Abstract:
A novel topology leaf spring as a substitute for the traditional spring was designed to expand the effective bandwidth of a seismometer. The finite element analysis showed that the seismometer with the new topology spring has better performance than that with the traditional spring. Compared with the traditional pendulum, the proposed topology structure was featured with lower natural frequency and higher spurious frequency. The bandwidth of the proposed seismometer was enhanced to [2 s, 72 Hz] with an increase of 43% over the traditional seismometer bandwidth of [1 s, 51 Hz] as well as the signal distortion of the seismometer was also reduced with the proposed topology spring.
