Lub tshuab ntsuas tensile, tseem hu ua lub tshuab ntsuas universal, yog siv dav hauv kev kuaj cov khoom siv tshuab. Nws lub luag haujlwm tseem ceeb yog ua cov tensile, compression, dabtsi yog khoov, thiab shear xeem ntawm ntau yam ntaub ntawv. Lub hauv paus ntsiab lus ntawm kev ua haujlwm tseem ceeb suav nrog kev siv lub zog tswj lossis hloov pauv mus rau ib qho qauv thiab ntsuas nws qhov deformation thiab pob txha tus yam ntxwv nyob rau hauv cov xwm txheej sib txawv kom tau txais cov ntaub ntawv kev ua haujlwm zoo.
Lub tshuab muaj lub tshuab thauj khoom, ntsuas qhov system, thiab tswj qhov system. Lub chaw thau khoom, feem ntau yog tsav los ntawm lub servo lub cev muaj zog lossis cov cuab yeej hydraulic, siv lub zog rau cov qauv los ntawm cov ntsia hlau, lub tog raj kheej hydraulic, lossis cov iav mechanisms. Cov qauv yog ruaj khov nyob rau hauv grips, thiab thaum lub load nce, cov khoom deforms. Kev thauj khoom ceev thiab quab yuam tuaj yeem raug kho raws li qhov xav tau ntawm kev sim.
Lub kaw lus ntsuas siv quab yuam sensors thiab txav sensors los saib xyuas cov qauv hauv lub sijhawm. Force sensors ntsuas lub tensile los yog compressive quab yuam siv rau cov qauv kom raug, thaum lub sij hawm hloov sensors sau cov elongation los yog compression ntawm cov qauv nyob rau hauv load. Cov ntaub ntawv no raug xa mus rau lub kaw lus tswj kev ua haujlwm, ua kom muaj kev ntxhov siab-strain curves thiab lwm yam tsis siv neeg kho tshuab.
Lub kaw lus tswj tau ua kom muaj kev ntsuam xyuas meej. Los ntawm lub khoos phis tawj lossis tus tswj hwm tshwj xeeb, cov qauv thauj khoom, tus nqi, thiab kev txiav tawm tuaj yeem teeb tsa. Cov ntaub ntawv sensor tau sau thiab tshuaj xyuas hauv lub sijhawm tiag tiag, kom ntseeg tau tias kev sim kev nyab xeeb thiab qhov tseeb tau tshwm sim. Niaj hnub nimno tensile xeem tshuab kuj tau nruab nrog kev nyab xeeb nta xws li kev tiv thaiv overload thiab tuav tuav mechanisms.
Thaum lub sij hawm ntsuas tensile, lub tshuab siv axial quab yuam rau cov qauv ntawm grips, sau tag nrho cov txheej txheem los ntawm elastic deformation, yielding, tawg. Hauv kev sim compression lossis dabtsi yog khoov, cov khoom siv thauj khoom siv qhov kev ntxhov siab tsim nyog rau cov khoom siv, saib xyuas nws cov load-cov kabmob muaj peev xwm thiab cov yam ntxwv tsis ua haujlwm.
Zuag qhia tag nrho, lub tshuab ntsuas tensile ntsuas cov khoom siv kho tshuab los ntawm kev siv lub zog tswj thiab ntsuas qhov deformations nrog precision. Ua ke nrog kev tswj hwm hauv computer thiab nrhiav tau cov ntaub ntawv, nws yog ib qho cuab yeej tseem ceeb hauv kev txhim kho cov khoom siv, kev ntsuam xyuas zoo, thiab kev siv engineering.
