Based on the processing results of the data collected by vibration sensor #3, it can be seen that, as the performance of the PRSM degrades, its amplitude value exhibits a decreasing trend and reaches its minimum when the PRSM fails.
The variance values of the vibration signals at Position 1 and Position 2 show an increasing trend as the loading test progresses.
