Poor Information Evaluation of Friction Torque Test on Bearing for Space Application(ⅡEzperiment)

摘要：

Based on the grey system theory and bootstrap theory and by the more-than-one-year analysis of the experimental data of friction torque, we separately predict the fifths and the eighth years friction torque and their own fluctuant interval, and we can also offer the forecast errors and the confidence level.Many studies on the experiments of components and flywheels life span have shown that the confidence level in the 5 years is above 95％ and still above 93％ in the 8 years.Flywheels friction torque will change from 0.2778 to 0.3509 and the component s friction torque from 0.1799 to 0.2729.The maximum of relative error of the forecasting result is 0.55％.
