Paper Abstract

A precision centrifuge is used to test and calibrate accelerometer model parameters. Its dynamic unbalance may cause the perturbation of the centrifuge to deteriorate the test and calibration accuracy of an accelerometer. By analyzing the causes of dynamic unbalance, the influences on precision centrifuge from static unbalance and couple unbalance are developed. It is considered measuring and balancing of static unbalance is a key to resolving a dynamic unbalance problem of precision centrifuge with a disk in structure. Measuring means and calculating formulas of static unbalance amount are given, and balancing principle and method are provided. The correctness and effectiveness of this method are confirmed by experiments on a device under tuning, thereby the accurate and high-effective measuring and balancing method of dynamic unbalance of this precision centrifuge was provided.
