I-Dynamometer - ukulinganisa amandla emoto

26.05.2022 /

Isitendi seDynamometer - isikhungo esivumelayo izilinganiso zamandla ezimoto, izinjini zazo, izithuthuthu, amakariti, njll. Izitendi zingahlukaniswa ngokwemingcele emibili:

  • hlobo luni lwemishini okugxile kulo (i-auto, moto, injini ngokwehlukile)
  • uhlobo lokuma (umthwalo, ukungena ngaphakathi, kuhlanganisiwe)

Ake sihlolisise uhlobo ngalunye lwe-dynamometer.

Ukuma okungaphakathi

Ukuze kube lula, siphakamisa ukuthi kubhekwe ngokuqhubekayo ukuhola kusitandi semoto. Futhi-ke, isitendi sakhiwe ngohlaka, ekuboneni kokuqala okufana nokuphakamisa, kepha ngokuba khona kwezigubhu (uhlobo lwama-roller) ezindaweni lapho kufanele kube khona amasondo emoto. Uma besikhuluma ngesitimela sezithuthuthu, isigubhu esisodwa sanele lapho, ngoba isithuthuthu sinesondo elilodwa lokushayela. Emotweni edonsa ngamasondo angaphambili / angemuva, izigubhu ezimbili zanele, kahle kahle, uma kudonsa ngawo wonke amasondo, kuyadingeka ukuma okunezigubhu ezine.

Isitendi semitha yamandla sezithuthuthu

Imoto ibeka amasondo ezigubhini, njengomthetho, igiya eliphezulu livuliwe futhi amasondo emoto aqala ukuzulazula izigubhu. Ngokwemvelo, izigubhu zikhudlwana, kuba nzima ukuziphotha. Ngakho-ke, injini iguqula ijubane layo isuka kweliphansi iye kweliphezulu, zonke ezinye izilinganiso zenziwa yikhompyutha, ngokwesibonelo, ijubane lokujikeleza nesikhathi esichithwa ekuphothweni phezulu. Kusuka lapha kubalwa i-torque. Futhi vele kusuka mzuzu sithola amandla enjini imoto.

Manje mayelana nobuhle nobubi balolu hlobo:

Izinzuzo:

  • ubulula bokuklama, yingakho izindleko ezingabizi kakhulu;
  • amandla okubheka ukulahleka kwamandla ngenxa yokushayisana kokudluliswa;
  • amandla wokuhlola amapharamitha afana nekhwalithi yokwakha yenjini nezinga lokungena kwayo.

Umthengi:

  • akunakwenzeka ukuthola izinkomba ngemodi ye-static, i.e. ngejubane elingaguquguquki
  • amandla amakhulu, anciphisa ukunemba kwezilinganiso (lokhu kungenxa yokuthi ngamandla akhulayo, isikhathi sokuphotha izigubhu siyanda, ngakho-ke, isikhathi sokulinganisa siyancipha - ukunemba kuncipha)

Layisha ukuma

Isitendi sokulayisha ingxenye enkulu ifana ne-inertial, kepha inezinzuzo eziningi. Okokuqala, izigubhu zinesisindo esihlukile, futhi ukujikeleza kwemigqomo kwenziwa ngekhompyutha. Kungani kwenziwa lokhu? Ikakhulukazi ukuze wakhe ikhono lokugcina imoto nge-rpm engaguquki, nge-angle ethile yokuvulwa kwempintsha. Lokhu kuthuthukisa kakhulu ukunemba kokushuna kohlelo lokuthungela nokulethwa kukaphethiloli kulo lonke uhla lwe-rev.

Ukulinganiswa kwamandla emoto

Enye yezinzuzo eziphambili zesitendi sokulayisha kuba khona kwemoto yayo, engakwazi ukubopha amasondo, futhi okuphambene nalokho, kuyasheshisa (okungukuthi, sandisa isivinini senjini ngokudluliswa). Idivayisi elawulwayo ingaba ngogesi, i-hydraulic kanye ne-frictional. Le ndlela ilusizo kakhulu ekusetheni i-idle, coasting.

Okubi:

  • ukwakhiwa okuyinkimbinkimbi;
  • izindleko eziphezulu;
  • ubunzima bokulinganisa ukungqubuzana kokushayisana.

I-dynamometer ehlanganisiwe

Empeleni, iqoqa yonke imisebenzi yezinhlobo ezimbili ezedlule, ibe yisixazululo somhlaba wonke, kepha ngemali eningi.

Imibuzo nezimpendulo:

Iyini i-dynamometer? Lona umshini oklanyelwe ukubala i-torque namandla emoto. iphinde isetshenziselwe ukulungisa kahle injini.

Isebenza kanjani i-dynamometer? Kubekwe imoto kuyo. Ama-roller angaphansi kwamasondo ngokuzimela akhulisa umthwalo kumasondo okushayela kuze kube yilapho injini yomlilo yangaphakathi ifinyelela isivinini esicacisiwe (kuyilapho amasondo engasheshisi noma awabhuleki).
