Hauv kev tsim khoom ntawm automotivehydraulic nres qhov chaw, cov khoom lag luam ntseeg tau ncaj qha los ntawm cov ntaub ntawv - tsav kev sim siab. PebSiab -Tsuas Kub Kub Endurance Test Chamberyog ib qho chaw tseem ceeb uas tau mob siab rau qhov tseem ceeb ntawm cov txheej txheem kev lees paub zoo, ua kom txhua tustswv cylinder, lub tog raj kheej, thiab ABS hydraulic tswj chav ua tau raws li lub neej nruj heev - kev ua haujlwm yuav tsum tau ua.
Test Objective thiab Methodology
Lub luag haujlwm tseem ceeb ntawm lub chamber tshwj xeeb no yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kev laus hauv qabua ke thermalthiabmechanical kev nyuaj siab. Cov txheej txheem no ntsuas lawvkev ua haujlwm ncaj nceesthiabfoob durabilitylos ntawm simulating xyoo ntawm kev ua hauj lwm teb nyob rau hauv ib tug tswj lub sij hawm nyob rau hauv lub laboratory.
Kev ntsuam xyuas yog ua nyob rau hauv ob hom thawj, muaj kev cuam tshuam tiag tiag - ntiaj teb kev siv:
- Standard Pressure Cycle Endurance:Hom no ntsuas cov khoom nyob rau hauv kev txhawb nqa siab loading, simulating ib txwm braking daim ntawv thov nyob rau lub sij hawm ntev.
- ABS Siab Modulation Endurance:Qhov kev ntsuam xyuas hnyav dua no rov ua dua qhov nrawm, siab - zaus hloov pauv hloov thaum lub sij hawm Anti-lock Braking System (ABS) lossis Electronic Stability Program (ESP) ua kom muaj zog, ua rau nyuaj rau cov lus teb thiab kev sib khi ruaj khov.
Precision-Controlled Testing Systems
Lub chamber qhov ua tau zoo yog nyob ntawm kev sib koom ua ke ntawm peb lub tshuab synchronized:
Climatic Stress Generation:
Lub kaw lus tsim thiab tswj xyuas qhov kub thiab txias ib puag ncig, xws li qhov kub siab heev mus txog +120℃mus rau qhov qis ntawm -40 degree, ua raws li cov qauv qhia tshwj xeeb.
Hydraulic Load Application:
Lub servo- tswj hydraulic system kom raug siv qhov programmable siab profiles. Nws muab cov qib siab tshwj xeeb, suav nrog lub voj voog, thiab cov zaus uas yuav tsum tau ua los ntawm cov txheej txheem kuaj rau ob qho tib si qauv thiab ABS hom kev caij tsheb kauj vab.
Automated Kev Ua Haujlwm thiab Saib Xyuas:
Tag nrho cov txheej txheem yog tswj los ntawm lub hauv paus tswj. Nws automates xeem sequencing, ua hauj lwm lub actuator uas simulates pedal input, thiab tsis tu ncua teev cov tseem ceeb tsis xws li kub, siab, lub voj voog suav, thiab cov xwm txheej rau tag nrho traceability.
Ua raws li cov qauv kev xeem ntawv tso cai
Peb cov kev ntsuas ntsuas tau txhais los ntawm cov qauv kev lag luam uas lees paub, ua kom muaj kev cuam tshuam thoob ntiaj teb thiab kev ua haujlwm nruj. Peb cov txheej txheem ua ke nrog cov ntu tseem ceeb ntawmQC/T 311-2018thiabJIS D 2603: 2005, uas qhia txog qhov tseem ceeb ntawm qhov pib rau kev siv cov khoom siv.
Piv txwv li, nyob rau hauv cov qauv no, ib feem yuav tsum tau ua kom tiav125,000 lub voj voog siab ntawm qhov kub siab, ua raws li45,000 cycles ntawm -40 degree, thiab ib qho ntxiv80,000 cycles ntawm ambient kub. Hauv ABS simulation hom, cov khoom siv yuav tsum tiv taus ntau txhiab tus aggressive siab - mus rau - tsis tshua muaj kev hloov pauv. Lub chamber ua tiav cov kev xav tau niaj hnub no ntseeg tau, ua tau zoo dua10,000 xeem cycles txhua hnubkom xa cov ntaub ntawv lees paub tseeb hauv lub sijhawm ua haujlwm.
Qhov Kev Tshawb Fawb Kawg: Seal Integrity Hold Test
Tom qab qhov kev ntsuam xyuas kev caij tsheb kauj vab dynamic, qhov kev ntsuam xyuas tseem ceeb tau ua tiav. Txhua yam khoom ua tiav qhov kawghydraulic foob kev ruaj ntseg pov thawj. Nws yog pressurized rau 100% thiab tom qab ntawd 130% ntawm nws qhov siab tshaj plaws ua haujlwm siab thiab tuav. Siv lub siab - kev soj ntsuam rhiab heev, peb paub tseeb tias txhua qhov kev puas siab puas ntsws tseem nyob hauv qhov txwv nruj tshwj xeeb (tsawg li0.1 MPa siab) tso cai los ntawm cov qauv. Cov kauj ruam kawg no yog qhov hla dhau / tsis ua haujlwm rau txhua chav.
Peb cog lus rau kev ua tau zoo
Qhov kev ntsuas kev ntsuas no yog lub lim dej kom zoo. Txhua yam khoom siv hauv cov khoom tsim tawm yog raug rau qhov kev lees paub no. Ib chav tsev twg uas tsis ua raws li txhua qhov kev ua tau zoo-txawm yog thaum lub sijhawm caij tsheb kauj vab lossis qhov kev xeem tuav zaum kawg- yogtam sim ntawd txheeb xyuas thiab cais lub cevlos ntawm cov khoom muag pom zoo.
Qhov kev xyaum nonruj tsis- ua raws li cov khoom sib caisyog qhov tseem ceeb rau peb txoj kev qhuab qhia ua haujlwm. Nws tiv thaiv txhua qhov sub- tus qauv ib feem los ntawm kev nce qib thiab ua rau muaj cov ncauj lus kom ntxaws txog engineering los daws qhov laj thawj. Rau peb cov neeg siv khoom, nws muab kev lees paub tias txhua qhov khoom xa tuaj tau ua pov thawj ntawm nws tus kheej kom ruaj khov raws li qhov xav tau tshaj plaws simulated.
Xaus
Peb Lub Siab -Tshav Kub Kub Qhov Ntsuas Ntsuas Kub yog qhov kev nqis peev tseem ceeb hauv kev ntsuas qhov zoo. Los ntawm kev tswj hwm tus txheej txheem kuaj tau los ntawmcov qauv thoob ntiaj tebthiab txuas nrog nws nrog txoj cai tsis sib haum xeeb, peb hloov qhov yuav tsum tau muaj kev nyab xeeb nres rau hauv cov khoom siv tau, txheeb xyuas qhov tseeb. Nws yog los ntawm cov txheej txheem nruj heev uas peb ua kom ntseeg taukev ntseeg tauntawm peb hydraulicnres qhov chaw, txhawb kev nyab xeeb tsheb hauv txhua qhov chaw ua haujlwm.
