Kev thauj khoom ntau dhau thiab kev txwv ntau dhau ntawm cov tsheb loj ua rau muaj kev puas tsuaj loj rau txoj kev chaw thiab ua rau muaj kev pheej hmoo siab ntawm kev nyab xeeb kev nyab xeeb, qhov teeb meem tshwj xeeb hauv peb lub tebchaws uas 70% ntawm kev nyab xeeb kev nyab xeeb yog vim lub tsheb thauj khoom ntau dhau thiab kev txwv ntau dhau. Qhov no ua rau kev poob nyiaj ncaj qha ntawm ze li 3 billion RMB, nrog kev poob los ntawm lub tsheb thauj khoom ntau dhau thiab dhau kev txwv ntawm txoj kev loj tshaj 30 billion RMB ib xyoos ib zaug. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau saib xyuas thiab saib xyuas cov tsheb loj dhau ntawm txoj kev loj.
Txhawm rau tswj hwm lub tsheb thauj khoom ntau dhau yam tsis muaj kev cuam tshuam kev thauj mus los, Txoj Kev Nyuaj Siab Hauv Kev Tsiv (WIM) txoj kev loj dynamic hnyav lub tswv yim tau tshwm sim. Cov txheej txheem no siv piezoelectric quartz sensors kom ntsuas lub tsheb hnyav thaum lub tsheb hla ntawm txoj kev ntawm qhov nrawm (<120km / h) thiab ua rau lub koob yees duab saib xyuas kev yees duab.
Enviko quartz sensors tshwj xeeb yog tsim los rau cov nqi qis, ua haujlwm siab piezoelectric quartz sensors rau txoj kev loj dynamic hnyav thiab tiv thaiv choj. Tsim los nrog lub zog siab aerospace aluminium alloy thiab precision machining, cov sensors muaj siab compressive, tensile, dabtsi yog khoov, shear, thiab qaug zog load kuj. Los ntawm kev laus kev kho mob, sensor rhiab heev nyob ruaj khov rau xyoo lawm.
Internally ntim nrog tshwj xeeb elastic insulating muab tshuaj txhuam, Enviko quartz sensors ruaj khov nyob rau hauv lub siab, zoo thaiv cov dej noo, nrog ib tug raug rwb thaiv tsev impedance tus nqi ntawm 200GΩ.
Embedded nyob rau hauv txoj kev nto, thaum lub tsheb hla dhau, lub log nias rau ntawm lub sensor lub bearing nto, ua rau cov quartz muaju nyob rau hauv lub sensor los tsim nqi vim lub piezoelectric nyhuv. Tus nqi yog tam sim no amplified los ntawm ib tug sab nraud charge amplifier rau hauv ib tug voltage teeb liab, uas yog ncaj qha proportional rau lub siab thov mus rau lub sensor. Los ntawm kev suav cov teeb liab siab, qhov hnyav ntawm txhua lub log thiab yog li qhov hnyav tag nrho ntawm lub tsheb tuaj yeem tau txais.
Lub siab-them nqi piv tus yam ntxwv ntawm piezoelectric quartz sensors tseem tsis hloov tsis hais qhov kub, sijhawm, qhov loj me, thiab qhov ceev ceev. Yog li ntawd, txawm tias thaum lub tsheb hla dhau qhov ntsuas qhov chaw ntawm kev kub ceev, quartz sensors tuaj yeem tswj tau qhov ntsuas qhov tseeb.
Tom qab WIM sensors tau kos rau hauv txoj kev nto, lawv raug tshav ntuj, nag, thiab lub log siab, ua qhov kev ntsuam xyuas kev ntseeg tau tseem ceeb heev.
Temperature and Humidity Cycling Test:
Sensors nrog bearing nto yog muab tso rau hauv ib puag ncig kuaj chamber rau -40 ℃ to 85 ℃ kub thiab humidity cycling xeem rau 500 teev. Thaum lub sij hawm xeem, lub rwb thaiv tsev impedance ntawm lub sensors yuav tsum tsis txhob qis dua 100GΩ. Tom qab ntsuas ntsuas kub thiab av noo, cov sensors tau txais kev tiv thaiv kev tiv thaiv thiab kev qaug zog load.
Fatigue Load Test:
Kev ntsuas kev qaug zog siv lub zog ntawm 6000N siv lub taub hau steel siab nrog qhov dav ntawm 50mm x 50mm ntawm peb txoj haujlwm ntawm qhov ntsuas qhov kawg thiab nruab nrab, nrog kev thauj khoom thiab tshem tawm ib zaug ib zaug, tag nrho 1,000,000 qaug zog loads. Qhov kev hloov pauv hloov pauv ntawm qhov ntsuas qhov ntsuas yuav tsum yog <0.5%, thiab yuav tsum tsis txhob muaj kev puas tsuaj lossis tshem tawm ntawm cov kabmob nto.
Kev tiv thaiv rwb thaiv tsev:
Kev ntsuas kev tiv thaiv kev tiv thaiv muaj kev cuam tshuam tag nrho ntawm lub sensor hauv dej, caij tsheb kauj vab ntawm chav tsev kub thiab 80 ℃, nrog rau tag nrho cov sijhawm ntsuas ntawm 1000 teev. Thoob plaws hauv tag nrho cov kev xeem, lub rwb thaiv tsev tsis kam ntawm lub sensor yuav tsum tsis txhob qis dua 100GΩ.
Lub linearity ntawm piezoelectric quartz sensor signals yog ib qho tseem ceeb qhia txog kev tsim khoom thiab raug. Zoo heev piezoelectric quartz sensors xyuas kom FSO <0.5% thoob plaws tag nrho ntau yam. Rau WIM sensors, qhov yuam kev rhiab heev ntawm txhua txoj haujlwm raws li qhov ntev ntawm lub sensor yuav tsum tsis pub tshaj 2%. Yog li ntawd, nruj thiab meej rhiab heev soj ntsuam cov cuab yeej yog ib qho tseem ceeb rau sensor manufacturing.
Lub loading yam ntxwv nkhaus ntsuas lub zog-them nkhaus thiab linearity yuam kev (% FSO) thaum lub sij hawm loading thiab unloading nrog ib tug dav ntawm 100 hli loading taub hau siv rau lub sensor ntawm txhua txoj hauj lwm.
Lub teeb liab flatness tus yam ntxwv nkhaus ntsuas qhov rhiab heev tus nqi thaum lub sij hawm thauj khoom raws li qhov ntev ntawm lub sensor (tsis muaj qhov bearing nto) siv 50mm dav siab lub taub hau nrog ib tug quab yuam ntawm 8000N, nrog rhiab heev qhov tseem ceeb tau txais ntawm txhua lub loading test point siv los xam cov teeb liab flatness raws qhov ntev kev taw qhia ntawm lub sensor.
Txawm li cas los xij, qee cov tuam ntxhab txhob txwm siv lub 250mm dav loading siab lub taub hau rau cov teeb liab flatness kuaj, sib npaug rau 5 zaug nruab nrab ntawm tus yam ntxwv nkhaus, ua rau qhov tseeb ntawm 1%. Tsuas yog cov teeb liab tau txais los ntawm kev ntsuas kev thauj khoom siv lub taub hau dav dav 50mm tuaj yeem cuam tshuam qhov tseeb thiab qhov zoo ntawm lub sensor.
