Bushings & Dampers TPU Compound | Muaj Kev Ruaj Ntseg Siab, Tiv Thaiv Kev Sib Txhuam
Bushings & Dampers TPU Compound
TPU cov khoom sib xyaw tsim los rautsheb ncua kev kawm bushings, cov ntsiab lus damping, thiabcov khoom siv cais kev co,
qhov twg kev ua tau zoo nyob ntawmkev nqus zog, tswj tau qhov rov qab los, teeb tsa qis compression, thiabkev ruaj khov ntawm cov duab mus sij hawm ntev.
Nplooj ntawv no tsom mus rau yuav ua li cas tso cov khoom siv TPU rauNVH(suab nrov, kev co, kev nplij siab) tus cwj pwm, kev qaug zog ruaj khov, thiab kev tswj qhov ntev ntawm kev txhaj tshuaj molding.
Rau cov bushings thiab dampers, cov khoom siv "zoo tshaj plaws" tsis yog tsuas yog lub zog siab xwb. Nws yog qhov sib npaug ntawm
kev ua siab ntev(rov qab zog),kev ua kom lub cev tsis muaj zog(nqus lub zog), thiabkev tswj hwm cov txheej txheem compression(tuav cov duab thaum muaj kev thauj khoom).
Qhov nyiaj tshuav no ncaj qha cuam tshuam rauNVH xav li cas, kev ruaj khov ntawm kev caij tsheb, thiab lub neej ua haujlwm.

Cov Ntawv Thov Ib Txwm Muaj
- Cov bushings ncua kev kawm: caj npab tswj, cov khoom stabilizer, subframe interfaces (nyob ntawm qhov project)
- Cov ntsiab lus damping: rebound stops, buffer blocks, elastic support parts qhov twg deformation yog nquag
- Cov khoom siv cais kev co: cov qauv mounts lossis cov qauv cais tawm qhov twg kev nplij siab thiab kev tswj suab nrov yog qhov tseem ceeb
- Cov khoom siv elastomer hnav / kov: qhov twg kev sib txhuam, qaug zog thiab kev ruaj khov deformation yuav tsum sib npaug
Kev Xaiv Qib Sai (Daim Ntawv Teev Npe)
Xaiv "Comfort NVH" thaum twg
- Kev cais tawm kev co thiab kev nplij siab thaum caij tsheb yog lub hom phiaj tseem ceeb
- Koj xav tau cov lus teb du thiab txo qhov kev ua phem
- Nruab nrab load thiab deformation ntau yam nrog kev ruaj khov rebound tus cwj pwm
Xaiv "Load & Stability" thaum twg
- Kev tswj cov txheej txheem nias yog qhov tseem ceeb heev nyob rau hauv lub sijhawm ntev static load
- Kev khaws cia cov duab thiab qhov ruaj khov ntawm qhov ntev tsav lub neej kev pabcuam
- Xav tau kev ntxhov siab ntau dua ntawm kev hloov pauv thiab kev tswj hwm rov qab zoo dua
Lus Cim: Qhov chaw kawg nyob ntawm qhov load profile (static vs dynamic), qhov kev teb rau qhov tawv ntawm lub hom phiaj, qhov kub thiab txias, thiab qhov yuav tsum tau kho NVH.
Kev Ua Tau Zoo ntawm NVH: Yam Tseem Ceeb Hauv Kev Xyaum
NVH tsis yog ib tus lej xwb. Hauv cov khoom elastomer, tus cwj pwm NVH los ntawm seb cov khoom siv teb li cas hauv qab ntau qhov amplitudes thiab frequencies sib txawv:
- Kev rho tawm kev co qis-amplitude: txo qhov kev co uas kis tau thiab ua kom xis nyob dua
- Kev nqus zog nruab nrab / siab amplitude: tswj kev nruj thiab kev xav ntawm kev cuam tshuam
- Tus cwj pwm rov qab los: cuam tshuam rau "bouncy" kev xav thiab kev ruaj khov tom qab kev sib tsoo
- Kev ruaj khov ntev mus ntev: tiv thaiv kev txav mus los hauv qhov tawv nqaij thiab NVH teb tom qab laus
Yog tias koj cov hom phiaj NVH nruj heev, muab koj txoj kev sim lossis cov kab nkhaus (nyob ntawm qhov project). Peb tuaj yeem teeb tsa qib raws li koj nyiam qhov xis nyob thiab ruaj khov.

Kev Txhaj Tshuaj Molding & Kev Ruaj Ntseg ntawm Qhov Ntev
1) Qhuav
Cov dej noo muaj feem cuam tshuam rau qhov ruaj khov ntawm cov viscosity, kev ua kom zoo ntawm qhov chaw, thiab kev tswj qhov ntsws. Ziab kom qhuav kom huv si kom txo tau qhov warpage thiab qhov loj me.
2) Ruaj Khoov Sau & Ntim
Kev ntim khoom ruaj khov thiab kev ntim khoom kom txo tau kev ntxhov siab sab hauv thiab txhim kho qhov loj me uas rov ua dua tau. Kev tsim lub rooj vag thiab qhov cua nkag yog qhov tseem ceeb rau kev hloov pauv tuab mus rau nyias.
3) Tswj Kev Txias
Kev txias sib xws ua rau cov pwm ntsws sib xws. Qhov kub thiab txias sib xws pab tiv thaiv kev warpage thiab kev tawg ntawm qhov loj.
- Qhov rov ua dua qhov ntev:Muab koj lub qhov rais kam rau siab thiab qhov tseem ceeb; peb tuaj yeem muab qhov tseem ceeb rau kev tswj hwm qhov chaw (nyob ntawm qhov project).
- Kev ruaj khov mus sij hawm ntev:Paub meej tias qhov teeb tsa compression thiab qhov nruj ntawm qhov hloov pauv tom qab laus hauv qab koj qhov kev thauj khoom thiab qhov kub thiab txias.
- NVH tuning:Yog tias koj muaj cov kab teb rau lub hom phiaj lossis txoj kev sim, qhia nws kom txo cov voj voog xaiv.
Thov Cov Qauv / TDS
Rau cov bushings thiab dampers, txoj kev ceev tshaj plaws yog kom phim koj lub sijhawm thauj khoom thiab qhov yuav tsum tau ua kom deformation ntev, tom qab ntawd paub meej tias NVH xav li cas los ntawm koj txoj kev sim.
Tiv tauj peb kom tau txais daim ntawv teev npe luv luv thiab cov ntaub ntawv kev siv rau kev sim.
Yog xav tau ib daim ntawv qhia sai sai, xa mus rau:
- Hom khoom (bushing / damper / isolator), cov ntsiab lus geometry, thiab qhov loj me tseem ceeb
- Cov ntaub ntawv qhia txog kev thauj khoom: kev thauj khoom zoo li qub, qhov ntau thiab tsawg ntawm kev hloov pauv, thiab kev cia siab ntawm lub voj voog (yog paub)
- Kev nyiam qhov xis nyob piv rau qhov ruaj khov (NVH xav) thiab txoj kev sim (nyob ntawm qhov project)
- Qhov kub thiab txias thiab txhua yam kev txwv kev laus
- Kev txwv ntawm kev txhaj tshuaj molding: lub sijhawm kam rau siab, qhov tsos, lub sijhawm voj voog
