Diagnostic readout

The anomaly does not simply raise vibration everywhere. Instead, it changes the signal shape on the Y-axis most dramatically: impulsive features collapse while overall RMS still edges higher.

Y-axis peak-related shape metrics fall sharply, with crest factor down 63.8% and kurtosis down 74.3% versus nominal runs.
RMS increases on all three axes, led by Y at +17.9%, indicating slightly higher broadband energy despite the loss of large transient spikes.
In the FFT domain, a strong anomaly band emerges near 1236.2 Hz on every axis, with the biggest absolute growth on Y and Z.

Percent-change heatmap across time-domain features

Anomaly relative to nominal means; the Y-axis feature collapse stands out immediately.

Crest factor comparison by axis

Grouped bars show condition means; whiskers span the two runs in each condition.

Kurtosis comparison by axis

The Y-axis drops from heavy-tailed nominal behavior to a much flatter anomaly signature.

RMS shift by axis

Dumbbell view emphasizes the subtle but consistent increase in vibration energy across all axes.

Y-axis FFT: nominal vs anomaly

Use the range buttons to compare low-frequency behavior with the dominant anomaly band around 1236 Hz.

X and Z FFT overlays

Both axes also develop a 1236 Hz band, while X shows additional low-frequency growth.
