Reading time 1 min

Context

The failure of leaf springs installed on trucks or trains can lead to serious accidents.

Need

The customer wanted to estimate the health indicator that was high before braking, based on vibration measurement: 2 accelerometers placed on each side of the leaf spring, not synchronized.

Solution

DiagFit proposed a 3-state default detection system: green (OK), orange (to be inspected), red (stop vehicle immediately).

Results

Model performance : 100% true positives (2 springs out of 2) and 100% true negatives (5 springs out of 5).
