摘　　要：加速度传感器广泛用于振动测量和监视。为了保证测量结果的真实可靠,需要对加速度传感器进行有效的量值溯源。目前,加速度传感器校准主要采用逐点比较法。由于该方法只能得到特定频率和特定加速度幅值下的灵敏度,而在实际测量中真正的纯正弦振动几乎不存在,且人们更关注整个振动频率范围内的振动幅频特性,因此,本文提出了一种加速度传感器通频频率响应特性的校准方法。Acceleration transducers are widely used in vibration measurement and monitoring.In order to ensure the truth of the quantity, it is necessary to be effective for acceleration, such as source plus sub transducer pre-known return point method calibration.It is applied that the step point method calibration can only obtain the sensitivity under specific frequency and specific acceleration amplitude, while the real pure sine almost does not exist in real measurement, and people pay more attention to the vibration amplitude frequency characteristics in a vibration frequency range.In this paper, a calibration method of the direct frequency response characteristics of the acceleration transducer is proposed.
