Abstract

To obtain the high accuracy acceleration inputs for calibration of inertial instruments

the mathematical modeling

measurement and associated uncertainty evaluation of the acceleration produced by a precision centrifuge were investigated. An acceleration measurement model and an associated uncertainty propagation model were established for the 10

-6

order high precision centrifuge. Then

major components

static and dynamic diameters and static and dynamic longitudinal misalignment angles

in the acceleration measurement model were measured precisely by using our proposed methods. Based on identification and quantization of measurement uncertainty sources

the uncertainty evaluation of acceleration measurement was implemented respectively by employing the uncertainty evaluation mathematical model of acceleration and Monte Carlo Method(MCM). Finally

some issues were discussed and summarized on the mathematical model and uncertainty evaluation. Test results indicate that the acceleration relative standard uncertainty of the developed precise centrifuge is less than 310

-6

under the spectrum of 1

g-100g

. The precision of the developed precise centrifuge reaches the international advanced level and the proposed measuring model and associated uncertainty evaluation method can provide some references for other precise centrifuges.
