Kwimveliso yethu yamashishini, iibholithi zihlala ziqhekeka, kutheni ke iibholithi ziqhekeka? Namhlanje, ihlalutywa ikakhulu kwiinkalo ezine.
Ngapha koko, uninzi lokuqhawuka kweebholiti kungenxa yokukhululeka, kwaye zophukile ngenxa yokukhululeka. Ngenxa yokuba imeko ye-bolt yokukhulula kunye nokuphuka ifana neyokuphuka kokukhathala, ekugqibeleni, sinokuhlala sifumana isizathu esivela kumandla okukhathala. Enyanisweni, amandla okudinwa makhulu kangangokuba asinakucinga, kwaye iibholithi azifuni amandla okudinwa kwaphela ngexesha lokusetyenziswa.
Okokuqala, ukwaphuka kwebholithi akubangelwa kukuqina kwebholithi:
Thatha i-M20 × 80 ibanga le-8.8 ibholithi yokuqina okuphezulu njengomzekelo. Ubunzima bayo buyi-0.2kg kuphela, ngelixa ubunzima bayo obuncinci be-tensile bungama-20t, obuphezulu njenge-100,000 ubunzima bayo. Ngokubanzi, siyisebenzisa kuphela ukuqinisa iinxalenye ze-20kg kwaye sisebenzise kuphela iwaka lomthamo walo ophezulu. Naphantsi kwesenzo seminye imikhosi kwisixhobo, akunakwenzeka ukuba ugqobhoze amaxesha aliwaka obunzima bamacandelo, ngoko ke amandla okuqina e-fastener ene-threaded anele, kwaye akunakwenzeka ukuba ibholt yonakaliswe ngenxa amandla angonelanga.
Okwesibini, ukuphuka kwebholiti akubangelwa kukudinwa kwamandla ebholithi:
Isiqhoboshi sinokukhululwa izihlandlo ezilikhulu kuphela kumfuniselo wokukhulula wokungcangcazela, kodwa kufuneka singcangcazele amaxesha esisigidi ngokuphindaphindiweyo kumfuniselo wamandla wokudinwa. Ngamanye amazwi, i-fastener ene-threaded iyakhulula xa isebenzisa ishumi lamawaka lamandla ayo okudinwa, kwaye sisebenzisa kuphela ishumi lamawaka lamandla alo amakhulu, ngoko ke ukukhulula i-fastener ene-threaded akubangelwa kumandla okudinwa kwebholithi.
Okwesithathu, esona sizathu somonakalo weziqhoboshi ezinemisonto kukukhululeka:
Emva kokuba i-fastener ikhululiwe, kuveliswa amandla amakhulu e-kinetic mv2, esebenza ngokuthe ngqo kwisibophelelo kunye nezixhobo, ezibangela ukuba isibophelelo sonakaliswe. Emva kokuba i-fastener yonakaliswe, izixhobo azikwazi ukusebenza kwiimeko eziqhelekileyo, ezikhokelela ngakumbi kumonakalo wezixhobo.
Umsonto ojijwayo wesibophelelo esiphantsi kwamandla e-axial uyatshatyalaliswa kwaye ibholithi iyatsalwa.
Kwiziqhoboshi eziphantsi kwamandla emitha, ibholithi iyachetywa kwaye umngxuma webholithi ube ovali.
Okwesine, khetha indlela yokutshixa intambo enesiphumo esihle sokutshixa yeyona nto ibalulekileyo ukusombulula ingxaki:
Thatha ihamile yehydraulic njengomzekelo. Ubunzima behamile ye-GT80 ye-hydraulic yi-1.663 yeetoni, kwaye iibholithi zayo ezisecaleni ziyi-7 iiseti ze-M42 zeklasi ye-10.9. I-tensile force yebholiti nganye ziitoni ezili-110, kwaye amandla okuqina abalwa njengesiqingatha samandla okuqina, kwaye amandla okuqina aphakame kangangeetoni ezingamakhulu amathathu okanye amane. Nangona kunjalo, ibholithi iya kwaphuka, kwaye ngoku ilungele ukutshintshwa ibe yi-M48 bolt. Esona sizathu sikukuba ukutshixa ibholithi akukwazi ukuyisombulula.
Xa ibholithi igqabhuka, abantu banokugqiba ngokulula ukuba amandla ayo akonelanga, ngoko ke uninzi lwabo lwamkela indlela yokunyusa umgangatho wamandla wedayamitha yebholiti. Le ndlela inokunyusa amandla okuqina kwangaphambili kweebholiti, kwaye amandla ayo okukhuhlana nawo anyuswe. Ngokuqinisekileyo, umphumo ochasene nokukhulula unokuphuculwa. Nangona kunjalo, le ndlela ngokwenene yindlela engeyiyo ingcali, kunye notyalo-mali oluninzi kunye nenzuzo encinci kakhulu.
Ngamafutshane, ibholithi ithi: “Ukuba awuyikhulula, iya kwaphuka.”
