Umvavanyi wamandla obunzima phantsi kwemeko yokulayishwa kwesantya rhoqo, umzekelo wobungakanani obuchaziweyo unwenwe kwi-fracture, amandla okuqina alinganiswa, kunye nobude obuninzi kwi-fracture irekhodwa.
ⅠChaza
Ezi nkcazelo zilandelayo zamkelwe kulo Mgangatho wamazwe ngamazwe.
1,Amandla okuqina
Uxinzelelo olukhulu olunokuthi iphepha okanye ikhadibhodi likwazi ukumelana nayo.
2. Ukuqhawula ubude
Ububanzi bephepha ngokwalo buya kuhambelana nomgangatho wephepha buya kuphulwa xa ubude bufunekayo. Ibalwe ngokobungakanani ukusuka kumandla okuqina kunye nokufuma okungaguqukiyo kwesampulu.
3.Zolula ngexesha lokuphumla
Ukwandiswa kwephepha okanye ibhodi phantsi koxinzelelo lokuqhekeka, kubonakaliswa njengepesenti yobude bomzekelo wokuqala.
I-4, isalathisi se-tensile
Amandla okuqina ahlulwe ngobuninzi obuvezwa kwiimitha zeNewtons ngegram.
Ⅱ Isixhobo
Umvavanyi wamandla e-tensile kufuneka akwazi ukusetyenziselwa ukuvavanya amandla okuqina kunye nobude bomzekelo ngesantya esixeliweyo sokulayisha. Umvavanyi wamandla obunzima uya kubandakanya:
1. Isixhobo sokulinganisa kunye nokurekhoda
Ukuchaneka kokuchasana kwe-tensile kwi-fracture kufuneka kube yi-1%, kwaye ukuchaneka kokufunda kwe-elongation kufuneka kube yi-0.5mm. Uluhlu lomlinganiselo olusebenzayo lomvavanyi wamandla okuqina kufuneka lube phakathi kwe-20% kunye ne-90% yoluhlu lulonke. Qaphela: kwiphepha elinobude obungaphantsi kwe-2%, ukuba akuchanekanga ukusebenzisa i-pendulum tester ukumisela ubude, kufuneka kusetyenziswe i-speed tester kunye ne-electronic amplifier kunye nerekhoda.
2. Ukulungelelaniswa kwesantya sokulayisha
Qaphela: Ukuze uhlangabezane nemfuneko yokuba utshintsho lwesantya sokulayisha akufanele lube lukhulu ngaphezu kwe-5%, isixhobo sohlobo lwe-pendulum akufanele siqhutywe kwi-pendulum Angle enkulu kune-50 °.
3. Iiklip zesampulu ezimbini
Iisampulu kufuneka zibotshwe kunye kubo bonke ububanzi bayo kwaye akufanele zityibilike okanye zonakalise. Umgca osembindini we-clamp kufuneka ube yi-coaxial kunye nomgca ophakathi wesampuli, kwaye isalathiso samandla okubamba kufuneka sibe yi-1 ° ngokuthe nkqo ukuya kwisikhokelo sobude besampulu. Umphezulu okanye umgca weekliphu ezimbini kufuneka ube yi-1 ° parallel.
4, izithuba ezimbini zekliphu
Umgama phakathi kweziqeshana ezimbini ulungelelaniswa kwaye kufuneka ulungelelaniswe kwixabiso elifunekayo lokuvavanya ubude, kodwa impazamo ayifanele idlule i-1.0 mm.
Ⅲ Ukuthathwa kwesampulu kunye nolungiselelo
1, Isampuli kufuneka ithathwe ngokwe-GB / T 450.
I-2, i-15 mm kude nomda wesampulu, unqumle inani elaneleyo leesampuli, ukuqinisekisa ukuba kukho i-10 yedatha esebenzayo kwi-vertical and horizontal direction. Umzekelo kufuneka ungabi naziphene zephepha ezichaphazela amandla.
Amacala amabini esampuli aqondile, ukuhambelana kufuneka kube ngaphakathi kwe-0.1mm, kwaye ukusika kufuneka kucoceke ngaphandle komonakalo. Qaphela: xa usika iphepha elithambileyo elithambileyo, isampuli inokuthatyathwa ngephepha elilukhuni.
3, Ubungakanani besampuli
(1) Ububanzi besampulu kufuneka bube (15 + 0) mm, ukuba obunye ububanzi kufuneka buboniswe kwingxelo yovavanyo;
(2) Isampuli kufuneka ibe nobude obaneleyo ukuqinisekisa ukuba isampuli ayiyi kuchukumisa isampuli phakathi kweekliphu. Ngokuqhelekileyo ubude obufutshane besampuli yi-250 mm; Amaphepha abhalwe ngesandla kwilebhu aya kusikwa ngokwemigangatho yawo. Umgama wokubamba ngexesha lovavanyo kufuneka ube yi-180 mm. Ukuba ezinye ubude bomgama wokubamba zisetyenziswa, kufuneka ziboniswe kwingxelo yovavanyo.
