Raws li cov txheej txheem tseem ceeb hauv kev tshawb fawb txog niaj hnub no, kev tsim khoom lag luam, thiab kev kawm, cov rooj tog zaum sim muab cov qauv tsim, tswj tau qhov chaw ua haujlwm rau ntau yam kev sim, kev sim, thiab kev ua haujlwm raug cai. Los ntawm kev sib koom ua ke ntawm ntau yam txuj ci xws li tshuab, hluav taws xob, automation, thiab kev tau txais cov ntaub ntawv, cov rooj tog zaum simulate tiag -lub ntiaj teb kev ua haujlwm thiab ntsuas ntau npaum li cas cov khoom ua tau zoo, kev ntseeg siab, lossis kev tshawb fawb theories. Lawv yog cov cuab yeej tseem ceeb rau kev txhawb nqa technology innovation thiab engineering xyaum.
I. Basic Cheebtsam thiab Classifications of Test Benches
Lub cev qauv ntawm lub rooj ntev zaum xeem feem ntau muaj plaub yam: lub platform load, functional modules, ib tug tswj system, thiab auxiliary chaw. Lub platform thauj khoom ua haujlwm raws li lub hauv paus txheej txheem thiab yuav tsum ua tau raws li kev ruaj ntseg thiab kev thauj khoom. Cov qauv ua haujlwm tau raug kho raws li lub hom phiaj kev sim, xws li cov khoom siv thauj khoom hauv kev sim tshuab, ntsuas kub thiab av noo hauv kev sim ib puag ncig, thiab cov teeb liab generators hauv kev sim hluav taws xob. Lub kaw lus tswj tswj kev ua haujlwm ntawm txhua qhov module, suav nrog cov sensors, actuators, thiab tib neeg-tshuab interfaces. Cov chaw pabcuam suav nrog cov tshuab hluav taws xob, cov khoom siv kev nyab xeeb, thiab khaws cov ntaub ntawv.
Raws li cov cheeb tsam hauv daim ntawv thov, cov rooj zaum xeem tuaj yeem muab faib ua peb pawg: kev tshawb fawb txog kev tshawb fawb, kev tshawb xyuas engineering, thiab kev qhia ua qauv qhia. Cov kev tshawb fawb tshawb fawb cov rooj zaum tsom mus rau kev tshawb nrhiav cov ntsiab lus tsis paub, xws li cov khoom siv micro- cov khoom siv kuaj lub rooj zaum thiab cov dej dynamics simulation lub rooj zaum, thiab feem ntau yog nruab nrog siab - cov cuab yeej precision thiab kho software. Engineering pov thawj xeem cov rooj zaum, xws li automotive engine durability test beches thiab avionics compatibility test benches, pab lub voj voog kev loj hlob ntawm cov khoom thiab hais txog qhov sib xws nrog cov kev ua haujlwm tiag tiag. Kev kawm ua qauv qhia kev xeem cov rooj zaum, feem ntau pom nyob rau hauv tsev kawm ntawv lub chaw soj nstuam, ua qhov tseem ceeb ntawm kev nkag siab zoo thiab kev nyab xeeb ntawm kev ua haujlwm, pab cov tub ntxhais kawm nkag siab txog kev siv engineering ntawm kev paub theoretical.
II. Cov yam ntxwv tseem ceeb thiab kev loj hlob Trends
Kev hloov kho dua tshiab hauv cov rooj zaum sim niaj hnub no feem ntau cuam tshuam hauv peb thaj chaw: kev txawj ntse, kev hloov pauv, thiab siab precision. Kev txawj ntse vam khom rau hauv Internet ntawm Yam (IoT) thiab ntug kev siv thev naus laus zis. Distributed sensors yog siv los sau ntau- cov ntaub ntawv qhov ntev (xws li vibration zaus, siab hloov pauv, thiab kub gradients) nyob rau lub sijhawm, thiab tshuab kev kawm algorithms yog siv los soj ntsuam cov txiaj ntsig kev sim thiab kwv yees qhov yuam kev. Modular tsim tso cai rau cov neeg siv los hloov kho cov haujlwm ua haujlwm raws li lawv cov kev xav tau, xws li hloov cov khoom siv hydraulic thauj khoom nrog hluav taws xob servo modules lossis nthuav cov kev sib txuas lus wireless sib txuas, txhim kho cov khoom siv rov ua dua thiab hloov tau. High precision yog reflected nyob rau hauv sensor daws teeb meem tshaj li micron theem (xws li nano-tso sensors) thiab tswj lub sij hawm teb lub sij hawm mus txog milliseconds, kom ntseeg tau thiab repeatability ntawm kev sim cov ntaub ntawv.
