摘要：We propose and demonstrate a structural accelerometer based on a fiber Bragg grating Fabry–Perot interferometer that abandons the traditional mechanical structure. External perturbations act directly upon the wound fiber. By tuning the initial winding tension, the clamping component width, and the fiber suspension distance, both the sensitivity and natural frequency of the accelerometer can be adjusted. We derive the theoretical formulations, and the experimental results exhibit close agreement with the simulations. The theoretical expressions for the accelerometer’s sensitivity and natural frequency are confirmed through experiments. The experiment results indicate that adjusting relevant parameters can tune the accelerometer’s natural frequency between 30 and 110 Hz, with a maximum sensitivity reaching 1556.76 rad/g at 30 Hz. Increasing the fiber winding tension effectively reduces sensitivity, thereby expanding the accelerometer’s working bandwidth. The size and sensitivity of the accelerometer can be balanced by adjusting the clamping component width and the suspension distance. This study offers general design guidelines for the development of analogous sensors in the field of fiber optic sensing.
