IiBushings kunye neeDampers zeTPU Compound | Ithwala Umthwalo Ophezulu, Ayikwazi Ukurhawuzelelwa
IiBushings kunye neeDampers zeTPU Compound
Iikhompawundi zeTPU ezenzelweiibhushi zokumiswa kweemoto, izinto zokudambisakunyeiindawo zokwahlulwa kokungcangcazela,
apho ukusebenza kuxhomekeke khonaukufunxwa kwamandla, ukubuyela umva okulawulwayo, iseti yoxinzelelo oluphantsikunyeuzinzo lwemilo yexesha elide.
Eli phepha ligxile kwindlela yokubeka izixhobo zeTPUI-NVH(ingxolo, ukungcangcazela, intuthuzelo), ukuqina kokudinwa, kunye nolawulo lobukhulu bokubumba ngenaliti.
Kwizinto ezisetyenziswa kwiibhushi kunye nee-dampers, izinto "ezilungileyo" azipheleli nje ekubeni namandla aphezulu. Lulungelelwano phakathi
ukomelela(amandla abuyayo),ukudambisa(ukufunxa amandla), kunyeulawulo lweseti yokucinezelwa(ebambe imilo phantsi komthwalo).
Olu lungelelwaniso luchaphazela ngokuthe ngqoUvakalelo lwe-NVH, uzinzo lokukhwela, kunye nobomi benkonzo.

Izicelo eziqhelekileyo
- Iibhushi ezixhonyiweyo: iingalo zolawulo, izinto ezizinzisayo, iindawo zojongano lwesakhelo esingaphantsi (ezixhomekeke kwiprojekthi)
- Izinto ezidambisa umswakama: izitophu zokubuyela umva, iibhloko ze-buffer, iindawo zenkxaso ye-elastic apho ukuguquguquka kwenzeka rhoqo
- Izinto ezihlukanisa ukungcangcazela: izakhiwo zokugquma okanye zokwahlukanisa apho intuthuzelo kunye nolawulo lwengxolo zibalulekile
- Izixhobo ze-elastomer zokunxiba/zokuthintaapho ukungqubana, ukudinwa, kunye nokuzinza kokuguquguquka kufuneka kulungelelaniswe
Ukukhetha Amanqaku Akhawulezileyo (Uluhlu Olufutshane)
Khetha u-“Comfort NVH” xa
- Ukwahlulwa kokungcangcazela kunye nentuthuzelo yokuhamba zezona zinto ziphambili ekujoliswe kuzo
- Ufuna impendulo ethambileyo kunye nokunciphisa uburhabaxa
- Uluhlu lomthwalo ophakathi kunye notshintsho olunesimo esizinzileyo sokubuyela umva
Khetha u-“Load & Stability” xa
- Ulawulo lweseti yoxinzelelo lubalulekile xa umthwalo wexesha elide ungashukumi
- Ubomi benkonzo yokuqhuba i-drive yokugcina iimilo kunye nozinzo olunemilinganiselo
- Uxinzelelo oluphezulu lokuguquguquka kunye nolawulo oluqinileyo lokubuyela umva luyadingeka
Qaphela: Indawo yokugqibela ixhomekeke kwiprofayili yomthwalo (i-static vs i-dynamic), impendulo yokuqina kwethagethi, uluhlu lobushushu, kunye neemfuno zokulungisa i-NVH.
Ukusebenza kwe-NVH: Okubalulekileyo ekusebenzeni
I-NVH ayilonani linye. Kwiindawo ze-elastomer, ukuziphatha kwe-NVH kuvela kwindlela izinto ezisabela ngayo phantsi kwe-amplitudes kunye nee-frequency ezahlukeneyo:
- Ukwahlulwa kokungcangcazela okuphantsi: kunciphisa ukungcangcazela okusasazekayo kwaye kuphucula intuthuzelo
- Ukufunxwa kwamandla aphakathi/aphezulu: ilawula uburhabaxa kunye nemvakalelo yempembelelo
- Ukuziphatha okujikayo: ichaphazela imvakalelo "yokutsiba" kunye nokuzinza emva kweziganeko zokucinezelwa
- Uzinzo lwemilo yexesha elide: ithintela ukuguguleka kokuqina kunye nokusabela kwe-NVH emva kokwaluphala
Ukuba iithagethi zakho ze-NVH zingqongqo, nika indlela yakho yokuvavanya okanye i-target curve (ixhomekeke kwiprojekthi). Singalungelelanisa indawo yokubeka inqanaba ngokuhambelana nokukhetha kwakho okukhululekileyo kunye nokuzinza.
