Abstract: According to absolute vibration calibration of laser interferometry in ISO16063-34,the calibration method of vibration transducer in fixed temperature was given.A uncertainty evaluation method of vibration calibration in fixed temperature is proposed in this paper.Basing on the effect factors research,the experimental results and experience,the relative expanded uncertainties of complex sensitivity at reference condition are evaluated.This method provides the reference for uncertainty evaluation of temperature sensitivity of vibration transducers in the future,and a basis for the accuracy evaluation of vibration measurement in temperature environment.

Key words: Vibration calibration, Sine-approximation method, Measurement uncertainty, Temperature sensitivity