ⅣAmanyathelo ovavanyo
1. Ukulungelelaniswa kwesixhobo kunye nohlengahlengiso
Faka isixhobo ngokomyalelo kwaye ulungelelanise indlela yokulinganisa amandla ngokweSihlomelo A. Ukuba kukho imfuneko, indlela yokulinganisa ubude nayo kufuneka ilinganiswe. Lungisa isantya sokulayisha ngokwe-5.2.
Lungisa umthwalo weeclamps ukwenzela ukuba umtya wovavanyo ungatyibiliki okanye wonakaliswe ngexesha lovavanyo.
Ubunzima obufanelekileyo bubotshelelwe kwikliphu kwaye ubunzima buqhuba isixhobo esibonisa ukulayisha ukurekhoda ukufundwa kwayo. Xa uhlola indlela ebonisa ngayo, indlela ebonisa ngayo ayifanele ibe ne-backbump eninzi, i-lag okanye i-friction. Ukuba impazamo inkulu kune-1%, ijika lokulungisa kufuneka lenziwe.
2, Ukulinganisa
Iisampuli zavavanywa phantsi kweemeko eziqhelekileyo zomoya wobushushu kunye nonyango lokufuma. Jonga inqanaba le-zero kunye nangaphambili nasemva kwendlela yokulinganisa kunye nesixhobo sokurekhoda. Lungisa umgama phakathi kweeclamps eziphezulu nezisezantsi, kwaye ubambe isampuli kwi-clamps ukuthintela ukudibana kwesandla kunye nommandla wovavanyo phakathi kweeclamps. Uxinzelelo lwangaphambili olumalunga ne-98 mN(10g) lusetyenziswa kwisampulu ukuze ibambeke ngokuthe nkqo phakathi kweekliphu ezimbini. Izinga lokulayishwa kokwaphuka (20 kumhlaba wesi-5) libalwe ngovavanyo oluqikelelweyo. Amandla aphezulu asetyenzisiweyo kufuneka abhalwe ukususela ekuqaleni kokulinganisa de i-specimen iyaphuka. Ubude bexesha lekhefu kufuneka burekhodwe xa kukho imfuneko. Ubuncinci iziqwenga ezili-10 zephepha kunye nebhodi kufuneka zilinganiswe kwicala ngalinye kwaye iziphumo zazo zonke iziqwenga ezili-10 kufuneka zisebenze. Ukuba i-clamp iphukile ngaphakathi kwe-10 mm, kufuneka ilahlwe.
ⅤIziphumo zibaliwe
Iziphumo zibonise ukuba iziphumo ezithe nkqo nezithe tyaba zephepha kunye nekhadibhodi zabalwa kwaye zamelwa ngokulandelelanayo, kwaye akukho mahluko kwicala lelabhoratri ekhutshelwe ngesandla amaphepha.
Ngokomgangatho "GB/T 453-2002 IDT ISO 1924-1:1992 iphepha kunye nebhodi tensile amandla ukuzimisela (indlela yokulayisha rhoqo ngesantya)" inkampani yethu iphuhlise iimveliso DRK101 series electronic umatshini wokuvavanya tensile. Inezi mpawu zilandelayo:
I-1, indlela yokuhambisa ithatha i-screw yebhola, ukuhanjiswa kuzinzile kwaye kuchanekile; Injini ye-servo engenisiweyo, ingxolo ephantsi, ulawulo oluchanekileyo.
2, Ukubonisa ukusebenza kwesikrini, isiTshayina kunye nemenyu yokutshintshiselana ngesiNgesi. Umboniso wexesha lokwenyani lexesha lamandla, ukuguqulwa kwamandla, ukufuduswa ngenkani, njl. njl Isixhobo sinokubonisa idatha enamandla, ukuhlalutya kunye namandla okulawula.
I-3, Ukusetyenziswa kwe-24-bit high precision AD converter (isisombululo ukuya kwi-1 / 10,000,000) kunye ne-sensor echanekileyo yokulinganisa i-sensor, ukuqinisekisa ukukhawuleza kunye nokuchaneka kwesixhobo sokufumana idatha.
4, Ukusetyenziswa komshicileli wemodyuli ye-thermal, ukufakwa lula, impazamo ephantsi.
I-5, Iziphumo zokulinganisa ngokuthe ngqo: emva kokugqitywa kweqela leemvavanyo, kulungele ukubonisa ngokuthe ngqo iziphumo zokulinganisa kunye neengxelo zezibalo zokushicilela, kubandakanywa ukuphambuka okuqhelekileyo kunye ne-coefficient of variation.
I-6, i-high degree of automation, i-design yesixhobo isebenzisa izixhobo eziphambili ekhaya nakwamanye amazwe, i-microcomputer yokuqonda ulwazi, ukusetyenzwa kwedatha kunye nokulawulwa kwesenzo, kunye nokusetha ngokuzenzekelayo, imemori yedatha, ukukhuselwa komthwalo ogqithisiweyo kunye neempawu zokuzixilonga.
I-7, i-Multi-function, uqwalaselo oluguquguqukayo.
Thumela umyalezo wakho kuthi:
