Chii chinonzi tuned mass damper?
A tuned mass damper (TMD), inozivikanwawo seharmonic absorber, mudziyo wakaiswa muzvimiro kudzikisa amplitude yemakanika vibrations.Kushandisa kwavo kunogona kudzivirira kusagadzikana, kukuvara, kana kutadza kwemaitiro.Ivo vanowanzo shandiswa mukufambisira magetsi, mota, uye zvivakwa.Iyo tuned mass damper inoshanda zvakanyanya apo mafambiro echimiro anokonzerwa neimwe kana akawanda eresonant modhi yechimiro chekutanga.Muchidimbu, iyo TMD inobvisa simba rekuzunguza (kureva, rinowedzera kunyorova) kune iyo yekumisikidza modhi iyo "yakagadzirirwa" kwairi.Mhedzisiro yekupedzisira: chimiro chinonzwa chakaomarara kupfuura zvachiri chaizvo.

Iyo tuned mass damper inoshanda sei?
A TMD musanganiswa wezvitatu zvakakosha masisitimu: misa system, kuomarara system, uye simba dissipation (damping) system, saka kune matatu maitiro ekugadzirisa anodiwa mukugadzirwa kweTMD.Iko kuomarara uye kuwanda kweTMD kunosarudzwa kuti ipe TMD resonance frequency iri padyo neiyo resonance frequency.Iyo TMD yekunyorovesa nhanho inosarudzwa kuti ikwidzise kunyura kwesimba pamusoro peiyo inoshanda bandwidth yeTMD.Iyo TMD misa inosarudzwa kuti ipe iyo inodiwa nhanho yekuzunguza kudzikisira.Uye kana iyo vibration yasvika kune chimiro, iyo TMD ichagadzira simba rakapesana rine frequency yakafanana yekudengenyeka.Izvo zvichabatsira kuderedza uye kudzora vibration zvinobudirira.
Ndeipi iyo tuned mass damper inoshanda?
Iyo tuned mass damper inokodzera kureba uye zvivakwa zvinopenya uye zvimiro zviri nyore kukurudzirwa nekunze chinhu (semhepo, kufamba kwevanhu).Inogona kuderedza zvinobudirira kudengenyeka kunokurudzirwa nezvinhu zvekunze.Iwo maTMD anoshandiswa zvakanyanya munzvimbo dzinotevedzwa dzekushandisa.
1, Mabhiriji, pyller yemabhiriji, chimuney, tv tower uye zvimwe zvivakwa zvirefu uye zvinopenya zvinove nyore kumutswa nemhepo.
2, Ladder, odhitoriyamu, mutyairi tsoka-bhiriji uye zvimwe zvishandiso zvinomutswa nekufamba nekusvetuka kwevanhu.
3, Indasitiri chirimwa uye zvimwe zvivakwa zvesimbi zvivakwa uye zvivakwa zviri nyore kusimudzirwa neyakajairwa kuwanda kwemichina.
Iyo TMD iri pasi pekuyedzwa kwekufamba & kusvetuka muairport
Iyo TMD inoshandiswa mupassenger tsoka-bhiriji
