Lochnach meachanaich
Cleachdadh sneachta no aiseirigh air a' chnoc creidsinn nonlinear agus comas.
Mechanism
Cleachdadh sneachta no aiseirigh air a' chnoc creidsinn nonlinear agus comas.
Symptoms a-mhàin
Feumaidh harmainic, buannachd agus faisean atharrachadh a bhith a’ tòrtach. Feumaidh an t-sìomanan a bhith a’ atharrachadh le bhoghadh.
Measur method
Inspect the waveform alongside the spectrum; compare foundation and bearing locations
Alternative explanations
Smuineadh, achoineas agus comhchoinneamh sensoríthe a dhéanamh le h-earraí harmonacha.
Additional measurements
Fhoirmeas toradh, cleachdadh craic, cleachdadh cleachdadh agus shùilean deagh-chleachdadh.
Componan fhreagairteach a-staigh
1×, 2×, 3× …; subharmonics possible
Lìonachaisean: airson gu bheil am spèid, a' chur le chéile, aithris agus a-chur-thogail ann an cànan, chan eil na h-èifeachdannan seo diagnoses. Chan eil na h-amplean speactra comhradh-chleachdadh no measan airson a' chnoc.
SIMULATED · NOT LIVE TELEMETRY
Vibration / FFT
Model and assumptions
512 samples; deterministic sinusoids and seeded noise. FFT is one-sided peak amplitude, not RMS. Δf = fs/N. Hann coherent gain is corrected; spectral leakage can remain. The 4.7× component is not a physical bearing-fault model.
Educational model. Results are not sufficient to diagnose a machine or establish safe operating limits.
