Ua - hauv particle damping thiab resonance suab nrov opualency opvessization ntawm elastic clips
Hom II clips muaj 75db suab nrov thiab 6% nkees tawg pleb vim muaj 300Hz resonance. Yuav ua li cas ntxiv cov particle damping, thiab dab tsi yog cov qauv?
Revonance Motioning lub zog ua rau muaj suab nrov thiab qaug zog. Kev Txhim Kho: ① × 20mm kab noj hniav hauv clip ntiv taw, 80% tau sau nrog 1-2mm tungsten hlau hais; ② Laser Vuam foob; ③ 0.5mm damping txheej. Cov Qauv: 40% resonance txo, tsawg dua los yog sib luag rau 70db suab nrov, tsawg dua los yog sib npaug / sib npaug nrog 2500km / h kab. Tau tshaj nrog cov fasteners uas twb muaj lawm.
Partic damping clips muaj 20% efficiency poob ntawm {}} 35 degree. Yuav ua li cas thiaj ua tau zoo dua cov ntsiab / txheej, thiab dab tsi yog qhov tsawg-temp yuav tsum tau?
Tsawg qhov kub nce particle qhov khoob. Optimization: ① cu - w pittles (0.8-1.5mm); ② polyurethane txheej (ntau dua lossis sib npaug ntawm 90% elasticity ntawm -35 degree); ③ roj silicone roj. Yuav tsum muaj: tsawg dua los yog sib npaug rau 101% kev ua kom muaj zog, tsawg dua lossis sib npaug nrog 51 tus neeg luag ntxhi, haum alpine kab.
Dab tsi yog kev sib tw / suab nrov kuaj / qauv rau cov pa damping clips, thiab yuav ua li cas reporks cov diav?
Kev kuaj xyuas qhov tseeb damping thiab kev ntseeg tau. Cov hau kev: ① resonance ntsuas; ②②hoic Chamber nrov nrov kuaj; ③ 1m kev sim nkees. Cov Qauv: Loj dua los yog sib npaug rau 35% resonance txo, tsawg dua los yog sib npaug rau 70db, tsis muaj xau. Reasce: ① Rov - Cav kab noj hniav; ② Tig Vuam foob; Kev ntsuas nruj me ntsis.
Dab tsi yog particle xaiv qhov sib txawv rau 200/250 / 300km / h kab, thiab muaj dab tsi tshwm sim nrog mismatch?
Qhov sib txawv: ① 200km / h: steel (7.8g / cm³), 100mm³; ② 250km / h: cu -} w (11g / cmle), 120mm³; ③ 300km / h: tungsten (19g / cmle), 150mm³. Lub hauv paus: Kev co zaus / lub zog. Mismatch: steel hais rau 300km / h: 74db suab nrov, 5% tawg.
Yuav ua li cas thiaj ua tau zoo clip - pa nyem thaiv kev thaiv, thiab ua li cas nrog kev sib txuam tsis zoo?
Kev txuam: ① hu rau thaj tsam txij li 15 txog 25mm²; Sange dos (ra tsawg dua los yog sib npaug rau 1.6μm); ON Cov roj nplua nyeem. Cov Qauv: Tsawg dua los yog sib npaug rau 0.5g nrawm, tsawg dua lossis sib npaug nrog 0.1mm hnav, loj dua lossis sib npaug ntawm 90% Damping khaws cia. Kev txuam tsis zoo: thaj chaw me me ua rau 15% damping poob, suab nrov dua.
