Iintambo zokunyuka zingohlulwa zibe ziintambo eziguquguqukayo kunye neentambo ezimileyo.Intambo eguquguqukayo ine-ductility elungileyo ukwenzela ukuba xa kukho ithuba lokuwa, intambo inokolulwa ukuya kumlinganiselo othile ukucothisa umonakalo owenziwe kukuwa okukhawulezayo kumkhweli.
Kukho iindlela ezintathu zokusebenzisa intambo eguqukayo: intambo enye, intambo esiqingatha, kunye nentambo ephindwe kabini.Iintambo ezihambelana nokusetyenziswa okuhlukeneyo zahlukile.Intambo enye yeyona isetyenziswa kakhulu kuba ukusetyenziswa kulula kwaye kulula ukuyisebenzisa;Isiqingatha sentambo, ekwaziwa ngokuba yintambo ephindwe kabini, isebenzisa iintambo ezimbini ukuba zidityaniswe kwindawo yokuqala yokhuseleko ngexesha elinye xa unyuka, kwaye ke iintambo zombini zibotshelelwe kwiindawo ezahlukeneyo zokhuselo ukuze icala lentambo lilungelelaniswe ngobukrelekrele ukukhuhlana entanjeni kunokuncitshiswa, kodwa kwandiswe ukhuseleko njengoko kukho iintambo ezimbini zokukhusela umkhweli.Nangona kunjalo, ayisetyenziswa ngokuqhelekileyo ekunyukeni intaba ngokwenene, kuba indlela yokusebenza yolu hlobo lwentambo inzima, kwaye abaninzi abakhweli basebenzisa indlela yesilingi kunye nokuxhoma ngokukhawuleza, enokuthi kwakhona ilungelelanise kakuhle indlela yentambo enye;
Intambo ephindwe kabini kukudibanisa iintambo ezimbini ezibhityileyo zibe nye, ukuze kuthintelwe ingozi yokusikwa nokuwa kwentambo.Ngokuqhelekileyo, iintambo ezimbini zohlobo olufanayo, imodeli, kunye nebhetshi zisetyenziselwa ukunyuka kweentambo;Iintambo ezinobubanzi obukhulu zinomthamo ongcono wokuthwala, ukuxhathisa i-abrasion, kunye nokuqina, kodwa nazo zinzima.Ukunyuka kwentambo enye, iintambo ezinobubanzi obuyi-10.5-11mm zifanelekile kwimisebenzi efuna ukuxhatshazwa okuphezulu, njengokunyuka kweendonga ezinkulu zamatye, ukwenza iifom ze-glacier, kunye nokuhlangula, ngokubanzi kwi-70-80 g / m.I-9.5-10.5mm ubukhulu obuphakathi kunye neyona nto isebenzayo, ngokubanzi i-60-70 g/m.Intambo ye-9-9.5mm ifanelekile ukunyuka okulula okanye ukunyuka kwesantya, ngokubanzi kwi-50-60 g / m.Ububanzi bentambo esetyenziselwa ukunyuka kwesiqingatha sentambo yi-8-9mm, ngokubanzi kuphela i-40-50 g/m.Ubukhulu bentambo esetyenziselwa ukukhwela intambo malunga ne-8mm, ngokubanzi kuphela i-30-45g/m.
Impembelelo
Amandla empembelelo sisalathisi sokugoba kwentambo, eluncedo kakhulu kubakhweli.Ixabiso eliphantsi, ngcono ukusebenza kwentambo yentambo, enokukhusela ngcono abakhweli.Ngokuqhelekileyo, amandla empembelelo yentambo angaphantsi kwe-10KN.
Indlela yokulinganisa ethile yamandla empembelelo yile: intambo esetyenziswe okokuqala iyawa xa inobunzima obungama-80kg (iikhilogram) kunye nemeko yokuwa (Fall Factor) yi-2, kunye nowona xinzelelo luphezulu lweebhere zentambo.Phakathi kwabo, i-coefficient yokuwa = umgama othe nkqo wokuwa / ubude bentambo esebenzayo.
Ukunyangwa kwamanzi
Emva kokuba intambo ifakwe, ubunzima buya kwanda, inani lokuwa liya kuncipha, kwaye intambo emanzi iya kukhenkcela kumaqondo aphantsi kwaye ibe yi-popsicle.Ke ngoko, ekunyukeni komgangatho ophakamileyo, kubaluleke kakhulu ukusebenzisa iintambo ezingangeni manzi ukukhwela umkhenkce.
Elona nani liphezulu lokuwa
Inani eliphezulu lokuwa luphawu lwamandla entambo.Kwintambo enye, inani eliphezulu lokuwa libhekisela kwi-coefficient yokuwa kwe-1.78, kwaye ubunzima bento ewayo yi-80 kg;Kwintambo yesiqingatha, ubunzima bento ewayo yi-55 kg, kwaye ezinye iimeko zihlala zingatshintshi.Ngokuqhelekileyo, inani eliphezulu lokuwa kwentambo ngamaxesha angama-6-30.
Ukwandiswa
I-ductility yentambo yohlulwe ibe yi-dynamic ductility kunye ne-static ductility.I-dynamic ductility imele ipesenti yolwandiso lwentambo xa intambo inobunzima be-80 kg kwaye i-coefficient yokuwa yi-2. Ukwandiswa okuzinzileyo kubonisa ipesenti yobude bentambo xa inobunzima obungama-80 kg xa iphumle.
