TORSION ntawm lub voj voog shafts -- TORSION OF SHAFTS . Ib tug tswv cuab uas raug rau ob peb tus uas tsim kev sib hloov ntawm nws cov longitudinal axis yog hu ua twisting lub sij hawm ntawm Torsion . Vim Torque siv rau Ncej tus ncej tsim shear stress thiab shear strain nyob rau hauv cov ntaub ntawv.
Ua raws li qhov no hauv kev xav, dab tsi yog torsion ncej?
Kev xa hluav taws xob cov ncej - ntawm cov motors thiab gearboxes, piv txwv li - raug rau torque loads uas ua rau torsion , los yog twisting ntawm lub ncej txog nws axis. Cov torsion , los yog twist, induced thaum torque siv rau a ncej ua rau ib qho kev faib tawm ntawm kev ntxhov siab tshaj qhov ncej cheeb tsam hla ntu.
Ib sab saum toj no, dab tsi yog lub voj voos? Kev txhais ntawm ncig ncej . A ncej excavated li lub tog raj kheej. Cov ncig ncej muaj zog sib npaug ntawm txhua lub ntsiab lus; yooj yim rau pob zeb hauv ob sab phlu thiab tubbing, ob qho tib si tuaj yeem ua kom tsis muaj dej; thiab muaj qhov tsawg kawg nkaus tsis kam rau airflow.
Xav txog qhov no, dab tsi yog qhov cuam tshuam ntawm torsion nyob rau hauv voj voog shafts?
Torsion Ntawm Circular Shafts . Torsion txhais tau tias twisting ib tug structural tswv cuab thaum nws yog loaded los ntawm couplethas tsim rotation txog longitudinal axis. Kos npe rau convention ntawm lub zog tuaj yeem piav qhia los ntawm txoj cai ntiv tes xoo. Ib tug zoo lub zog yog nyob rau hauv uas muaj nruj nyhuv ntawm txiv ntseej ntawm lub bolt.
Torsion formula yog dab tsi?
General kev sib npaug torsion T = torque los yog twisting lub sij hawm, [N × m, lb × hauv] J = polar moment of inertia los yog polar thib ob lub sij hawm ntawm cheeb tsam txog ncej axis, [m4, hauv4] τ = shear stress at outer fiber, [Pa, psi] r = radius of the ncej, [m, in]

Dab tsi yog ib qho ntawm thawj kev lag luam cuam tshuam los ntawm kev lag luam kiv puag ncig?
Textiles yog qhov tseem ceeb ntawm kev lag luam ntawm Industrial Revolution nyob rau hauv cov nqe lus ntawm kev ua hauj lwm, tus nqi ntawm cov zis thiab peev peev. Kev lag luam textile kuj yog thawj zaug siv txoj kev tsim khoom niaj hnub no. Kev Lag Luam Kev Lag Luam tau pib hauv Great Britain, thiab ntau qhov kev tsim kho thev naus laus zis yog los ntawm British keeb kwm
Dab tsi yog txhais los ntawm ib puag ncig ntawm HRM?
Ib puag ncig ntawm HRM suav nrog tag nrho cov xwm txheej uas muaj kev coj tus cwj pwm (nrog rau lossis txhawb nqa) ntawm kev ua haujlwm ntawm HR department. Cov no yog - nom tswv-kev cai lij choj, kev lag luam, kab lis kev cai, thev naus laus zis, koom haum, kev coj noj coj ua thiab kev tsis sib haum xeeb, thiab, cov koom haum tshaj lij
Dab tsi yog qhov cuam tshuam ntawm kev tsheb loj heev ntawm ib puag ncig?
