(2) Qhov hluav taws xob maj mam nce mus rau qhov ntsuas hluav taws xob ntawm qhov ruaj khov thiab tsis sib xws nyob rau hauv 5s, thiab qhov hluav taws xob tau khaws cia kom txog thaum lub xau tam sim no ruaj khov rau tsawg kawg 1 min.
5) Ntsev
Hauv kev daws brine, cov ntsev ntau suav nrog 5% ntawm qhov loj ntawm cov dej distilled. Tus nqi pH yog nyob nruab nrab ntawm 6.5 thiab 7.2, thiab qhov ceev yog 1.026 txog 1.040 ntawm 35 degree. Khaws qhov kub hauv tsev nyob rau thaj tsam ntawm 33 ° ~ 36 ° C. Soak rau 3 hnub.
6) Cua load
Lub rooj sib txoos yog mounted rau ntawm tus ncej thiab raug rau 2400Pa sib npaug rau 200 km / h cua, alternating rov qab mus rau 10, 000 cycles. Nws yog los simulate cua hnyav heev thiab xyuas kom xoob kev sib cuag thiab ua tau roj teeb puas.
7) Twist
Kev sib dhos yog tsau ntawm peb lub ces kaum thiab lub kaum plaub yog tsa los ntawm 1 ", tom qab ntawd cov cua txias thiab lub zog yog simulated los xyuas cov roj teeb puas thiab tsis muaj hluav taws xob tiv tauj.
8) Kev kho cua sov ntev
(1) Cov khoom raug khaws cia ntawm 90% txheeb ze av noo thiab 90 degree C rau 5 hnub kom paub meej tias kev tiv thaiv kev nkag mus ntawm noo noo.
(2) Vibration test: acceleration 2g, XYZ peb qhia, txhua 2h.
2. Kev kuaj ib puag ncig
1) Kub hloov pauv
(1) Rov ua dua qhov hloov pauv ntawm qhov kub thiab txias mus rau qhov kub qis yog hu ua kub hloov pauv.
(2) Qhov kub thiab txias: -40± 3 ~ +35± 2 degree .
(3) Tempered iav npog phaj sib dhos alternates 200 zaug, thiab zoo iav npog phaj sib dhos alternates 50 zaug.
2) Kev kub ceev cia
Lub hnub ci cell module rau hauv av yuav tsum khaws cia ntawm qhov kub thiab txias ntawm 85 ± 2 degree rau 16h.
3) Tsawg kub cia
Lub hnub ci cell module rau hauv av yuav tsum khaws cia ntawm qhov kub thiab txias ib puag ncig ntawm -40± 3 degree rau 16h.
4) Tsis tas li ntub dej kub cia
(1) Cov khoom siv hluav taws xob hnub ci rau hauv av yuav tsum tau muab tso rau hauv qhov chaw ntub thiab kub ntawm 90% mus rau 95% thiab qhov kub thiab txias yog +40± 2 degree rau 4 hnub.
(2) Thaum kawg ntawm qhov kev sim, ntxiv rau qhov kev ntsuas hluav taws xob ua haujlwm thiab kev tshuaj xyuas zoo li qub, lub rwb thaiv tsev kuj yuav tsum tau kuaj xyuas.
5) Kev vibration, poob siab: lub hom phiaj yog los ntsuas nws lub peev xwm tiv thaiv kev thauj mus los.
Kev vibration zaus: 10 ~ 55Hz
Amplitude: 0.355mm
Lub sijhawm vibration: ib txwm 20min. Tangential 20 min
Impact waveform: ib nrab sine, trapezoid, post-peak sawtooth, kav ntev 11ms
Peak acceleration ntawm kev cuam tshuam: 150m / s2
Lub sij hawm cuam tshuam: ib txwm thiab tangential 3 zaug txhua.
6) Kev ntsuam xyuas hauv av hnub ci irradiation
(1) Qhov kev sim tau ua nyob rau hauv lub simulated hauv av hnub ci irradiation kuaj chamber.
(2) Lub hnub ci simulated yuav tsum irradiate cov tivthaiv vertically, lub illuminance yog 1.12 ± 10% kW, thiab muaj spectral tis ntawm lub hnub ci hauv av.
7) Khoov kuaj
Nyob rau hauv chav tsev kub ntawm 15 ~ 35 degree, peb lub ces kaum ntawm lub hnub ci cell module yog tsau, thiab lwm lub ces kaum yog ntsia rau ntawm lub dabtsi yog khoov tester, thiaj li hais tias ib tug luv luv ntawm cov tivthaiv yog twisted los ntawm 1.2 degree, thiab cov tsos. thiab kev ua haujlwm hluav taws xob raug tshuaj xyuas tom qab kuaj.
