Optimization design for medium-high frequency FBG accelerometer ...

A simple empirical equation of rotational stiffness for single-notch circular flexible gemel is proposed. Based on the parameter optimization, we have discussed how to choose the structural parameters to achieve the balance between the sensitivity and the eigenfrequency. By using sequential quadratic programming (SQP) method, two prototypes of FBG accelerometers with eigenfrequency of 650 Hz and 3050 Hz are designed. Furthermore, we also perform the shaking table test for the fabricated prototyp
