根据压缩式加速度传感器的结构建立其有限元模型;并利用ANSYSIO.0软件对加速度度传感器进行仿真计算,分析了压电陶瓷材料的压电常数和弹性柔顺系数对灵敏度和幅频特性的影响;该计算结果为压电陶瓷材料的选择及陶瓷材料制备工艺的改进提供了参考依据。
The finite element model was founded according to the structure of compressive type accelerometer. ANSYSIO. 0 software was exploited in the fnite element method to analyze the influence of piezoelectric constant and elastic coefficient of piezoelectric ceramic material to the sensitivity and amplitude-frequency characteristic. The cal- culated results could be of reference for selecting piezoelectric ceramics and improvi9g the preparation process.
