Xa uthelekisa izibonelelo, buza ukuba loluphi uluhlu olusebenzisekayo — hayi ukuba loluphi ubuninzi.
2. Ulawulo lwesantya lugqiba ekubeni idatha yakho iyafana na
Iipolymers, iifilimu kunye nezincamathelisi zi-viscoelastic: amandla azo alinganiswayo axhomekeke ekubeni utsala ngokukhawuleza kangakanani. Tshintsha isantya se-crosshead kwaye amandla okuxobula, ukunwebeka kunye ne-modulus zonke zihamba, ngaphandle kokutshintsha kwezinto.
Yingakho imigangatho ichaza isantya soxinzelelo esingaguqukiyo endaweni yesantya esiqhelekileyo, kwaye kutheni iumatshini wokuvavanya ukuxinana kwe-servo osebenzisa ikhompyuthalusisiseko sayo nayiphi na ilabhoratri ekhupha idatha efanayo. I-drive yesantya esimiselweyo okanye yesantya esinye inokuvelisa inombolo; ayinakuvelisa enokukhuselwa.
Ulawulo lweServo lukwavula iindlela ze-multi-loop — uxinzelelo oluqhubekayo, uxinzelelo oluqhubekayo, ukukrazuka kunye nokuphumla — izinto ezingenakwenzeka kumatshini owaziyo ukuhamba ngesantya esinye kuphela. Ukuba uluhlu lwemveliso yakho luquka ii-gaskets, ii-seals okanye ii-geotextiles, oku kuyimfuneko kunokuba kube lukhetho.
3. Iigrips zigqiba ngento onokuyivavanya
Isakhelo siqhelekileyo; izinto ezisetyenziswayo kunye neegrips zezona zenza umatshini ufanelekele ilaphu, ifilimu, iteyiphu, irabha okanye iphepha. Iilabhoratri ezimbini ezineematshini ezifanayo kunye neeseti ezahlukeneyo zokubamba ziya kuxela iziphumo ezahlukeneyo kwisixhobo esifanayo.
Ukusilela okuqhelekileyo kusemhlathini, kungekhona kwisampuli. Ii-wedge grips zigxininisa uxinzelelo kwaye zibangela ukuqhekeka kwangaphambi kwexesha kufutshane nomhlathi kwifilimu encinci; ii-pneumatic grips ezinoxinzelelo olulawulwayo zisasaza ngokulinganayo; i-foam okanye i-elastomer zifuna ukubamba okunganqumkiyo. Uvavanyo lwe-textile strip lufuna imihlathi ebanzi ngokwaneleyo ukubamba ububanzi besampuli yonke ngaphandle kokutyibilika.
Kuvavanyo lwexolo, ijiyometri ibaluleke kakhulu njengokuba amandla: ixolo le-90° kunye ne-180° ziimvavanyo ezahlukeneyo, kwaye isixhobo - kungekhona umatshini - simisela i-engile. Isicatshulwa esidwelisa umatshini ngaphandle kokubhala iseti yokubamba sisicatshulwa sesiqingatha senkqubo.
4. Izinga lokuvavanya kunye noko isoftware inokuthumela ngaphandle
Amandla e-peak yinqaku elinye. I-Modulus, ukuziphatha kwe-yield kunye nokuma kwe-failure curve zonke zixhomekeke ekubeni idatha ithathwe ngobuninzi kangakanani, kwaye nokuba isoftware ingakwazi na ukubala amaxabiso afunyenweyo afunwa ngumgangatho.
Ukuhlolwa okubini okusebenzayo. Okokuqala, ingaba isoftware ibala iziphumo ezifunyenweyo ngokwendalo na — ukunwebeka kuxinzelelo oluthile, i-secant modulus, amandla okuphuka — okanye ingaba umqhubi kulindeleke ukuba aqhubeke nenkqubo kwispredishithi, apho ukulandeleka kunyamalala khona ngokuzolileyo. Okwesibini, ingaba idatha eluhlaza ingathunyelwa ngaphandle nge-curve ingasebenzi, kuba ingxelo ebonisa isigwebo kuphela kunzima ukuyikhusela xa umthengi ephikisana neqela.
5. Ukuqina kwesakhelo kunye nokulungelelaniswa
Aumatshini wovavanyo oluqhelekileyoIsakhelo esijika phantsi komthwalo sizilinganisa kunye nesampuli. Kwiisampuli eziqinileyo impazamo incinci; kwifilimu enobude obuphezulu kunye neefayibha ezincinci, ukuhambelana kwentloko kunye nokulungelelaniswa okungalunganga kwekholamu kunokutshintsha iziphumo ngaphezu komahluko ozama ukuwufumana phakathi kweebhetshi.
Ulungelelwaniso alubonakali kwiphepha leenkcukacha, yiyo loo nto kufanelekile ukucela ingxelo yokuqinisekisa endaweni yokuzoba ifreyimu. Ukulawula umgangatho rhoqo, imfuneko incinci; kwilabhoratri ekhupha idatha evunyiweyo,I-ISO 7500-1Ukuqinisekiswa kweklasi yesibonakaliso samandla, kunye nokujonga ukuthamba kunye nokulungelelaniswa, bubungqina obuza kujonga umntu wesithathu.
