Cia kuv txiav mus rau qhov kev sib tw: yog tias koj tab tom nrhiav kev vibration hais lus tsav tsheb rau cov rooj zaum zaws thiab tsuas yog muab piv rau tus nqi thiab lub sijhawm ua haujlwm, koj tab tom teeb tsa koj tus kheej kom muaj teeb meem. Nyob rau hauv 17 xyoo Xuanda Electronics (XDEC) tau tsim kev vibration hais lus tsav tsheb, peb tau pom ntau lub npe tau kub hnyiab los ntawm tus neeg muag khoom hloov pauv - tsis yog vim lawv xaiv lub Hoobkas tsis raug, tab sis vim lawv tsis paub cov lus nug dab tsi los nug ua ntej kos npe rau daim ntawv cog lus.
Cov lus qhia no yog rau cov thawj coj ntawm kev yuav khoom thiab cov khoom lag luam coj ntawm lub rooj zaum zaws cov khoom lag luam uas xav tau los ntsuas kev vibration tsav cov neeg xa khoom. Tsis muaj fluff. Nov yog 5 qhov pitfalls ntau tshaj plaws - thiab yuav ua li cas kom zam tau lawv.
Pitfall 1: Qauv ≠ Production (Qhov teeb meem "Ob-Face")
Koj tau txais cov qauv zoo nkauj uas dhau txhua qhov kev xeem. Tab sis thaum thawj cov khoom lag luam tuaj txog, qhov kev vibration siv tau tawm los ntawm 15% - tsis muaj zog heev ntawm qee qhov chaw, hnyav rau lwm tus. Dab tsi tshwm sim?
Feem ntau cov chaw tsim khoom siv cov ntaub ntawv hwm zoo thiab phau ntawv calibration rau cov qauv, tom qab ntawd hloov mus rau cov khoom siv tsis siv neeg- ntau lawm nrog cov khoom siv qis dua. Kev kam rau siab ntawm "± 3dB" ntawm daim ntawv tuaj yeem yog ± 8dB hauv kev tsim khoom loj.
Yuav zam tau li cas:Thov cov ntaub ntawv tshuaj xyuas rau3 sib law liag ntau lawm batch, tsis yog ib qho qauv batch xwb. Ua tib zoo mloog rau rhiab heev (dB / W / m), Fs (resonance zaus), thiab Qms (tus neeg kho tshuab zoo). Yog tias tus neeg muag khoom tsis kam, qhov ntawd yog tus chij liab.
Pitfall 2: Vibration Performance Parameters ua yuam kev
Tsis zoo li lub suab hais lus li niaj zaus, lub rooj zaum zaws lub rooj tsav tsheb yuav tsum tau qis - zaus, siab - amplitude kev co. Cov ntsiab lus tseem ceeb tsis yog qhov rhiab heev - lawvF0 (resonance zaus)thiabqhov siab tshaj plaws excursion.
Peb tau pom cov npe tshwj xeeb "F0=50Hz" uas ntsuas tau ntawm 80-100Hz. F0 siab dua txhais tau hais tias qhov tsawg - zaus vibration xav tias tsis muaj zog - cov neeg siv lub rooj zaum zaws yuav yws cov cuab yeej "tsis ua haujlwm." Qee qhov specs sau "max excursion" tab sis tshem tawm cov zaus thiab lub zog hluav taws xob raws li nws tau ntsuas.
Yuav zam tau li cas:Nug rauzaus teb nkhausthiab qhov tseeb F0 ntsuas. Cov neeg muag khoom tshaj lij muab Thiele-Me me (T/S) tsis zoo rau cov tsav tsheb vibration. Yog tias lawv ua tsis tau lossis tsis qhia cov ntaub ntawv no, txav mus rau.
