Warp knitting yanga iri ibwe repakona yeinjiniya yezvipfeko kweanopfuura makore 240, ichishanduka kuburikidza nemakanika chaiwo uye inoenderera mberi yekugadzira zvinhu. Sezvo kudiwa kwepasirese kwemachira emhando yepamusoro-soro akarukwa achikura, vagadziri vanotarisana nekuwedzera kudzvanywa kuti vawedzere kugadzirwa pasina kukanganisa kurongeka kana kunaka kwemachira. Rimwe dambudziko rakakura riri mukati memwoyo wemuchina wekuruka — iwo muzinga unochinjika unochinjika wemuzinga.

Mumichina yemazuva ano yekuruka inomhanya-mhanya, muzinga unoita mafambiro ekukurumidza akakosha pakugadzira machira. Nekudaro, sezvo kumhanya kwemuchina kunodarika zviuru zvitatu zvekutenderera paminiti (rpm), kutenderera kwemhepo, mechanical resonance, uye ruzha runowedzera. Zvinhu izvi zvinokanganisa kumira kwemuzinga uye kuwedzera njodzi yekudhumhana netsono, kuputika kweshinda, uye kuderedzwa kwemhando yejira.

Kusangana nematambudziko einjiniya aya, tsvakiridzo ichangoburwa yakatarisana nekuongorora vibration, ine simba modhi, uye hunyanzvi hwekunyepedzera kukwirisa kufamba kwecomb. Ichi chinyorwa chinoongorora kufambira mberi kwetekinoroji, mashandisirwo anoshanda, uye mafambiro emangwana mucomb transverse vibration control, zvichisimbisa kuzvipira kweindastiri kuhuinjiniya chaihwo uye inogoneka, yepamusoro-soro mhinduro.

Tekinoroji Kufambira mberi muComb Vibration Control

1. Dynamic Modelling yeComb System

Pamusimboti wekugadzirisa kuita kwecomb ndiko kunyatsonzwisisa kwemaitiro ayo ane simba. Iyo comb inochinjika kufamba, inofambiswa nemagetsi inodzorwa actuators, inotevera cyclic pateni inosanganisa lateral dudziro uye oscillation. Panguva yekushanda kwekumhanya-mhanya, iyi cyclic kufamba inofanirwa kudzorwa nekuchenjerera kudzivirira kuzunguza kwakanyanya uye kukanganisa kwenzvimbo.

Vatsvagiri vakagadzira yakapfava, imwe-dhigirii-ye-rusununguko ine simba modhi inotarisisa pane iyo comb's lateral kufamba. Iyo modhi inobata iyo muzinga musangano, njanji, uye yekubatanidza zvinhu sechirimo-inonyorovesa sisitimu, ichitsaura izvo zvakakosha zvinopesvedzera vibration. Nekuongorora huremu, kuomarara, kunyorovesa coefficients, uye ekunze ekuwedzera simba kubva kune servo mota, mainjiniya anogona kufanotaura mhinduro yenguva pfupi uye yakatsiga-yemamiriro emamiriro epamusoro.

Iyi theoretical hwaro inogonesa yakarongeka nzira yekudzora vibration, inotungamira dhizaini gadziriso uye kuita optimization.

2. Kuziva Vibration Sources uye Resonance Risks

Mavhitivhiti akachinjika anonyanya kubva mukufamba kuri kuita muzinga panguva yekugadzira machira. Shanduko yega yega yenzira inounza masimba anochinja, anokwidziridzwa nekumhanya kwemuchina uye comb mass. Sezvo kumhanya kwemuchina kunowedzera kuzadzisa zvinangwa zvekugadzira, ndizvo zvinoitawo kuwanda kwemasimba aya, kukwidza njodzi yekunzwa-mamiriro ezvinhu apo mafambiro ekunze ekuwedzera anowirirana neiyo sisitimu frequency, zvichitungamira kukudengenyeka kusingadzoreki uye kutadza kwemuchina.

Kuburikidza nekuongorora modal vachishandisa ANSYS Workbench simulation maturusi, vaongorori vakaona yakakosha mafirisheni mukati memuzinga. Semuyenzaniso, yechina-yechisikigo frequency yakaverengerwa ingangoita 24 Hz, inoenderana nekumhanya kwemuchina we1,450 rpm. Iyi frequency range inopa resonance risk zone, uko kumhanya kwekushanda kunofanirwa kutariswa nemazvo kudzivirira kusagadzikana.

