New Method Detects Rolling Bearing Faults Before Catastrophic Failure Strikes
The researchers studied how rolling bearings behave when they have a problem. They found that by looking at something called the Lyapunov exponent, they could tell when the bearing was faulty. The Lyapunov exponent changes depending on the state of the bearing, so it can be used to figure out what's wrong with it. This means that by measuring the Lyapunov exponent, we can diagnose faults in rolling bearings.
