MIL-STD-810H yog ib txoj hauv kev kuaj tus qauv uas yog ua haujlwm los ntawm cov tub rog thiab lwm lub koom haum los ntsuas qhov ruggedness thiab durability ntawm cov cuab yeej nyob rau hauv ib puag ncig hnyav. Txoj kev sim no muaj ntau qhov kev sim thiab kev sim teb uas simulate ntau yam kev nyab xeeb, kev siv tshuab, thiab hluav taws xob kev ntxhov siab thiab cov kab mob uas cov cuab yeej yuav ntsib thaum nws lub neej.
Cov ntawv thov tseem ceeb ntawm MIL-STD-810H kuaj suav nrog cov khoom siv tub rog thiab kev tiv thaiv, cov khoom siv dav hlau, cov khoom siv tsheb, thiab cov khoom siv hluav taws xob, thiab lwm yam. Txoj kev sim no tshwj xeeb yog qhov tseem ceeb hauv kev ntsuas qhov ua tau zoo ntawm cov khoom siv hluav taws xob, xws li smartphones thiab khoos phis tawj, mus rau qhov kub thiab txias, av noo, kev co, kev poob siab, thiab lwm yam ib puag ncig.
LIBMIL-STD-810H Test Chambersxa mus kuaj-kev simulations ntawm cov xwm txheej no. Los ntawm kev hloov cov qauv MIL-STD-810H txoj kev sim, suav nrog Txoj Kev 506.7 (Rain) thiab 510.7/510.8 (Blowing Plua plav thiab Xuab zeb), cov chav no muab cov kev sim rov ua dua, tswj xyuas kom zoo, kev sib khi ruaj khov, thiab kev ua haujlwm zoo. Nrog rau programmable airflow, particle concentration, thiab kev xeem mus ncig, cov tshuab no muab cov engineers thiab QA pab pawg muaj peev xwm los lees paub cov khoom siv rau kev xa tawm tiag tiag.
Los ntawm cov khoom siv rau kev sim nruj, cov tuam ntxhab tuaj yeem xyuas kom lawv cov khoom ua tau raws li cov qauv tsim nyog ntawm kev ua tau zoo thiab kev ntseeg siab. Ntxiv mus, MIL-STD-810H kev sim ua rau cov tuam txhab lag luam txheeb xyuas qhov muaj peev xwm tsis muaj zog lossis tsim qhov tsis zoo hauv lawv cov khoom thiab daws lawv ua ntej lawv mus txog kev ua lag luam.
1. Cov kev ntsuas tshwj xeeb thiab cov txheej txheem
Cov kev ntsuas tshwj xeeb thiab cov txheej txheem ntawm MIL-STD-810H sib txawv nyob ntawm cov khoom siv raug sim, tab sis muaj cov txheej txheem yooj yim uas muaj rau txhua yam khoom siv. Cov hauv qab no yog qee qhov yuav tsum tau ua thiab cov txheej txheem tseem ceeb:
