Nres Pad Factory Optimizes NVH Technology los daws cov teeb meem tom qab nres nres nres
Nres squeal thiab txawv txav suab nrov yeej ib txwm yog ib qho kev tsis txaus siab nyob rau hauv lub ntiaj teb no pib tom qab muag khoom. Raws li qhov kawg - cov neeg siv nrhiav kev tsav tsheb ntau dua, cov chaw tsim khoom lag luam nres tsheb tau txhim kho NVH (Ntsuab, Kev vibration, Harshness) tswj cov thev naus laus zis thiab kev sib txhuam cov qauv txhawm rau tshem tawm cov teeb meem cuam tshuam ntawm lub suab nrov thaum tswj hwm Euro 7 thiab ECE R90 kev nyab xeeb kev ua haujlwm.
Kev lag luam kev tshawb fawb qhia tau hais tias feem ntau lub suab nrov nres yog los ntawm siab - zaus resonance thiab tsis ruaj khov ntawm cov nres nres thiab rotors. Qhov xwm txheej "stick-slip" vibration tshwm sim tshwm sim thaum cov ntaub ntawv sib txhuam hloov tuav thiab tso lub nres nres, ua rau lub suab nrov nrov ntawm 1 kHz thiab 16 kHz, uas yog rhiab heev rau tib neeg pob ntseg. Ntau qhov qis- qib qis tom qab lub tshuab nres nres cia siab rau cov qauv ib nrab- xim hlau uas muaj cov ntsiab lus ntawm cov hlau fiber ntau, ua rau muaj kev sib txhuam tsis zoo, tsis zoo thiab lub suab nrov thaum lub sijhawm qis - nrawm nrawm thiab txias pib.
Sib nrug los ntawm cov khoom tsis xws luag, tsis tiav qhov chaw haum, kev laus damping accessories, tsis sib xws thermal expansion thiab lwm yam paug xws li hlau plua plav thiab xeb kuj ua rau lub suab nrov tsis tu ncua. Cov txheej txheem nias thiab kho tsis raug hauv cov chaw ua haujlwm zoo ib yam yooj yim ua rau micro- deformation ntawm daim hlau rov qab thiab kev sib txhuam tsis zoo ntawm qhov chaw tiaj tus, ua rau muaj kev vibration thiab suab nrov ntxiv.
Hauv kev teb rau cov kev sib tw nrov nrov tom qab kev lag luam, ua lag luam nres nres nres tau tsim cov kev daws teeb meem zoo NVH. Ua ntej, cov chaw tsim khoom siv cov tooj liab hloov kho dua tshiab -dawb ceramic thiab qis-cov qauv hlau uas muaj qhov sib npaug ntawm qhov tawv thiab qhov yooj yim, txo qis kev sib txhuam thiab siab - zaus vibration. Thib ob, precision CNC nto sib tsoo thiab arc calibration xyuas kom tag nrho kev sib cuag ntawm cov ntaub qhwv thiab discs, tshem tawm khiav - nyob rau hauv lub suab nrov tshwm sim los ntawm tsis zoo haum.
Tsis tas li ntawd, cov chaw tsim khoom tsim tau nruab txhua lub nres nres nrog ntau- txheej damping shims, kev tiv thaiv- suab nrov roj thiab cov khoom siv kho vajtse sib tw. Cov cuab yeej pabcuam no nqus cov micro-vibration thiab zam hlau-rau- hlau resonance. Kev ntsuas suab nrov thiab kev co simulation simulation yog ua nyob rau hauv lub chaw soj nstuam ywj pheej los lav qhov kev ua haujlwm zoo nyob ntsiag to nyob rau hauv txias, kub, qis-ceev thiab hnyav- load tej yam kev mob.
Kev lag luam tawm tswv yim qhia tias Euro 7- ua raws li lub suab nrov- qhov zoo tshaj plaws nres nres tau dhau los ua qhov kev xaiv tseem ceeb rau cov neeg muag khoom nyob sab Europe, tshwj xeeb tshaj yog rau BMW, Jeep thiab lwm lub tsheb thauj neeg nyob sab Europe, nrog rau hnyav - lub luag haujlwm tsheb thauj mus los. Cov khoom lag luam nrog kev ua tau zoo NVH txo qis tom qab- muag khoom rov qab thiab txhim kho cov neeg siv khoom txaus siab.
Raws li kev ua haujlwm zoo - tsom lub tshuab nres nres, Shandong Huiruifeng Machinery integrates formula optimization, precision manufacturing and full NVH testing. Tag nrho cov khoom muaj suab nrov, tsis tshua muaj plua plav, ruaj khov braking thiab muaj zog thermal ploj tsis kam, ua tau raws li ECE R90 cov qauv kev nyab xeeb thiab Euro 7 ib puag ncig cov cai. Lub tuam txhab txuas ntxiv muab qhov ntsiag to, siab - zoo thiab tus nqi- kev daws teeb meem braking zoo rau cov neeg siv khoom thoob ntiaj teb.
Kev lag luam sab hauv kwv yees tias NVH kev ua kom zoo dua yuav dhau los ua qhov kev sib tw tseem ceeb rau kev txhim kho lub tshuab nres nres hauv ob xyoos tom ntej. Cov neeg tsim khoom lag luam nrog cov cuab yeej tswj lub suab nrov yuav txuas ntxiv tuav lub siab -kawg European thiab thoob ntiaj teb tom qab kev lag luam.
