摘　　要：文章将加速度冲击校准分为绝对法、相对法和比较法进行介绍,并给出了几种半正弦冲击脉冲激励装置的激励范围及校准装置的测量范围和测量不确定度。所提出的加速度类比法系冲击校准新方法,是相对法和比较法的结合,能对冲击加速度传感器灵敏度、幅值线性度与频率响应等进行较为准确的检定与校准。This paper introduces the testing principle and method of accelerometer shock calibration, which provides shock sensi- tivity calibration of most accelerometer types at half-sine pulse duration. It＇ s divide into absolute method, relative method and analo- gy comparison method that impact acceleration sensor calibration. Some of shock drive source is introduced, on the other hand, the range and uncertainty of shock calibration is given. The analogy comparison method is a new method of calibrating acceleration, which makes it better to calibrate sensitivity, amplitude linearity and frequency response of impact accelerometer.
