Intangiriro

GRMS ni agaciro k’umuzi k’ubwiyongere bwa kare kare kagaragazwa mu bice bya g. Ariko, mu buhanga bwo guhindagura, ishobora kwerekeza ku kwihutisha muri rusange kw’ahantu hahindagurika hatunguranye, cyangwa ishobora kugaragara mu bipimo bya moteri yo guhindagura kugira ngo igaragaze umusaruro upimwe mu bihe byihariye by’igeragezwa. Ibyo byombi ntibishobora kugereranywa neza hashingiwe ku bice byonyine.

Iyi nkuru isobanura icyo GRMS isobanura, ibice byayo, n'uko ibarwa. Isobanura kandi uburyo injeniyeri zigomba gusobanura amakuru ya Grms mu bipimo bya moteri ntoya n'imiterere igomba kwemezwa mu kugereranya ibisubizo by'ibizamini. Nk'uruganda rukora moteri ntoya, LEADER ishyira ahagaragara ibipimo by'imitingito ku miterere ijyanye nayo mu nyandiko z'ibicuruzwa byayo; aya makuru agomba kumvikana hamwe n'imiterere yihariye n'imiterere y'ibizamini.

GRMS ni iki?

GRMS ni agaciro kare kare k'ikimenyetso cyo kwihutisha, gikunze kugaragazwa nka gRMS. Mu igerageza ry'ihindagurika ry'ikirere, isobanura muri make ukwihutisha kwa RMS muri rusange mu rugero rwa frequencies. Mu bipimo bya moteri yo kwihutisha, Grms ishobora kandi kwerekana umusaruro wo kwihutisha upimwe mu bihe byihariye by'igerageza.

Iyo ubonye GRMS cyangwa Grms, intambwe ya mbere ni ukwemeza ibirimo gupimwa: ese amakuru asobanura ibidukikije byo guhindagura igikoresho gikorerwamo, cyangwa umusaruro wo guhindagura ukorwa na moteri ubwayo? Nubwo ubwo bwoko bubiri bw'amakuru bukoresha ibipimo bisa, intego zo gupima n'imiterere y'ibizamini biratandukanye, kandi ntibishobora kugereranywa mu buryo butaziguye hashingiwe ku gaciro k'imibare gusa.

Izina ryuzuye n'igice cya GRMS ni iki?

Muri rusange GRMS yerekeza ku kwihutisha RMS (Root Mean Square) igaragazwa mu bice bya g. RMS ni uburyo bwo kubara bwo gutunganya ibimenyetso bitandukanye; g ni igice cyo kwihutisha imbaraga rukuruzi, naho 1g ingana na 9.81m/s29.81m/s2.

Mu nyandiko z’ubuhanga, ikunze kwandikwa nka gRMS, Grms, cyangwa GRMS. Hatitawe ku nyandiko yakoreshejwe, hagomba gusuzumwa aho ikoreshwa kugira ngo hemezwe ko igipimo kigaragaza kwihuta, atari ukwimuka kw’ihindagurika ry’ihindagurika, umuvuduko, cyangwa umuvuduko wa moteri. Ku bisobanuro bya moteri, uburyo bwo gupima n’imiterere y’icyitegererezo gihuye nabyo bigomba gusuzumwa.

GRMS ibarwa ite?

GRMS ishobora kubarwa uhereye ku makuru yo kwihutisha igihe cyangwa uhereye ku murongo wa PSD ukoresha frequency-domain. Uburyo bwa "time-domain" bushingiye ku rukurikirane rw'ibipimo byo kwihutisha; uburyo bwa PSD buhuza ubucucike bwa "acceleration spectral" ku rugero runaka. Ubwo buryo bwombi busaba ibisobanuro bisobanutse neza by'urutonde rw'amakuru n'imiterere y'ibizamini.

Kubara uhereye kuri Time-Domain Acceleration Data

Ku makuru yatanzwe mu buryo bw'igihe, kwihutisha RMS bingana n'umuzi kare w'impuzandengo y'ingero zose z'ihutisha kare:

aho a1a1 binyuze kurianni ingero zo kwihutisha na nˉnˉ ni umubare w'ibipimo. Niba ikimenyetso kirimo sensor offset cyangwa ibice bya DC bitakozwe no guhindagura, hagomba gukosorwa mbere yo kubara hakurikijwe uburyo bwo gupima. Iyo amakuru agaragara muri m/s2m/s2, ashobora guhindurwamo ggmu kugabanyaho hafi 9.81.

Kubara uhereye kuri PSD Curve

Isuzuma rya "Random vibration" rikunze gukoresha "acceleration Power Spectral Density" (PSD) kugira ngo risobanure uburyo vibration ikwirakwira mu mihindagurikire itandukanye. Ubusanzwe PSD ni g2/Hzg2/Hz. Mu guhuza PSD ku rugero runaka hanyuma ugafata imizi kare y'agace kari k'ubuso buhuriweho, GRMS iraboneka.

GRMS==√ (Agace ka PSD gahujwe hejuru y'urutonde rw'inshuro zagenwe)

Igice cy’agace ka PSD gahujwe ni g2g2, kandi gufata umuzi kare bitanga gRMS. Ku mirongo igizwe n’ibice byinshi bya frequency n’imirongo itandukanye, ubuso bwa buri gice bugomba kubarwa ukwabwo hakoreshejwe uburyo bukwiye, bugashyirwa mu byiciro, hanyuma hagafatwa umuzi kare. Imibare nyayo igomba gukurikiza uburyo bukoreshwa bwo gupima cyangwa gusesengura porogaramu. Intera ya frequency na yo igira ingaruka ku musaruro wa nyuma, bityo iyo ugereranije agaciro ka GRMS kabiri, yemeza ko interi ya frequency imwe n’imiterere ya PSD byakoreshejwe.

Ni irihe tandukaniro riri hagati ya GRMS, G Peak, na Peak-to-Peak?

GRMS, G Peak, na Peak-to-Peak bivuga imiterere itandukanye y'ikimenyetso cyo guhindagura kandi muri rusange ntigishobora guhindurwa mu buryo butaziguye. GRMS ihagarariye ukwihuta kwa kare kw'igipimo cy'ikimenyetso; G Peak ihagarariye ukwihuta gukomeye ako kanya mu gihe cyo gupima; Peak-to-Peak ihagarariye itandukaniro riri hagati y'agaciro ntarengwa n'akatari gake.
