Seismic kubereka kwezvivakwa zvepamusoro-soro

Tsanangudzo Pfupi

Rubber isolation bearing rinonyanya kuumbwa nerabha rinobereka uye hari inotakura.Iyo ine moto inodzivirira, kusagadzikana kwemamiriro ekunze uye kusimba.Inogona kumira yakadzokororwa kugera pasina kudzikisa viscosity, uye inogona kugara ichichengetedza yakagadzikana damping simba.Iyo viscous shear simba inogadzirwa pakati pendiro yekupikisa yakaiswa mukati meiyo viscous material uye iyo viscous material inoshandiswa kutora nekubvisa simba rekuzunguza, ukuwo chimiro chebhiriji chichitsigirwa nendiro inotakura pabearing base plate.

Izvo zvikamu zvekuzviparadzanisa zverubha zvekuzviparadzanisa mabearings zvinogona kukamurwa kuita mapoka maviri: ekuzviparadzanisa nevamwe (isolators) uye dampers.Iyo yekutanga inogona kutsigira zvakafa uremu uye mutoro wezvivakwa, nepo yekupedzisira inogona kudzora deformation yakakura panguva yekudengenyeka kwenyika, uye inotora chikamu mukukurumidza kumira kuzununguka mushure mekudengenyeka kwenyika.

Iyo shear wave inogadzirwa panguva yekudengenyeka kwenyika zvakare chimwe chezvinhu zvakakosha zvinoita kuti zambuko rifambe nepakati.Muindasitiri yeinjiniya yemugwagwa uye yebhiriji yenyika yedu, kana kuoma kwakamira kwerabha yekuzviparadzanisa nevamwe kunochengetedzwa, iyo yakatwasuka inotakura simba curve ine mutsara, uye yakaenzana damping ratio ye hysteresis curve inenge 2%;

Kune mabheji erubha, kana kutenderera kwakadzika kunowedzera, kuoma kwakaenzana kwe hysteresis curve kuchaderera kune imwe nhanho, uye chikamu chesimba rinogadzirwa nekudengenyeka kwenyika richashandurwawo kuva simba rekupisa re rubber bearings;Pamabhengi erabha, iyo yakaenzana yekunyorovesa reshiyo inoita kunge isingachinji, uye kuomarara kwakaenzana kwemabhengi erubha kunopesana neyakachinjika kusimuka.

Tora mugwagwa uye bhiriji chirongwa chataurwa pamusoro apa semuenzaniso.Muchigadziro chekuvaka, kushushikana kunokonzerwa nekureba kwebhiriji rose kunofungidzirwa zvizere.Paunenge uchishandisa, tambo dzesimbi dzinoenderana dzakaiswa kuti dzipe iyo yakakodzera lateral yekutsigira simba renzira yese uye bhiriji chirongwa, uye panguva imwe chete, kuramba kunogona kuwedzera.Pahwaro uhwu, iyo yakagadzirirwa kusimuka kwemabhengi ekuzviparadzanisa nerubha ndeye 271mm.
