High-gn acceleration sensor is widely used to measure shock acceleration.The requirement of high-gn accelerometer is summarized.Structure principle of piezoelectronic high-gn acceleration sensor is introduced.Design project of high-gn piezoelectronic accelerometer is introduced.A high-gn accelerometer with compressed structure and doible shield which uses piezoelectronic quartz material to transform energy is developed

Test is carried though by using MAXITE impact machine and HOPKINSON bar.Experiment shows that the accelerometer’s dynamic range is 0

1

50 000 gn

work frequency range is 0

2

0 kHz and linearity is less than 10 %

the requirement of guided missile can be accord with.