Pitfall 3: Vague Lead Time cog lus
Kev vibration tsav tsheb ua lub sij hawm yog qhov nyuaj dua li tus qauv tsav tsheb vim tias lawv koom nrog kev sib nqus hluav taws xob sib nqus, lub suab coil winding, thiab kev sim ua raws - txhua kauj ruam ntxiv sijhawm. Thaum lub Hoobkas hais tias "15-hnub xa khoom," qhia meej seb qhov ntawd pib txij hnub xaj, hnub pom zoo qauv, lossis hnub tau txais nyiaj tso nyiaj.
Qhov phem tshaj: qee lub tsev lag luam deprioritize me me kev co tsav tsheb xaj kom pom zoo ntawm cov tsav tsheb loj dua. Koj lub sijhawm ua haujlwm 15-hnub tuaj yeem ncav cuag 30-45 hnub.
Yuav zam tau li cas:Thov kom ntxawssijhawm ntau lawmnrog cov ntsiab lus tseem ceeb: kev teeb tsa, lub suab coil winding, sib nqus Circuit Court sib nqus, hlawv- hauv kev sim, thiab kev soj ntsuam zaum kawg. Tau txais cov hnub no kaw rau hauv daim ntawv cog lus nrog cov nqe lus nplua rau kev ncua.
Pitfall 4: Hidden NRE (Tsis yog-Recurring Engineering) Nqi
Massage lub rooj zaum vibration tsav tsheb feem ntau xav tau kev hloov kho - qhov ntev ntawm kev cai, mounting brackets, cable connectors, los yog kev kuaj ua raws. Qee lub tuam txhab hais txog tus nqi qis, tom qab ntawd ntaus koj nrog kev npaj txhij txog nqi nruab nrab ntawm - ntau lawm: "Cov khoom siv diaphragm no xav tau kev tsim tshwj xeeb," "Koj qhov txuas spec xav tau pwm tshiab."
Thaum koj tau nqis peev lub sijhawm tsim thiab tsim cov cuab yeej, koj tau daig.
Yuav zam tau li cas:Xav tau aua kom tiav cov nuj nqisua ntej kos npe: cov nqi pwm pwm, cov khoom siv ntxiv, cov nqi kuaj, nqi ntawv pov thawj, thiab cov nqi ntim khoom. Tus neeg muag khoom pob tshab muab qhov ua ntej no - kev xav tsis thoob hauv kev tsim khoom loj yog ib qho kos npe ntawm lub Hoobkas tsis ua haujlwm.
Pitfall 5: Tshaj tawm-Kev Txhawb Kev Muag Khoom Tsuas yog Cov Lus Cog Tseg
Thaum tus tsav tsheb vibration tsis ua haujlwm, kev kuaj mob tsis yooj yim - tsis zoo li lub suab hais lus uas "tsis muaj suab" yog qhov pom tseeb, teeb meem kev vibration tuaj yeem tshwm sim los ntawm lub suab coil, ncua kev kawm, sib nqus Circuit Court, lossis txuas txuas. Qee tus neeg muag khoom tsis teb tom qab muag: "Qhov ntawd tsis yog peb qhov teeb meem zoo" lossis "Peb yuav rov qab rau koj" - thiab yeej tsis ua.
Yuav zam tau li cas:Ua ntej muab qhov kev txiav txim, paub meej tias tus neeg muag khoomtsis raws cai tus qauv(Industry benchmark: Tsawg dua lossis sib npaug li 1%) thiabteb ncua sij hawm(kev lag luam benchmark: lub hauv paus ua rau tsom xam nyob rau hauv 7 hnub ua hauj lwm). Yuav tsum tau tsim cov theem pib (100-200 units) ua ntej cog lus rau tag nrho ntim.
💡 Tswv yim tswv yim:Cov txheej txheem hloov pauv kev nyab xeeb tshaj plaws muaj 3 kauj ruam: ① Thov cov ntaub ntawv los ntawm 3 cov khoom sib law liag; ② Khiav 3- hli tsav (100-200 units); ③ Scale kom puv ntim tsuas yog tom qab tus tsav hla dhau. Hla cov kauj ruam 1 thiab 2 yog qhov txaus ntshai rau cov tsav tsheb vibration.

