摘要

比对是确定不同装置与不同方法之间一致性的主要方法，本文主要论述了基于激光绝对法校准的不同冲击激励系统校准结果比对可行性的问题。首先依据ISO16063-13标准规定的基于刚体碰撞与基于Hopkinson杆的冲击激励系统，分析了其基本原理与典型冲击波形；然后比较了同一只传感器在两种装置上校准结果,说明了结果的差异并分析了原因。最后提出了不同冲击激励系统之间可比性的方法，为冲击校准实验室、区域以及国际比对提供参考。

Abstract

Comparison of calibration results is an effective method to confirm the consistency between different devices and methods, the feasibility of primary shock calibration using different shock devices is introduced in the paper. According to ISO16063-13, the principle of two typical shock exciters based on rigid body motion and Hopkinson bar and the chock pulse shape generated by them are presented. Comparison of the results for an accelerometer calibrated with the two exciters is made, and then difference of the results and its cause are analyzed. Finally the paper describes some effective ways for comparison of the shock calibration results using different shock exciter, which may serve as a reference for shock comparison among regional and international shock community.
