Warp knitting tau yog lub hauv paus ntawm textile engineering rau ntau tshaj 240 xyoo, evolving los ntawm precision mechanics thiab nruam khoom innovation. Raws li kev xav tau thoob ntiaj teb rau cov khoom zoo warp knitted fabrics loj hlob, cov tuam txhab ntsib kev nyuaj siab los txhawb kev tsim khoom yam tsis muaj kev cuam tshuam qhov tseeb lossis cov ntaub zoo. Ib qho kev sib tw tseem ceeb nyob hauv plawv ntawm lub tshuab knitting - lub zuag lub siab ceev transverse txav mechanism.

Nyob rau hauv niaj hnub high-speed warp knitting tshuab, lub zuag qhia tag nrho ceev lateral motions tseem ceeb rau ntaub tsim. Txawm li cas los xij, raws li lub tshuab ceev tshaj 3,000 rotations ib feeb (rpm), transverse vibrations, mechanical resonance, thiab suab nrov nce. Cov xwm txheej no ua rau muaj kev phom sij rau qhov chaw ntawm lub zuag ntsis thiab ua rau muaj kev pheej hmoo ntawm kev sib tsoo ntawm rab koob, xov paj tawg, thiab txo cov ntaub zoo.

Txhawm rau ua kom tau raws li cov kev sib tw engineering no, kev tshawb fawb tsis ntev los no tau tsom mus rau kev soj ntsuam kev vibration, kev ua qauv zoo, thiab cov txheej txheem simulation qib siab los ua kom zoo dua comb txav. Tsab ntawv xov xwm no tshawb txog qhov kev nce qib thev naus laus zis tshiab, kev siv tswv yim, thiab cov lus qhia yav tom ntej hauv comb transverse vibration control, underscoring the lag luam txoj kev cog lus rau precision engineering thiab sustainable, high-performance daws.

Technology Advancements hauv Comb Vibration Control

1. Dynamic Modeling ntawm Comb System

Ntawm qhov tseem ceeb ntawm optimizing zuag kev ua tau zoo yog kev nkag siab meej ntawm nws tus cwj pwm dynamic. Lub zuag qhia tag nrho txoj kev txav mus los, uas tau tsav los ntawm cov tshuab hluav taws xob tswj hluav taws xob, ua raws li cov qauv kev sib txuas ua ke nrog kev txhais lus thiab oscillation. Thaum lub sijhawm ua haujlwm siab, qhov kev txav mus los no yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev vibration ntau dhau thiab ua haujlwm tsis raug.

Cov kws tshawb fawb tau tsim ib qho yooj yim, ib-degree-ntawm-kev ywj pheej dynamic qauv tsom rau lub zuag lub lateral txav. Tus qauv kho lub comb los ua ke, coj rails, thiab txuas cov khoom raws li lub caij nplooj ntoos hlav-damping system, cais cov thawj yam uas cuam tshuam kev co. Los ntawm kev txheeb xyuas huab hwm coj, nruj, damping coefficients, thiab sab nraud excitation rog los ntawm servo lub cev muaj zog, engineers tuaj yeem kwv yees cov lus teb tsis tu ncua thiab nyob ruaj khov nrog qhov tseeb.

Lub hauv paus theoretical no ua rau txoj hauv kev zoo rau kev tswj kev vibration, coj kev txhim kho kev tsim kho thiab kev ua haujlwm zoo.

2. Kev txheeb xyuas cov peev txheej vibration thiab kev pheej hmoo ntawm kev cuam tshuam

Transverse vibrations feem ntau yog los ntawm cov zuag cov lus tsa suab nrawm nrawm thaum lub sijhawm tsim cov ntaub. Txhua qhov kev hloov pauv qhia qhia lub zog hloov pauv, nthuav dav los ntawm lub tshuab ceev thiab zuag loj. Raws li lub tshuab nrawm nce ntxiv kom ua tau raws li cov hom phiaj tsim khoom, qhov zaus ntawm cov rog no ua rau muaj kev pheej hmoo ntawm resonance-ib qho xwm txheej uas qhov kev tawm dag zog sab nraud cuam tshuam rau lub cev ntau zaus, ua rau tsis muaj kev vibrations thiab kev ua tsis tiav.

Los ntawm kev tshuaj xyuas cov qauv siv ANSYS Workbench simulation cov cuab yeej, cov kws tshawb fawb tau txheeb xyuas qhov tseem ceeb ntawm cov khoom siv hauv cov qauv zuag. Piv txwv li, plaub-txheej ntuj zaus tau xam ntawm kwv yees li 24 Hz, sib xws rau lub tshuab ceev ntawm 1,450 rpm. Qhov ntau zaus no nthuav tawm thaj chaw muaj kev pheej hmoo resonance, qhov chaw ua haujlwm ceev yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev ntxhov siab.

Xws li daim ntawv qhia meej meej tso cai rau cov tuam txhab tsim cov kev daws teeb meem uas txo cov suab nrov thiab tiv thaiv lub tshuab kom ntev.

3. Kev ntsuas kev vibration Mitigation Engineering
