O'rnatish rezonansiga ta'siri
Har bir akselerometrning rezonans chastotasi ideal (bolt bilan mahkamlash) o'rnatish uchun ko'rsatilgan. Kamroq qattiq o'rnatish usullaridan foydalanilganda, o'rnatish elastiklik (yay effekti) qo'shgani uchun tizim rezonans chastotasi pasayadi.

O'rnatish usullari — Odatiy rezonans qiymatlari
| O'rnatish usuli | Odatiy o'rnatilgan rezonans | Factor k | Foydalanish mumkin bo'lgan diapazon (±3 dB da) |
|---|---|---|---|
| Stud mount | 28–32 kHz | 0.90–0.95 | ~10 kHz |
| Yupqa yopishqoq qatlam | 18–22 kHz | 0.60–0.70 | ~6–7 kHz |
| Yopishqoq prokladka (qalin) | 12–16 kHz | 0.40–0.50 | ~4–5 kHz |
| Flat magnet | 6–8 kHz | 0.20–0.25 | ~2–2.5 kHz |
| Ikki qutbli magnit | 3–5 kHz | 0.10–0.15 | ~1–1.5 kHz |
| Zond uchi / qo'lda ushlab ishlash | 1.5–2.5 kHz | 0.05–0.08 | ~0.5–0.8 kHz |
ℹ️ Amaliy qoida: Use only up to 1/3 of the mounted resonance frequency for measurements within ±3 dB accuracy. For ±1 dB, use only 1/5. For highest accuracy (±0.5 dB), use only 1/10.
Amaliy tavsiyalar
- Marshrut bo'yicha monitoring: Magnitli o'rnatish keng tarqalgan — ~2 kHz gacha (120 000 CPM) bo'lgan chastotalarda qabul qilinadi
- Doimiy monitoring: Maksimal o'tkazish kengligi va takrorlanuvchanligi uchun har doim shtift o'rnatishdan foydalaning
- Quick checks: Probe tip is okay for low-frequency measurements (1× and 2× on slow machines)
- Podshipnik tahlili: Yuqori chastotali konvert deteksiyasi uchun shtift yoki yupqa yopishqoq o'rnatish talab etiladi
⚠️ Important: Sensor massasi o'lchash nuqtasidagi konstruksiya massasining <10% dan oshmasligi kerak. Yengil konstruksiyalarga o'rnatilgan og'ir sensorlar o'rnatilgan rezonansni yanada kamaytiradi va o'lchanayotgan tebranishni o'zgartirishi mumkin.
Shtift, magnet va yopishqoq o'rnatish imkoniyatlariga ega professional akselerometrlar va tebranish analizatorlari.
