Question 1

Vibration displacement ni nini?

Accepted Answer

Vibration displacement ni jumla ya umbali kitu kinachozunguka kinasogea kutoka kwa nguvu ya kupumzika. Kawaida inapimwa kwa micrometers (μm) na inaweza kuonyeshwa kama vertex (0-vertex, upeo wa msogeo kutoka mwezoni) au vertex-hadi-vertex (aina nzima ya harakati). Displacement ni muhimu zaidi kwa kutathmini vibration ya frequency nyingi chini ya kuhusu 10 Hz.

Question 2

Tofauti gani kati ya vertex na vertex-hadi-vertex displacement?

Accepted Answer

Vertex displacement (0-vertex) inapima upeo wa msogeo kutoka katikati ya nguvu ya kupumzika katika mwelekeo mmoja. Vertex-hadi-vertex displacement inapima jumla ya aina ya harakati — kutoka kwa upeo mzuri hadi upeo mbaya. Kwa vibration ya sinusoidal, vertex-hadi-vertex ni exact mara mbili ya vertex. Vertex-hadi-vertex ni parameter maalum zaidi kwa kipimo cha displacement.

Question 3

Jinsi gani ya kubadilisha kasi ya vibration hadi kuhamia?

Accepted Answer

To convert velocity (mm/s RMS) to displacement (μm peak-to-peak), use the formula: d_pp = v_RMS × √2 × 1000 / (π × f), where f is the frequency in Hz. The √2 factor converts RMS to peak, and dividing by (π × f) is the integration from velocity to displacement. The factor 1000 converts mm to μm.

Question 4

Uhusiano wa vibration ni gani kati ya kuhamia, kasi na kuongeza kasi?

Accepted Answer

For sinusoidal vibration, displacement, velocity, and acceleration are mathematically related through frequency. Velocity is the time derivative of displacement (v = 2πf × d), and acceleration is the time derivative of velocity (a = 2πf × v). This means higher frequencies amplify acceleration relative to displacement, which is why displacement measurements are preferred at low frequencies and acceleration at high frequencies.

Question 5

Wakati mimi kuwa natumia displacement badala ya kasi kwa ufuataji wa vibration?

Accepted Answer

Displacement ni muhimu kwa ufuataji wa vibration ya frequency nyingi, kawaida chini ya 10 Hz (600 RPM). Katika frequencies nyingi, kasi na kuongeza kasi faida kuwa ndogo sana hata wakati displacement ni muhimu. Mashine ya kasi nyingi kama kuvuta kazi zina karatasi, penzi la kubaridi, na compressor zinazozunguka mara nyingi zinahitaji ufuataji wa displacement. Kasi (mm/s RMS) ni karamu kwa mashine ya kawaida katika aina 10–1000 Hz, ambapo kuongeza kasi ni bora juu ya 1000 Hz.

Parameter	Symbol	Unit	Best Range
Displacement	d	μm (mils)	Frequency nyingi < 10 Hz
Velocity	v	mm/s (in/s)	10 – 1000 Hz
Acceleration	a	m/s² (g)	> 1000 Hz
