| Abstract: |
| Objective To provide a method for error analysis of spindle rotation system of precision centrifuge. Methods Based on singular spectrum analysis (SSA), the tendency of system error was extracted. Four high-precision sensors were used to measure the relative position changes of the spindle. Signal reconstruction was decomposed by differential-SSA and the data tendency were obtained, i.e., the spindle rotation system error. Results The tendency by reconstruction was consistent with the measured results at each speed. Conclusion This method could be used to compensate the spindle rotation system error of precision centrifuge. |
