On the basis of traditional double-sided four-beam structure

a high-range acceleration sensor structure is optimized and designed

with measuring range of 10 000 gn.Theoretical analysis of the stress is performed to verify the rationality of the structure

and static structural analysis

modal analysis

and anti-overload capability analysis of the sensor are performed through finite element modeling.Under the condition of constant voltage source power supply

the natural frequency of the sensor is greater than 50 kHz

the theoretical sensitivity value is 18.88 μV/gn

and the anti-overload capability is 20 000 gn.Compared with the traditional structure

it greatly improves the performance of high-range acceleration sensors.
