Roj hmab damping ntawm cov shock absorber thaum lub caij tseem ceeb, tau lug siv ntau hom kev machinery, tsheb, railway locomotives, dej thauj, aircraft, thiab lwm yam aircraft. Nws yuav hais tau tias txhua yam yuav kom haum poob siab thiab muab roj hmab shock absorbers no yuav tsum tau txhaj.
Roj hmab shock absorber yog li plhuav siv yog vim hais tias nws yog ib tug siv tau siv cov roj hmab ntawm cov yam ntxwv li nram no:
1) roj hmab kub elasticity thiab viscoelasticity;
(2) piv nrog hlau thiab steel khoom, elastic deformation roj hmab no loj heev, yog elastic modulus me me;
(3) poob siab mob heev yog dua tus mob heev dynamic roj hmab, ib yam li tus mob heev zoo li qub dynamic nruj, pab txo cov feem thiab dynamic deformation;
4) kev nyuaj siab-hom kev nkhaus rau qhov zoo li tus oval qeeb kab, thaj chaw uas nws yuav muab txhua kev co mus los rau hauv tshav kub kev co (damping), yuav raug tom los ntawm tus formulation ntawm;
5) yog roj hmab incompressible khoom (Poisson tus piv ntawm 0.5);
6) roj hmab puab muaj rau koj xaiv, tus hardness yuav tsum tom ntawm tus formulation, yuav raws li qhov yuav tsum ntau mob heev thiab ua tau.
