Resonansi
Respons dadi luwih gedhe nalika eksitasi nglambang nganggo frekuensi alami. Dampak utawa kaku kang governa hasil.
Mechanisme
Respons dadi luwih gedhe nalika eksitasi nglambang nganggo frekuensi alami. Dampak utawa kaku kang governa hasil.
Typical symptoms
Amplitudo ageng lan perubahan fasa bisa terjadi ing wilangan kecepatan yèn wiji.
Metode pengukuran
Kecepatan track, amplitudo lan fasa ing ngendi run-up utau coast-down dikawinkan.
Alternative explanations
Perubahan beban atau eksitasi proses juga bisa menaikkan amplitudo di rentang kecepatan.
Pengukuran tambahan
Pengujian dampak, analisis modal, dan penilaian kaku struktur.
Komponen frekuensi yèn mungkin
excitation ≈ natural frequency
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.
