Umothuko{0}}ukufunxa iRabha Bladders

Umothuko-efunxa irabha yesinyi ngokuqhelekileyo ibhekisa kwilungu lerabha njengeelastiki yangaphakathi, evalwe kwiqokobhe (elidla ngokuba yintsimbi yesilinda) kwaye ifunxa kwaye ithobe amandla okungcangcazela nge-elastic deformation yayo.

Umgaqo wokudambisa usekwe ikakhulu kwiipropati ezizodwa zerabha:

I-Elastic deformation ifunxa amandla:Xa uphantsi kwempembelelo yangaphandle okanye ukungcangcazela, umzimba werabha wangaphakathi uphantsi koxinzelelo, ukucheba, okanye ukuguqulwa kwe-torsion, ukuguqula amandla e-kinetic abe yi-elastic amandla erabha.

Iimpawu zokudambisa zidla amandla:Irabha yinto ebonakalayo ebonakalayo eyenza ukukhuhlana okunzulu kwangaphakathi phakathi kwamatyathanga ayo emolekyuli ngexesha lokuguqulwa okuphindaphindiweyo, iguqula amandla ayo amaninzi anokunwebeka (malunga ne-60% nangaphezulu) kumandla obushushu kwaye iwachithe emoyeni. Le nkqubo imanzi, eyona nto ingundoqo ekufunxeni okothusayo.

Ukukhutshwa kwamandla:Amandla aseleyo akhululwa kancinci ngendlela yokubuyisela i-elastic, ngaloo ndlela ephepha impembelelo eqinile.

Ngamafutshane, kufana nokubetha irabha engqindilili, ekumgangatho ophezulu ngamandla. Uninzi lwamandla akho 'atyiwa' luguquko kunye nokukhuhlana kwangaphakathi kwerabha, kunokuba uyibuyisele umva yonke.

Iifomu zoyilo lomothuko{0}}olufunxa irabha yangaphakathi liner ziyahluka ukuqhelana neendlela ezahlukeneyo zoxinzelelo kunye nokunciphisa indawo:
Uhlobo lwelayini:

• Ulwakhiwo: Olona hlobo luxhaphakileyo lufana nomkhono werabha, odla ngokuba nentsimbi engundoqo yentsimbi ngaphakathi kunye nomkhono wesinyithi ngaphandle, unomaleko werabha ovulzwe kwaye udityaniswe phakathi kwezi zibini.
• Umgaqo osebenzayo: Uxhomekeke ikakhulu kugutyulo lwe-chear kunye nokuguqulwa koxinzelelo lwerabha umaleko ukubonelela ngokufunxa ukothuka kunye nokuthintela.
• Isicelo: Ingalo yokulawula ukumiswa kweemoto, ukumiswa kwe-injini, intonga yokudibanisa ibha, njl njl.

Uhlobo lwebhloko/uhlobo olupakishwe:

• Ulwakhiwo: Yenziwe ngeebhloko ezininzi zerabha eziqinileyo okanye ezinomgongxo ezipakishwe okanye ezidityanisiweyo ukunika uguquko olukhulu kunye nomthwalo{0}}nomthamo wokuthwala.
• Umgaqo wokusebenza: Ikakhulu isekelwe kwi-deformation yoxinzelelo.
• Isicelo: Isiseko sezixhobo ezinkulu, imithombo encedisayo kwiibhogi zezithuthi zokuhamba ngololiwe, njl.

Uhlobo lwengalo ejijekileyo:

• Ulwakhiwo: Yenzelwe ngokukodwa ukumelana namaxesha obunzima.
• Isicelo: Ukumiswa kwe-injini ye-Automotive (i-injini yokuthintela ukujija), iihinge ezahlukeneyo.

I-advanteji:

• Ukudambisa okuphezulu: Ukusebenza kwayo okudaliweyo kugqwesile, okunokuthi kucinezele ngokufanelekileyo i-resonance amplitude kunye nokufunxa impembelelo ngaphandle kwesidingo se-damper eyongezelelweyo.
• Ubunzima obuthathu becala bunokuqulunqwa: Ngokutshintsha i-rubber formula, isakhiwo sangaphakathi, kunye nesimo sejometri, ukuqina kwayo kunye neempawu kwi-radial, axial, kunye ne-torsional directions inokwakheka ngokuzimeleyo.
• Akukho lungiso lufunekayo: Njengenxalenye yendibano evaliweyo, xa sele ifakiwe, ayifuni kugcinwa kulondolozo ngexesha lokuphila kwayo.
• Ukugqunywa kombane: Irabha sisigqubuthelo esilungileyo esinokuthi sithintele ukubunjwa kweesekethe zombane (i-electrocorrosion) phakathi kwamacandelo esinyithi.
• Iindleko eziphezulu-ukusebenza kakuhle: Kwiimfuno zomothuko omncinci naphakathi{1}}nobungakanani obuphakathi, iyonga kwaye ixinene kuneenkqubo zomoya.

imida:

• Higher natural frequency: Compared to air springs, air springs have higher stiffness and typically have a higher natural frequency (>5Hz), kodwa ukusebenza kwabo ekwahluleni-ukungcangcazela okuncinci okuphantsi akulunganga njengemithombo yomoya.
• Ukuguga kunye nokuguga: Irabha ingena kwi-creep (i-permanent deformation) phantsi kwe{0}}imithwalo yexesha elide, kwaye iimpawu zayo ziyaguga ngokuthe ngcembe ngenxa yefuthe lobushushu, i-ozone, igrisi, kunye nemitha ye-ultraviolet.
• Ukungaguquguquki kokusebenza: Ukusebenza kwayo kuchaphazeleka kakhulu kubushushu, kuba nzima kumaqondo obushushu aphantsi kwaye kuthambile kumaqondo obushushu aphezulu, kunye neempawu zayo zokudambisa nazo ziyatshintsha.

Umothuko-efunxa irabha yesinyi lusebenza kakuhle ngokoqoqosho kwaye lusetyenziswa ngokubanzi umothuko{1}}ilungu elifunxayo elisebenza ngokusekwe kwiimpawu zemathiriyeli ngokwayo. Isebenzisa amandla ngokusebenzisa i-viscoelasticity yerabha kwaye iye yaba "idibeneyo" kunye ne "cushion" eyimfuneko kumatshini wanamhlanje kunye nokuthutha ngenxa yesakhiwo sayo esilula kunye nokusebenza okuthembekileyo. Xa imfuno yakho kukucinezela i-mid to high frequency vibrations, ukufunxa iimpembelelo, kwaye kungafuneki uhlengahlengiso rhoqo, indibano ye-shock absorber kunye ne-rubber yangaphakathi liner idla ngokuba sisisombululo esithandwayo.

Iifayile ezishisayo: ukothuka-ukufunxa izinyi zerabha, ukothuka kweTshayina{1}}abavelisi berabha efunxa irabha, ababoneleli, umzi-mveliso
