1. Tanthauzo la Mphamvu Yodzaza Axial Panthawi Yotsitsimula M'malo
Mphamvu ya axial yomwe idadzaza kale panthawi yosinthira bracing imatanthawuza kutsitsa komwe kumapangidwa ndi kusinthika kwa membala kumapeto kwa chitsulo chothandizira panthawi yosinthira bracing, yomwe imadziwikanso kuti prestress kapena pretension.
2. Njira yowerengera
Mphamvu ya axial yodzaza kale panthawi yosinthira bracing imatha kuwerengedwa pogwiritsa ntchito njira iyi:
ΔN = δS·E·A
Kumene ΔN ndi mphamvu ya axial yodzaza kale panthawi yotsitsimutsa, yofotokozedwa mu Newtons (N).
δS ndi kuchuluka kwa kuuma, komwe kumawonetsedwa mu mm/kN.
E ndiye mtundu wa zinthu za elasticity, wofotokozedwa mu kN/mm².
A ndi gawo lamembala, lomwe limawonetsedwa mu mm².
M'mawerengedwe enieni, kuuma kokwanira kumatha kuwerengedwa kutengera zinthu monga kutalika kwa membala, miyeso yopingasa, ndi zinthu zotanuka modulus. The zinthu zotanuka modulus wa zitsulo thandizo angapezeke mwachindunji specifications mapangidwe, pamene membala mtanda-gawo miyeso ndi kutalika angapezeke kudzera muyeso weniweni.
3. Nkhani Zoyenera Kudziwa
1. Kuganizira Milandu Ina Yapadera
M'mapulojekiti enieni, okonza amafunika kuganizira zochitika zina zapadera. Mwachitsanzo, kuchepa kwa zinthu zotanuka modulus pa kutentha kwa ntchito, kupotoza kwa membala, ndi mpumulo wa katundu wakunja zitha kukhala zifukwa.
2. Chikoka cha Kuuma Coefficient
Kuwuma kokwanira ndikofunikira pakuwerengera mphamvu yojambulitsa panthawi yachitsulo. Choncho, okonza ayenera kuwerengera bwino ndi kulingalira kuti atsimikizire kulondola kwa chiwerengero cha preload force.
3. Kukhathamiritsa Kwa Mapangidwe Onse
Pakukonza, mphamvu yodzaza kale panthawi yopangira zitsulo imatha kuchepetsedwa pokonza mapangidwe onse ndikugwiritsa ntchito njira zambiri zamapangidwe asayansi. Mwachitsanzo, izi zitha kuphatikizira kukhathamiritsa magawo am'mamembala ndikukonzekera mwanzeru zothandizira mamembala.
Mwachidule, kuwerengera mphamvu yodzaza nthawi yachitsulo ndi ntchito yofunika kwambiri pakupanga uinjiniya. Pamafunika kuganizira zinthu zingapo, kuphatikiza zotanuka modulus, kutalika kwa membala, miyeso yopingasa, ndi kuuma kokwanira. Kuphatikiza apo, malingaliro apadera ayenera kupangidwa kuti awonetsetse kuti uinjiniya umapangidwira bwino.
