The shock exciter based on drop hammer is described, including its structure and principles. Combing with digitizer and virtual instrument, the shock comparison calibration system is established coincided with the method recommended by ISO16063—22. A comparison of shock waveform generated by the standard based on drop hammer and Hopkinson bar is carried out. And also the consistent calibration result between comparison method and primary method valid the reliability of the device, and finally the difference between vibration and shock calibration was discussed.%阐述了基于落锤式冲击加速度标准装置的结构及试验原理,基于相应的数字化仪硬件,结合虚拟仪器技术,按照ISO16063-22冲击比较法校准标准的要求设计了相应的校准软件,实现了加速度计冲击比较法校准.并且与基于Hopkinson杆的冲击激励系统产生的冲击波形进行了比较分析,通过试验数据验证了该冲击加速度标准装置的可靠性,同时对振动与冲击2种校准方式进行了比较并说明了校准结果差异的原因.
