Considering poor information characteristics of friction torque for rolling bearing, a dynamic evaluation method called “from individual identification to population inference model” is proposed in the paper to evaluate the friction torque of bearing for space application. It mainly includes dynamic DGM(1,1) model, new initial value DGM(1,1)(More)
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 fifth's and the eighth year's 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(More)
