Autofrettage Applications Cov txheej txheem feem ntau yog siv rau hauv kev tsim khoom siab-siab twj cylinders, roj txhaj tshuab rau diesel xyaw thiab warships thiab tank phom chim. Ib yam li ntawd, cov txheej txheem kuj tseem siv rau hauv kev nthuav dav ntawm tubular Cheebtsam hauv cov roj thiab roj qhov dej.
Daim ntawv thov ntawm autofrettage yog dab tsi?
Cov txheej txheem autofrettage yog dav siv hauv ntau yam lag luam. Txhawm rau nce kev ua haujlwm siab rau kev lag luam siab, tsheb, aerospace thiab kev tiv thaiv tshuab, daim ntawv thov txheej txheem autofrettage yuav tsum tau txhawm rau txhim kho lub neej qaug zog. Autofrettage kuj tseem siv los ntxiv dag zog rau cov phom phom.
Vim li cas cov txheej txheem autofrettage siv hauv cov hlab ntsha siab?
Cov txheej txheem autofrettage feem ntau yog siv los tsim cov compressive tangential residual stresses nyob ze ntawm lub bore, uas txhim kho lub neej qaug zog ntawm lub nkoj siab.
Dab tsi yog autofrettage hauv cov hlab ntsha siab?
Autofrettage yog cov txheej txheem hlau txias ua cov txheej txheem uas lub nkoj siab tau raug lub siab loj, ua rau cov khoom sab hauv ntawm cov khoom tawm los ntawm plastically, ua rau sab hauv compressive residual stresses ib zaug lub siab tso tawm.
autofrettage txhais li cas?
: daim ntawv thov ntawm lub siab sab hauv mus rau lub bore ntawm ib rab phom hnyav li yuav deform lub puab txheej ntawm hlau dhau qhov elastic txwv uasyuav tau mus txog ntawm qhov tawg ntawm tej nqi yuav siv tom qab nyob rau hauv rab phom.
