Lub tswv yim tsim ntawm cov roj hmab bushings yog kom tsis txhob thiab cais kev vibrations thiab cuam tshuam los ntawm elastic deformation, thaum precisely tswj nruj hauv ntau cov lus qhia kom ua tiav qhov sib npaug ntawm kev tuav lub tsheb thiab kev nplij siab.
Lub hauv paus ntsiab lus tsim yog nyob rau hauv kev siv lub superelasticity thiab siab damping zog ntawm cov ntaub ntawv roj hmab, ua ke nrog lub vulcanization molding ntawm ib tug hlau skeleton. Qhov no tso cai rau cov bushing tuaj yeem tiv taus cov khoom hnyav (xws li longitudinal rog, lateral force, thiab torsional moments) thaum ua kom muaj zog heev - zaus vibrations thiab txo suab nrov (NVH kev ua tau zoo). Los ntawm kev kho cov roj hmab hardness, geometry, skeleton qauv, thiab sab hauv txaus channel tsim, ywj siab tswj ntawm nruj nyob rau hauv lub axial, radial, thiab torsional cov lus qhia yuav ua tau.
Piv txwv li:
Pa roj hmab Bushings: Los ntawm kev hloov cov roj hmab thickness, zoo, thiab pob txha layout, lub dynamic - mus rau - zoo li qub stiffness ratio yog optimized kom tau raws li qhov yuav tsum tau ntawm kev ua tau zoo ntawm txawv installation txoj hauj lwm.
Hydraulic Bushings: Raws li cov qauv ib txwm muaj, lub kaw lus kaw thiab cov roj hydraulic tau qhia. Damping yog tsim los ntawm cov kua dej ntws, tswj cov lus teb mos hauv thawj theem thiab muab kev txhawb nqa muaj zog nyob rau theem kawg, ua tiav qhov "mos tab sis tsis xoob, ruaj tab sis tsis tawg" cov nyhuv.
