RPM dan Hz ga o'tkazish
Asosiy chastota (1× tartib) Hz da — aylanish tezligini 60 ga bo'lish orqali aniqlanadi:
Garmonik chastotalar
Har bir garmonik (tartib) asosiy chastotaning butun son katlamidir:
where n — garmonik tartib raqami (1, 2, 3, …).

Tebranishdagi garmonikalarning keng tarqalgan manbalari
| Order | Common Source |
|---|---|
| 1× | Disbalans, egilgan val, ekssentrisitet |
| 2× | Noto'g'ri birlashma (burchakli/parallel), bo'shashish |
| 3× | Noto'g'ri birlashma (kuchli), bo'shashish |
| N× | Pich/qanot o'tish chastotasi (N = qanot soni) |
| Z× | Tishli uzatma to'qnashuv chastotasi (Z = tish soni) |
| ½× | Yog' girdobi, ishqalanish |
| 0.43× | Oil whip |
Amaliy Misol
Given: Tezlik = 3000 RPM
1× = 3000 / 60 = 50 Hz (3000 CPM)
2× = 2 × 50 = 100 Hz (6000 CPM)
3× = 3 × 50 = 150 Hz (9000 CPM)
Period = 1 / 50 = 20 ms
ω = 2π × 50 = 314.16 rad/s
💡 Tip: In vibration analysis, the harmonic spectrum pattern is a key diagnostic tool. Unbalance shows a dominant 1× peak, misalignment shows strong 2× (and sometimes 3×), and bearing defects generate non-synchronous frequencies related to bearing geometry.
