(20~2 000)Hz范围下,U_(rel)=2.3%(k=2)。本研究方向未来展望:(1)结合人工智能技术,未来校准系统实现智能化和自适应校准;(2)多轴集成与解耦技术;(3)标准化与不确定度传递模型。
Based on the technical requirements of JJG 233-2008 Verification Regulation for Piezoelectric Accelerometers,the sensitivity is calculated through the voltage ratio according to the comparison method principle.The vibration comparison method was used to study the measurement method of accelerometer sensitivity amplitude.A mathematical model was established to analyze and evaluate the sources of uncertainty components.After system evaluation,the conclusion was drawn:Under reference:Under reference conditions(f=160 Hz,a=100 m/s^(2)),U_(rel)=1.4%(k=2);and over the frequency range of 20 Hz to 2000 Hz,U_(rel)=2.3%(k=2)。Future perspectives of the research direction:①Future calibration systems incorporating artificial intelligence technologies achieve intelligent and self-adaptive calibration capabilities.②Multi-axis integration technology and decoupling technology.③Standardization and uncertainty propagation model.
