Ib qho, kev ua
Die - casting technology plays a crucial role in modern industrial production and is widely applied in fields like automotive, military, aerospace, and medical industries, with the automotive industry being particularly prominent. The main shell of the rear - drive electrical control box in new energy vehicles is a key component with special structure and performance requirements, making it a focal point in die - casting process research. This article combines theoretical kev loj hlob thiab cov txheej txheem txhim kho kom nkag siab txog kev tuag - casting txheej txheem hluav taws xob lub plhaub ....
Ob, lub plhaub loj cov qauv thiab kev xav tau
Lub plhaub tseem ceeb ntawm lub thawv hluav taws xob yog qhov ua kom zoo nkauj - qhov loj ntawm 225 hli × 289 hli thiab qhov hnyav ntawm 1 {{5 1g.
Lub casting muaj tag nrho phab ntsa tuab ntawm kwv yees li 3mm, nrog qee cov chaw cua txias rau lub zog thiab hnav -}}
Qhov yuav tsum tau tua - chaniver rau saum npoo rougness thiab kev nyuaj siab - corrosion -} Cov neeg yuav tsum pom cov kab tawg, roj, tso rau tus neeg sawv cev, lossis oxidation; qhov tsis zoo - qhov chaw dawb tseem ceeb; burrs nyob rau hauv kev txwv tsis pub tshaj; thiab to to - Dawb tej kab noj hniav thiab dej nyob hauv teeb tsa pressures . cov kev xav tau siab los tuag - casting qhov tseeb.
Peb, kev sib ntaus thiab khiav kev tsim qauv thiab sim sim
Suav simulation tseem ceeb heev rau kev txhim kho cov khoom zoo thiab kev ua kom zoo, txo cov khoom lag luam thiab txhim kho cov khoom lag luam zoo .
(a) kev sib ntaus thiab khiav kev tsim qauv
Rau cov complex - rau - nruab nrab - qhov loj me kev coj ua rau cov khoom siv tsis ntev los ntawm cov khoom lag luam rau cov khoom lag luam rau cov khoom lag luam kom zoo dua thiab xau dej Kev Tiv Thaiv Kev Tiv Thaiv . ob sab txuas ntxiv rau qhov kawg thiab cov khoom siv tsis zoo
(b) Kev Tshawb Xyuas pes tsawg
Simulation software yog siv los tshuaj xyuas cov kev sib nrig ua ntej thiab khiav system .
1.} Txhij Txhuas Ua Kua
