The impact of external environmental factors on centrifuge stability was analyzed under working condition,and the influences of environmental temperature,angular inclination modification and linear vibration of foundation on the specific force generated by centrifuge were discussed respectively.The results show that three kinds of errors should be real-time monitored and measured while inertial devices are calibrated on the centrifuge,and the calibration accuracy of inertial devices on centrifuge can be improved through making compensation for these errors.