Iindlela Eziqhelekileyo Zokusilela (Isizathu → Ukulungiswa)
Sebenzisa itheyibhile yokuxilonga engezantsi ukunciphisa ii-trial loops kwaye uchonge ukuba yeyiphi ibhalansi yepropathi efuna ukulungiswa:
| Imo Yokusilela | Eyona nto ixhaphakileyo | Ulungiso olucetyiswayo |
|---|---|---|
| Ukuguquguquka okungapheliyo / ukuwohloka emva komthwalo omde | Uxinzelelo lubekwe phezulu kakhulu; ibhalansi yefomyula inceda ukubuyela umva kodwa ilahlekelwa kukugcinwa kwesimo | Yiya kwindawo esezantsi yokubeka uxinzelelo; qinisekisa iseti yoxinzelelo kunye nokushukuma okulinganayo emva kokwaluphala |
| Imvakalelo yokujika "ebhityileyo kakhulu" | Ukuqina okuphezulu kakhulu ukuba kungafumaneki nto ifanelekileyo; ukufunxwa kwamandla okwaneleyo kwimpendulo eguqukayo | Lungisa ibhalansi ye-rebound/damping; khetha indawo ye-comfort-NVH; qinisekisa kwiimvavanyo ze-dynamic ze-part-level |
| Impembelelo embi / ukungazibandakanyi kakuhle | Inkqubo iqinile kakhulu xa incinci okanye ayilungiselelwanga uluhlu lokungcangcazela | Tshintshela kusapho oluthambileyo okanye olugxile ekuzihlukaniseni; bonelela ngesithuba sokutshintsha umthwalo ukuze ufanise |
| Ukuqhekeka phantsi kokuguqulwa kwe-cyclic | Umda wokudinwa awanele; uxinzelelo oluphezulu kwiindawo zokutshintsha kwejometri okanye zokubopha | Yandisa indawo ekwaziyo ukumelana nokudinwa; phucula utshintsho lwejometri; qinisekisa ukudinwa kunye nokukrazula iindawo ezibunjiweyo |
| Ubungakanani bokushukuma / i-warpage emva kokubumba | Ukupholisa kunye nokuncipha akuzinzanga; ifestile yokufuma okanye yokucubungula incinci kakhulu | Yomisa kakuhle; zinzisa ubushushu bokunyibilika kunye nokupholisa; yenza ngcono isango/ukupakisha; cinga ngephakheji yokulawula ukuncitshiswa |
Amabanga aqhelekileyo kunye nokuBekwa kwindawo ethile
| Usapho lweBanga | Ukuqina | Ukugxila kuYilo | Ukusetyenziswa Okuqhelekileyo |
|---|---|---|---|
| I-TPU-AUTO BSH Comfort NVH | 80A–95A | Ukufunxwa kwamandla + ukubuyela umva okuthambileyo ukuze uzive ukhululekile kwi-NVH (kuxhomekeke kwiprojekthi) | Iindawo zokwahlukanisa ukungcangcazela kunye nezihlahla ezibekwe kwindawo ekhululekileyo apho ukunciphisa uburhabaxa kubalulekile khona |
| Umthwalo kunye nozinzo lwe-TPU-AUTO BSH | 90A–65D | Ulawulo lweseti yoxinzelelo + uzinzo lwe-deformation yexesha elide phantsi komthwalo | Iibhushi ezithwala umthwalo kunye nezinto ezidambisayo ezifuna ubungakanani obuzinzileyo kunye nempendulo ehambelanayo ngokuhamba kwexesha |
Qaphela: Ubulukhuni obuchanekileyo kunye nokukhetha iphakheji kufuneka kuqinisekiswe yiprofayili yomthwalo, impendulo yokuqina kwethagethi, kunye neemfuno zokunyamezelana ngobukhulu.
Ukubumba ngenaliti kunye nozinzo olunemilinganiselo
1) Yomile
Ukufuma kuchaphazela uzinzo lwe-viscosity, ukuthembeka komphezulu, kunye nolawulo lokuncitshiswa. Yomisa kakuhle ukuze kuncitshiswe ukugoba kunye nokushukuma kobukhulu.
2) Zinzisa ukugcwalisa kunye nokupakisha
Ukuzaliswa okuzinzileyo kunye nokupakisha kunciphisa uxinzelelo lwangaphakathi kwaye kuphucula ukuphindaphindwa kobukhulu. Uyilo lwesango kunye nokuvula umoya kubalulekile kwiinguqu ezinkulu ukuya ezincinci.
3) Ulawulo lokuPholisa
Ukuqina kokupholisa kunciphisa ukufana. Ubushushu obungaguqukiyo bokubumba kunye nexesha lokupholisa kunceda ukuthintela ukuqhekeka kunye nokusabalalisa ubukhulu.
- Ukuphindaphinda okunemilinganiselo:Nika ithuba lakho lokunyamezelana kunye nobukhulu obubalulekileyo; singabeka phambili indawo yokulawula ukuncipha (kuxhomekeke kwiprojekthi).
- Uzinzo lwexesha elide:Qinisekisa iseti yokucinezelwa kunye nokuqina kwayo emva kokwaluphala phantsi komthwalo wakho oqhelekileyo kunye nobushushu.
- Ukulungiswa kwe-NVH:Ukuba une-target response curve okanye indlela yovavanyo, yabelana ngayo ukuze unciphise ii-select loops.
Cela iisampuli / i-TDS
Kwi-bushings kunye ne-dampers, eyona ndlela ikhawulezayo kukuhambelana nefestile yakho yokutshintsha umthwalo kunye neemfuno zokuguquguquka kwexesha elide, uze uqinisekise ukuvakalelwa kwe-NVH ngendlela yakho yovavanyo.
