The new generation national primary standard device of shock acceleration be studied and established. It can realize high precision calibration of shock accelerometer sensitivity by laser interferometry in the acceleration peak range from 20 m/s2 to 1000000 m/s2 and the pulse-duration range from 20 μs to 200 μs. The device structure and the key technology to be solved are introduced. The control functions of the acceleration-peak and pulse-duration for small-medium shock device are described. The main specifications and experimental results are provided. The new generation national primary standard device can meet the demand of shock quantity traceability in wide range and high accuracy in all areas of the national economy.
