Ibanga lentsebenzo yeBolt, eyile ibakala lokusebenza kwebholiti yoqhagamshelo lwesakhiwo sentsimbi, yahlulwe ngamanqanaba angaphezu kwe-10, afana ne-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, njl. Amacandelo amabini, ngokulandelelanayo amele ixabiso le-tensile lamandla kunye nomlinganiselo wamandla okugoba wemathiriyeli yebholithi.
Intsingiselo yomgangatho wokusebenza kwebholithi ngumgangatho jikelele wamazwe ngamazwe, ibholithi yomgangatho ofanayo wokusebenza, kungakhathaliseki umahluko wezinto zayo kunye nemvelaphi, ukusebenza kwayo kuyafana, uyilo lunokukhetha kuphela ibakala lokusebenza.
Amandla enqanaba le-8.8 kunye ne-10.9 ubukhulu bubhekiselele kwinqanaba loxinzelelo lokucheba lwebholithi yi-8.8 GPa kunye ne-10.9 GPa 8.8 amandla okuqina angama-800 n / 640 n ibizibholithi zamandla emveliso/yaye ngokuqhelekileyo ibonakaliswa ngamandla “XY”, X * I-100 = i-bolt yamandla e-tensile, i-X * 100 * (Y / 10) = amandla emveliso yebholithi (njengoko kuchaziwe kwilogo: isivuno / amandla okuqina = Y / 10, oko kukuthi 0. Y ebonisa) njengobukhulu be-4.8, Amandla okuqina ebholithi: 400 mpa. Amandla esivuno: 400 * 8/10 = 320MPa.Enye: iibholiti zentsimbi etyiwayo zihlala zibhalwe A4-70, inkangeleko ye-A2-70, oku kuthetha ukuba cacisa ngenye indlela imilinganiselo: iyunithi yokulinganisa ubude. kwihlabathi namhlanje kukho iindidi ezimbini eziphambili, enye yenkqubo yemetric, iyunithi yokulinganisa yimitha (m), iisentimitha (cm), mm (mm), njl., eYurophu, eChina naseJapan kunye nokunye ukusetyenziswa kwe-Asia-mpuma ye-Asia. ngaphezulu, enye IsiNgesi, iyunithi yokulinganisa ubukhulu becala i-intshi (intshi), isetyenziswa ngokubanzi eUnited States, eBritani nakwamanye amazwe aseYurophu naseMelika.1. Umlinganiselo wenkqubo yemetriki: 1m =100 cm=1000 mm2, umlinganiselo wenkqubo yesiNgesi: (8) 1 intshi =8 ints 1 intshi =25.4 mm
Iibholiti ezisetyenziselwa ukudityaniswa kwezakhiwo zentsimbi zinamabakala angaphezu kwe-10, kubandakanywa i-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 kunye ne-12.9. Ileyibhile yomgangatho wokusebenza weBolt iquka iinxalenye ezimbini, ezimele ngokulandelelana ixabiso lamandla e-tensile kunye ukugoba amandla omlinganiselo wemathiriyeli yebholiti.Umzekelo: iibholithi ezinomlinganiselo wokusebenza 4.6, okuthetha ukuthi:
1. Amandla okuzinza okubizwa ngokuba yi-bolt material afikelela kuma-400MPa;
2. Umlinganiselo wamandla okugoba we-bolt material ngu-0.6;
3. Amandla emveliso yebholithi afikelela kuma-400×0.6=240MPa iklasi
Ibanga lokusebenza 10.9 bolt amandla aphezulu, izinto zayo emva unyango ubushushu, unako ukufikelela:
1. Amandla okuzinza okubizwa ngokuba yi-bolt material afikelela kwi-1000MPa;
2. Umlinganiselo wamandla okugoba we-bolt material yi-0.9;
3. Amandla emveliso yebholithi afikelela kwi-1000×0.9=900MPa iklasi
