Imbalance
Selingkep antarane massa titi lan sumbu puter mriksa gaya sentrifugal sing nambah karo kuadrat kecepatan.
Mechanisme
Selingkep antarane massa titi lan sumbu puter mriksa gaya sentrifugal sing nambah karo kuadrat kecepatan.
Typical symptoms
Getaran radial bisa ngandhut komponen 1× karo phase sing bisa diulang. Satu puncak ora cukup nggawe diagnosis.
Metode pengukuran
Cathet ukuran bearing horizontal lan vertikal karo referensi phase tachometer nalika kecepatan stabil.
Alternative explanations
Eksentrisitas, sumbu sesak dan resonansi juga dapat menghasilkan 1×.
Pengukuran tambahan
Fase, sweep kecepatan dan respons trial-weight di bawah prosedur yang tepat.
Komponen frekuensi yèn mungkin
1× RPM / 60
Kaslahan: tanpa kontek kecepatan, beban, pemasangan lan jalur transmisi, conto iki ora diagnosis. Conto spectrum konseptual, ora model fault lengkap utawa pengukuran padha padha.
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.
