Kev vibration thiab suab nrov txo Cheebtsam rau kev tsheb ciav hlau hauv nroog
Dab tsi yog qhov tseem ceeb ntawm kev co thiab suab nrov hauv kev tsheb ciav hlau?
Log -rail dov tej yam, rail corrugation, taug qab qauv kev co, kev co kis tau tus mob ntawm fasteners thiab bearing daim hlau, thiab resonance nyob rau hauv lub tunnel / choj qauv. Kev co propagates hauv av, ua rau lub tsev swaying, suab nrov sab hauv tsev, thiab cuam tshuam nrog precision instruments.
Dab tsi yog cov qib kev vibration-damping track structures?
General vibration damping: zoo tib yam elastic fasteners; Nruab nrab vibration damping: elastic bearing daim hlau, roj hmab floating daim hlau; High-qib vibration damping: roj hmab floating phaj, caij nplooj ntoos hlav floating phaj; Tshwj xeeb kev co damping: steel caij nplooj ntoos hlav floating daim hlau (siab tshaj plaws kev co damping efficiency). Cov qib sib txawv raug xaiv rau ntau qhov chaw kom ua tiav "ntawm-xav tau kev co damping."
Dab tsi yog qhov tseem ceeb ntawm kev ua haujlwm ntawm kev vibration damping Cheebtsam?
Static stiffness, dynamic rigidity, dynamic -rau -static stiffness ratio; damping coefficient (dissipates vibration zog); qaug zog lub neej, creep, laus kev ua tau zoo; Vertical, lateral, thiab longitudinal stiffness matching.
Vim li cas thiaj li qis - cov kab nrib pleb tuaj yeem txo kev co?
Qhov qis qis, qhov zoo dua ntawm kev sib tw elasticity, qhov cuam tshuam me me, thiab qis dua qhov kev vibration kis. Txawm li cas los xij, qhov tawv nqaij tsis tuaj yeem qis dhau, txwv tsis pub nws yuav ua rau: qhov ntsuas tsis ruaj khov, lub tsheb ciav hlau swaying, rail hloov chaw, thiab kev puas tsuaj ntawm cov khoom tiv thaiv kev ntxhov siab. Yuav tsum muaj qhov sib npaug ntawm kev vibration txo cov nyhuv thiab kev ua haujlwm ruaj khov.
Kev saib xyuas ceev faj rau kev vibration-damped seem?
Nws yog nruj me ntsis txwv tsis pub arbitrarily hloov hom ntaub qhwv los yog fasteners; nws yog txwv tsis pub arbitrarily thicken los yog nyias cov ntaub qhwv txheej; tsis tu ncua xyuas kev laus, deformation, thiab kev puas tsuaj ntawm cov khoom elastic; tam sim ntawd tshawb xyuas qhov xwm txheej ntawm cov qauv thiab cov khoom nyob rau hauv cov ntaub ntawv ntawm kev co txawv txav los yog suab nrov.
