The testing system which based on the high measure range accelerometer was designed, and then the overload-data which was tested by a hardened subminiature recorder was chalked up and analyzed. The critical lowpass frequency was established and then the overload acceleration was got using Matlab. The results show that the error of data which was tested and analyzed during penetration was less than 10% and the testing system can work during penetration of double-layers targets.

Abstract

The testing system which based on the high measure range accelerometer was designed, and then the overload-data which was tested by a hardened subminiature recorder was chalked up and analyzed. The critical lowpass frequency was established and then the overload acceleration was got using Matlab. The results show that the error of data which was tested and analyzed during penetration was less than 10% and the testing system can work during penetration of double-layers targets.

Key words

MEMS / high measure range accelerometer / double-layers steel targets / low-pass filter / cut-off frequency
