Vibration analysis (vibroanalysis) serves as a primary non-destructive diagnostic tool for predicting mechanical failure long before physical breakdown occurs.
The diagram shows a Vibration Analysis & Safety System designed to prevent mechanical failures and accidents on roller coasters.
Sensors: Accelerometers mounted on wheel axles, guide wheels, and couplers detect real-time vibrations.
Signal Processing (DAQ & FFT): A high-speed data acquisition card receives signals and uses FFT analysis to detect bearing wear, unbalance, and misalignment.
Safety Logic (SIL-3 PLC): When vibration levels exceed ISO 10816 limits, a redundant SIL-3 PLC trips the safety system.
Actions: Automatically cuts power, applies progressive emergency braking, and locks block zones to prevent collisions.
