Ninawezaje kubadilisha kasi ya mtetemo hadi mkengeuko?

Displacement = Velocity / (2πf), where f is the frequency in Hz. For example, 1 mm/s RMS at 50 Hz gives displacement = 1/(2π×50) = 0.00318 mm = 3.18 μm 0-pk. Peak-to-peak is double the 0-pk value.

Kiwango cha rejeleo cha dB kwa kasi ya mtetemo ni kipi?

The standard reference for vibration velocity in dB is 10⁻⁶ m/s (1 μm/s or 10⁻³ mm/s). The formula is dB = 20 × log₁₀(v / v_ref), where v is the RMS velocity in m/s and v_ref = 10⁻⁶ m/s.

Je, kuna uhusiano gani kati ya thamani za RMS na kilele cha mtetemo?

For a sinusoidal signal, Peak = RMS × √2 (≈ 1.414). Peak-to-peak = 2 × Peak. This relationship only holds exactly for pure sinusoidal vibration.

Ninawezaje kubadilisha mm/s kuwa g (kasi ya msukumo)?

First convert velocity to acceleration: a = v × 2πf. If velocity is in mm/s, divide by 1000 to get m/s, then a = (v/1000) × 2πf gives m/s². Divide by 9.80665 to get g.

Kwa nini ubadilishaji wa mtetemo unahitaji mzunguko?

Kasi, mkengeuko, na msukumo vinahusiana kupitia vitokanavyo vya muda. Kwa kuwa d/dt ya sinusoid katika mzunguko f huzidisha amplitude kwa 2πf, unahitaji mzunguko ili kubadilisha kati ya vipimo hivi.

Uhusiano wa Mtetemo

For a sinusoidal vibration signal at angular frequency ω = 2πf, the three vibration quantities — displacement (d), velocity (v), and acceleration (a) — are related by differentiation:

RMS dhidi ya Kilele dhidi ya Kilele-hadi-Kilele

Kwa ishara safi ya sinusoid:

Peak = RMS × √2 (≈ 1.414)
Peak-to-Peak = 2 × Peak
RMS = Peak / √2 (≈ 0.7071)

Kipimo cha Desibeli (dB)

Kasi ya mtetemo mara nyingi huonyeshwa kwa dB kwa kumbukumbu ya 10⁻⁶ m/s (= 10⁻³ mm/s):

For example, 1 mm/s RMS = 10⁻³ m/s → dB = 20 × log₁₀(10⁻³ / 10⁻⁶) = 20 × 3 = 60 dB.
