Ruxsat etilgan tebranish tezligi (ISO 10816)
ISO 10816 / ISO 20816 bo'yicha ruxsat etilgan tebranish tezligi chegaralarini aniqlang. Mashina sinfini tanlang, o'lchangan tezlikni kiriting va A/B/C/D zona bahosini oling.

Tebranish tezligining o'rtacha kvadratik qiymati (RMS)
Tebranish tezligining RMS qiymati maksimal tezlik bilan quyidagi munosabat orqali bog'liq:
- vRMS — o'rtacha kvadratik tebranish tezligi (mm/s)
- vpeak — maksimal tebranish tezligi (mm/s)
ISO 10816 mashinaning tebranish ziddiyatini keng diapazonli tebranish tezligi v asosida baholaydiRMS (odatda 10–1000 Hz). Mashinalar to'rt guruhga bo'linadi va har bir guruh to'rtta baholash zonasiga ega (A, B, C, D).
ISO 10816 zona chegaralari — barcha sinflar
| Zone | Class I (≤15 kW) | Class II (15–75 kW) | Class III (qattiq, >75 kVt) | Class IV (egiluvchan, turbo) |
|---|---|---|---|---|
| A (New) | ≤ 0.71 | ≤ 1.12 | ≤ 1.8 | ≤ 2.8 |
| B (Acceptable) | 0.71 – 1.8 | 1.12 – 2.8 | 1.8 – 4.5 | 2.8 – 7.1 |
| C (Tolerable) | 1.8 – 4.5 | 2.8 – 7.1 | 4.5 – 11.2 | 7.1 – 18 |
| D (Damaging) | > 4.5 | > 7.1 | > 11.2 | > 18 |
Barcha qiymatlar mm/s RMS da.
Amaliy Misol
Given: O'lchangan tebranish tezligi = 3,2 mm/s RMS
Class II boundaries: A ≤ 1.12, B ≤ 2.8, C ≤ 7.1, D > 7.1
3,2 mm/s B chegarasidan (2,8) oshib ketgan, lekin C chegarasidan (7,1) past
Result: Zone C — Faqat cheklangan vaqt davomida qabul qilinadi. Tuzatuvchi chora ko'rish rejalashtirilsin.