FAQ: Kev vibration tsav xaiv rau cov rooj zaum zaws
Q1: Dab tsi F0 yog qhov tsim nyog rau lub rooj zaum zaws vibration tsav tsheb?
A: Rau cov rooj zaum zaws, koj xav tau qis - zaus, siab - amplitude vibration. F0 (resonance zaus) feem ntau pom zoo kom tsawg dua lossis sib npaug li 60Hz. Qhov qis dua F0, qhov zoo dua qhov qis - zaus vibration nyhuv. F0 saum 80Hz yuav hnov "lub teeb" thiab tsis muaj txiaj ntsig rau cov neeg siv.
Q2: Puas yog kev vibration tsav rhiab heev specs ntsuas tib yam li cov tsav tsheb tsis tu ncua?
A: Chav tsev (dB / W / m) yog tib yam, tab sis txoj kev ntsuas txawv. Cov neeg tsav tsheb vibration feem ntau yog ntsuas los ntawm kev sib cuag sensor lossis accelerometer ntawm qhov kev sim ntsuas, tsis yog nyob rau hauv lub chamber anechoic. Paub meej txog txoj kev sim nrog koj tus neeg xa khoom - txoj kev ntsuas tsis sib haum ua rau cov specs sib piv tsis sib xws hauv cov chaw tsim khoom.
Q3: Cov ntawv pov thawj dab tsi ua lub rooj zaum zaws lub rooj tsav tsheb xav tau?
A: Rau Tuam Tshoj ua lag luam: RoHS yog tus qauv. Rau EU/USA export: CE, UL yuav tsum tau. Rau kev kho mob-qib cov rooj zaum zaws: FDA lossis cov ntawv pov thawj khoom siv kho mob cuam tshuam yuav raug siv. Cov ntawv pov thawj yuav tsum sib txawv raws li kev lag luam - qhia meej nrog koj tus neeg muag khoom thaum ntxov.
Q4: Vim li cas tus nqi tsis zoo rau cov tsav tsheb vibration siab dua li cov tsav tsheb tsis tu ncua?
A: Cov neeg tsav tsheb vibration ua haujlwm ntawm qhov tsawg zaus nrog siab amplitude - qhov no ua rau muaj kev ntxhov siab heev rau lub suab coil, lub kaw lus ncua, thiab sib nqus Circuit Court. Tsis tas li ntawd, ntau lub rooj zaum zaws vibration tsav tsheb yog kev cai - qhov loj me, xav tau cov cuab yeej siab dua. Xaiv lub Hoobkas nrog anplooj siab vibration tsav tsheb ntau lawm kab, tsis yog ib qho uas khiav kev vibration xaj ntawm tus txheej txheem suab tsav kab ua haujlwm sab.
Q5: Dab tsi yog qhov txawv ntawm tus neeg hais lus kev vibration thiab ib txwm muaj -ntau tus hais lus tsav tsheb?
A: Qhov sib txawv tseem ceeb yog lub hom phiaj ntawm kev thov. Ib txwm muaj tag nrho - tus tsav tsheb ntau lub hom phiaj cov lus teb tiaj tus thiab lub suab zoo. Tus tsav tsheb vibration tsom rau qis- zaus, siab- amplitude, kev co ruaj khov. Raws li kev tsim qauv, cov neeg tsav tsheb vibration siv cov tshuab hluav taws xob softer (silicone es tsis yog ntaub- roj hmab) thiab cov qauv kev mus ncig ntev dua, nrog cov hlau nplaum sib nqus ua kom zoo rau qis - zaus ua haujlwm.
Dab tsi ntawm cov neeg tsav tsheb vibration muaj kev txhawj xeeb rau koj feem ntau - zoo ib yam, lub sijhawm ua haujlwm, lossis kev hloov kho? Tso ib nqe lus thiab cia peb tham.
