1. Tsanangudzo yePreloaded Axial Force Panguva Yekugadzirisa Kutsiva
Iyo preloaded axial simba panguva yekutsiviwa kwebracing inoreva iyo preload inogadzirwa nenhengo deformation munzvimbo yekupedzisira yerutsigiro rwesimbi panguva yekutsiviwa kwebracing, inozivikanwawo se prestress kana pretension.
2. Maitiro ekuverenga
Iyo preloaded axial simba panguva yekutsiva bracing inogona kuverengerwa uchishandisa inotevera formula:
ΔN = δS·E·A
Iko ΔN ndiyo yakarongedzerwa axial simba panguva yekusimudzira kushandiswa, inoratidzirwa muNewtons (N).
δS ndiyo coefficient yekuomarara, inoratidzwa mumm/kN.
E ndiyo zvinhu modulus ye elasticity, inoratidzwa mu kN/mm².
A ndiyo mhiri-chikamu nzvimbo yenhengo, inoratidzwa mumm².
Muchiverengero chaihwo, iyo stiffness coefficient inogona kuverengerwa zvichienderana nezvinhu zvakaita senge nhengo kureba, cross-sectional dimensions, uye zvinhu elastic modulus. Iyo zvinhu elastic modulus yerutsigiro rwesimbi inogona kuwanikwa yakananga mumagadzirirwo edhizaini, nepo nhengo inoyambuka-chikamu chiyero uye kureba inogona kuwanikwa kuburikidza nechiyero chaicho.
3. Nyaya Dzinofanira Kucherechedzwa
1. Kufunga Dzimwe Nyaya Dzinokosha
Mumapurojekiti chaiwo, vagadziri vanofanirwa kufunga nezvemamwe akakosha kesi. Semuyenzaniso, kudzikira kwechinhu elastic modulus pakushanda tembiricha, kutsauka kwenhengo, uye kudzoreredzwa kwemitoro yekunze zvese zvinogona kuve zvinhu.
2. Kufurira kweKuoma Kwesimba
Iyo yekuomarara coefficient yakakosha pakuverenga preload simba panguva yesimbi bracing. Naizvozvo, vagadziri vanofanirwa kuita maverengero akakwana uye kufunga kuti ive nechokwadi cheiyo preload simba rekuverenga.
3. Pakazara Dhizaini Optimization
Munguva yekugadzira maitiro, preload simba panguva yesimbi bracing inogona kuderedzwa nekugadzirisa iyo yakazara dhizaini uye nekushandisa dzimwe nzira dzesainzi dzekugadzira. Semuenzaniso, izvi zvinogona kusanganisira kukwidziridza nhengo dzakachinjika-zvikamu uye kuronga zvine hungwaru zvinotsigira nhengo.
Muchidimbu, kuverenga preload simba panguva yekusimbisa simbi ibasa rakakosha mukugadzira engineering. Zvinoda kutariswa kwezvinhu zvakawanda, kusanganisira iyo elastic modulus, kureba kwenhengo, mativi emuchinjika-chikamu, uye kuomarara coefficient. Zvakare, kutarisisa kwakakosha kunofanirwa kuitwa kuve nechokwadi chekugadzira engineering dhizaini.
