Ingabe amandla e-axial yebhawodi nokulayisha kuqala kuwumqondo?

Amandla e-axial ye-Bolt namandla okuqinisa ngaphambili awawona umqondo ofanayo, kodwa ahlobene ngezinga elithile.

I-bolt axial force isho ukushuba noma ukucindezela okukhiqizwa kubhawodi, okukhiqizwa ngenxa yetorque namandla okuqinisa ngaphambilini asebenza kubhawodi.Lapho ibhawodi iqiniswa, i-torque namandla okuqinisa ngaphambili asebenza kubhawodi ukuze kukhiqizwe i-axial tension noma amandla okucindezela, okungamandla e-axial yebhawodi.

Ukulayisha kuqala ukushuba kokuqala noma ukuminyanisa okusetshenziswa ngaphambi kokuba ibhawodi liqiniswe.Uma ibhawudi liqiniswa, ukulayisha kuqala kudala amandla e-axial tensile noma acindezelayo kubhawodi bese kucindezela izingxenye ezixhunyiwe ndawonye.Usayizi wokulayisha kuqala ngokuvamile unqunywa inani le-torque noma ukunwetshwa.

Ngakho-ke, amandla okuqinisa ngaphambili angesinye sezizathu ze-axial tensile noma amandla okucindezela ebhawodi, futhi kungenye yezinto ezibalulekile ezilawula i-axial tensile noma amandla okucindezela ebhawodi.

Buyini ubudlelwano phakathi kokulayisha kuqala kwebhawodi namandla ayo okukhiqiza?

Amandla angaphambi kokuqina adlala indima ebaluleke kakhulu ekubopheni nasekuxhumeni ama-bolts, futhi ubukhulu bawo kufanele bube obanele ukuze kubangele ama-bolts akhiqize ukungezwani kwe-axial, ngaleyo ndlela kuqinisekiswe ukuqina nokuphepha kwezingxenye zokuxhuma.

Amandla okukhiqiza ebhawodi asho amandla ebhawodi ukuze afinyelele ukuguqulwa kwepulasitiki noma ukwehluleka lapho ingaphansi kwe-axial tension.Uma ukulayisha kuqala kudlula amandla okukhiqiza ebhawodi, ibhawudi lingakhubaza unomphela noma lihluleke, kubangele ukuxega noma ukuhluleka.

Ngakho-ke, amandla okuqinisa ngaphambili webhawodi kufanele alawulwe ngaphakathi kwebanga elifanele, kungabi kukhulu kakhulu noma kuncane kakhulu, futhi kudinga ukunqunywa ngokuya ngezinto ezifana namandla okukhiqiza ebhawodi, izakhiwo zezinto ezibonakalayo, isimo sokucindezeleka sesixhumi, kanye nendawo yokusebenza.Ngokuvamile, amandla okuqinisa amabhawodi kufanele alawulwe ngaphakathi kwebanga elingama-70% ~ 80% lamandla okukhipha ibhawudi ukuze kuqinisekiswe ukuphepha nokuthembeka kokuxhuma.

Ayini amandla okukhiqiza ebhawodi?

Amandla okukhiqiza ebhawodi asho amandla amancane ebhawodi ashintshashintshayo uma ingaphansi kwe-axial tension, futhi ngokuvamile avezwa ngokwamandla eyunithi ngayinye (N/mm² noma MPa).Lapho ibhawodi lidonswa ngaphezu kwamandla ayo okukhiqiza, ibhawodi lizokhubazeka unomphela, okungukuthi, ngeke likwazi ukubuyela esimweni salo sasekuqaleni, futhi ukuxhumana kungase kuxege noma kuhluleke.

Amandla okukhiqiza amabhawodi anqunywa izici ezifana nezici ezibonakalayo nezimo zenqubo.Lapho uklama futhi ukhetha ama-bolts, kuyadingeka ukukhetha ama-bolts anamandla okukhiqiza anele ngokuya ngezidingo zezingxenye zokuxhuma nendawo yokusebenza nezinye izici.Ngesikhathi esifanayo, lapho uqinisa ama-bolts, kuyadingeka futhi ukucacisa usayizi wamandla okuqinisa ngaphambilini ngokusho kwamandla okukhiqiza ama-bolts, ukuze kuqinisekiswe ukuthi ama-bolts angakwazi ukuthwala umthwalo wokusebenza ngaphandle kokuguqulwa kwepulasitiki ngokweqile noma umonakalo.