Yakadaro chaiyo frequency mepu inopa vagadziri simba reinjiniya mhinduro dzinoderedza resonance uye kuchengetedza hupenyu hwemuchina.

3. Engineering Vibration Mitigation Measures

Mazhinji einjiniya mhinduro akatsanangurwa uye akasimbiswa kuti aderedze transverse vibrations mucomb mechanism:

• Resonance Avoidance:Kugadzirisa maumbirwo emuzinga, kugovera kwakawanda, uye kuomarara kwechimiro kunogona kushandura mafambiro echisikigo kunze kwemaitiro ekushanda. Iyi nzira inoda kuenzanisa kusimba uye kushanda kwehurongwa.
• Active Vibration Isolation:Yakasimbiswa mota mounts uye yakagadziridzwa bhora screw dhizaini inosimudzira vibration yekuzviparadzanisa nevamwe. Kuvandudzwa kwekutapurirana chaiko kunovimbisa kufamba kwakapfava muzinga, kunyanya panguva yekuchinja kwekukurumidza kwekutungamira.
• Damping Integration:Tungamira njanji-yakaiswa zvitubu zvekudzoka uye zvinhu zvinonyorovesa zvinodzvanya madiki-vibrations, kudzikamisa muzinga panguva "yekumisa-kutanga" nhanho.
• Optimized Drive Force Input Profiles:Yepamberi yekupinza maprofiles senge sinusoidal acceleration inoderedza kuvhunduka kwemechani uye kuve nechokwadi chekufamba kwakatsetseka, kudzikisa njodzi dzekudhumhana netsono.

Zvikumbiro muIndasitiri

Iko kubatanidzwa kweiyi vibration control tekinoroji inopa mabhenefiti anobatika pane yakakwirira-inoita warp knitting mashandiro:

• Hunhu Hwemucheka Wakawedzerwa:Chaiyo muzinga kudzora inovimbisa kuenderana kuumbwa kwe loop, kuderedza kuremara uye kuwedzera chigadzirwa aesthetics.
• Yakawedzera Kumhanya Kwemuchina neKugadzikana:Resonance kudzivirira uye optimized dynamic mhinduro inogonesa yakachengeteka, yakakwirira-kumhanya kushanda, inosimudzira chibereko.
• Yakaderedzwa Maintenance uye Downtime:Kudzora kuzunguzika kunowedzera hupenyu hwechikamu uye kuderedza kutadza kwemakanika.
• Mashandiro Anoshanda Nesimba:Smooth, optimized comb motion inoderedza kurasikirwa kwesimba uye inovandudza mashandiro ehurongwa.

Ramangwana Trends uye Indasitiri Outlook

Iko kushanduka kwewarp knitting muchina dhizaini inowirirana nemaitiro epasi rose anosimbisa otomatiki, digitalization, uye kusimba. Nzira dzinokosha dzinosanganisira:

• Intelligent Vibration Monitoring:Real-time sensor network uye kufungidzira analytics inogonesa proactive kugadzirisa uye kuita optimization.
• Advanced Materials:Yakakwirira-yakasimba, isingaremi macomposites inozowedzera kuwedzera muchina wekumhanyisa kugona uku uchichengetedza kugadzikana.
• Digital Twin Technology:Virtual modhi inoteedzera mhinduro dzine simba, zvichibvumira kutanga kuoneka kwenyaya dzevibration panguva dzekugadzira zvikamu.
• Sustainable Machine Dhizaini:Vibration control inoderedza kuburitswa kweruzha uye kupfeka kwemuchina, kutsigira kushanda kwesimba uye kunoenderana nenharaunda.

Mhedziso

Yepamusoro-speed warp yekuruka kuita kwemuchina unotsamira pakudzora chaiko kwekufamba kwemuzinga. Tsvagiridzo ichangoburwa inoratidza maitiro ane simba modhi, epamberi simulations, uye hunyanzvi hweinjiniya hunogona kudzikisira kuzunguzika, kuwedzera chigadzirwa, uye kuchengetedza mhando yechigadzirwa. Zviitiko izvi zvinoisa tekinoroji yemazuva ano warp knitting pamberi pekugadzira nemazvo uye zvigadziriso zvemaindasitiri.

Semumwe wako waunovimba naye mu warp knitting innovation, isu tinoramba takazvipira kubatanidza kufambira mberi uku mumichina mhinduro dzinotyaira kuita, kuvimbika, uye kubudirira kwevatengi.
