| Summary: | Aiming at the damage of a Iow-range micro-electro-mechanical system(MEMS) acceleration sensor under tens of thousands of <italic>g</italic><sub>n</sub> overload during the measurement of outer ballistic information of conventional weapons and ammunition, a kind of shrimp claw anti-impact micro-acceleration sensor was proposed, which could realize the index requirements of anti-overload 30 000<italic>g</italic><sub>n</sub> and range 50<italic>g</italic><sub>n</sub>. The finite element simulation results show that the displacement of the sensor is 0. 99 μm and the sensitivity is 0.124 pF/<italic>g</italic><sub>n</sub> under 50<italic>g</italic><sub>n</sub> load. The maximum equivalent stress of the acceleration sensor under 30 000<italic>g</italic><sub>n</sub> overload is reduced from 1 022.5 MPa to 84.326 MPa, which effectively improved the reliability of the sensor. |