Tam sim no, cov rooj zaum sim tau nrawm dua lawv txoj kev hloov pauv mus rau digitalization thiab kev txhim kho ntsuab. Kev taw qhia ntawm cov cuab yeej digital ntxaib ua rau muaj kev sib koom ua ke ntawm kev sim virtual thiab lub cev. Los ntawm kev tsim cov qauv digital ntawm cov khoom sim, cov phiaj xwm kev sim tuaj yeem rov hais dua thiab cov kev ntsuas tsis zoo hauv ib puag ncig virtual, thiab cov txiaj ntsig tuaj yeem raug txheeb xyuas ntawm lub rooj zaum ntawm lub cev, ua rau lub voj voog R & D luv. Tsis tas li ntawd, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig yog tsav kev siv qis- cov khoom siv hluav taws xob (xws li hloov pauv tau- lub cev muaj zog thiab LED teeb pom kev zoo) thiab cov khoom siv hluav taws xob rov qab pov tseg hauv cov rooj zaum sim, txo cov kev siv hluav taws xob thiab cov pa roj carbon monoxide thaum ua haujlwm.
III. Cov xwm txheej ntawm daim ntawv thov thiab tus nqi ua piv txwv
Hauv kev lag luam kev lag luam, cov rooj tog zaum sim yog qhov tseem ceeb ntawm kev tswj cov khoom zoo. Piv txwv li, lub zog tshiab lub tsheb roj teeb pob yuav tsum muaj kev vibration xeem lub rooj zaum los sim ua kom muaj kev ncaj ncees nyob rau hauv txoj kev tsis sib haum xeeb, thaum siab - thiab qis - qhov ntsuas kub ntawm lub rooj zaum yog siv los txheeb xyuas cov tshuaj lom neeg ruaj khov hauv huab cua huab cua. Hauv kev lag luam aerospace, kev tswj hwm lub dav hlau yuav tsum tau dhau qhov kev sim siab ntawm kev hloov tus cwj pwm qhov tseeb ntawm rau -degree- ntawm - txoj kev ywj pheej ntawm kev sim cov rooj zaum. Cov tsev kawm tshawb fawb siv cov rooj zaum sim los ua kev txiav- kev tshawb fawb thev naus laus zis. Piv txwv li, cov khoom siv quantum xav tau ultra{10}} qis- qhov ntsuas kub ntawm lub tshuab nqus tsev ntsuas ntsuas ntsuas ntsuas quantum entanglement ntawm microscopic particles, thaum biomedical engineering cia siab rau cov kab lis kev cai ntawm tes los soj ntsuam cov biocompatibility ntawm cov ntaub so ntswg engineering.
Hauv kev kawm txuj ci, cov rooj sib tw xeem ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev ua tau zoo. Los ntawm kev khiav hauj lwm cov cuab yeej siv yooj yim xws li lub hauv paus ntsiab lus ua qauv qhia lub rooj zaum thiab Circuit Court tsim lub rooj zaum, cov tub ntxhais kawm tuaj yeem txhais cov qauv theoretical paub daws teeb rau hauv kev ua vaj tse pob zeb. Piv txwv li, lawv tuaj yeem soj ntsuam cov kev hloov pauv hauv kev ntxhov siab los ntawm kev kho cov ntsiab lus txhawb nqa ntawm cov qauv nqaj, lossis txheeb xyuas cov txiaj ntsig zoo ntawm cov cim ntawm ntau zaus siv oscilloscope. Qhov "kev kawm los ntawm kev ua" tus qauv no tsis yog tsuas yog txhim kho cov tub ntxhais kawm cov kev txawj ntse tab sis kuj txhawb lawv txoj kev xav tshiab.
Xaus
Raws li tus choj ntawm kev tshawb xav thiab kev xyaum, thev naus laus zis kev nce qib ntawm kev sim cov rooj zaum ncaj qha cuam tshuam rau kev ua tau zoo thiab zoo ntawm kev tshawb fawb thiab thev naus laus zis. Nrog rau kev sib sib zog nqus ntawm kev txawj ntse, cov ntaub ntawv tshiab, thiab kev tsim cov thev naus laus zis, cov rooj zaum zaum tom ntej yuav txhim kho ntxiv mus rau kev sib koom ua ke ntau, kev sib koom tes hauv thaj chaw deb, thiab kev tswj xyuas tag nrho lub neej, muab kev txhawb zog rau kev tshawb fawb thiab thev naus laus zis thoob ntiaj teb thiab kev txhim kho kev lag luam.
