Experimental analysis of performance degradation of solid lubricated bearings with vibration and friction torque signal

Solid lubricated bearing is a key component in space mechanisms, and its performance degradation assessment is very important due to high reliability demands of space mechanisms. In this context, performance degradation assessment is carried with experimental method. Vibration signal and friction torque signal are used to make the assessment. Both results are close to that of dismantling after the experiment.
