Kev txhaj tshuaj peening tsis tshem tawm yam khoom. Cov txheej txheem tsuas yog ua rau me me craters nyob rau hauv nyias txheej txheej ntawm cov khoom. Raws li twb tau hais lawm cov txheej txheem no txhim kho lub zog thiab lub neej ntev ntawm cov khoom.
Puas tua peening ntxiv cov khoom?
Los ntawm muab cov khoom nyob rau hauv compressive kev nyuaj siab, tua peening tiv thaiv xws li tawg los ntawm propagating. … Yas deformation induces ib tug residual compressive kev nyuaj siab nyob rau hauv ib tug peened nto, nrog rau tensile kev nyuaj siab nyob rau hauv sab hauv.
Lub hom phiaj ntawm kev txhaj tshuaj peening yog dab tsi?
Kev txhaj tshuaj peening yog txheej txheem ua haujlwm txias siv txhawm rau muab cov kev ntxhov siab seem nyob rau ntawm qhov chaw ntawm cov khoom siv, uas ua rau cov khoom hloov kho. Cov txheej txheem txhaj tshuaj yog siv los ntxiv lub zog thiab txo qhov kev ntxhov siab ntawm cov khoom.
Puas txhaj tshuaj peening txhim kho nto tiav?
Cov txiaj ntsig tau pom tias cov txiaj ntsig ntawm kev txhaj tshuaj peening ntawm cov qauv yog qhov muaj zog heev thiab ua rau muaj qhov nce ntxiv ntawm qhov roughness; sib txawv milling tsis ua rau qhov sib txawv loj ntawm qhov chaw roughness R a los ntawm 0.184 mus rau 1.4 hli; nto roughness tom qab txhaj tshuaj peening nyob rau hauv tib yam mob yog ze heev. …
peening ua li cas rau hlau?
Peening yog txheej txheem ntawm kev ua haujlwm ntawm cov hlau saum npoo los txhim kho nws cov khoom siv, feem ntau yog los ntawm kev siv tshuab, xws li rauj tshuab, los ntawm blasting nrog txhaj tshuaj (shot peening) lossis blasts. ntawm lub teeb beams nroglaser npav. Peening yog ib txwm ua haujlwm txias, nrog laser peening yog qhov tshwj xeeb.
