Lub ntsiab lus ntawm cov khoom siv kho tshuab thiab lawv suav nrog
- Kev txhais ntawm cov khoom siv kho tshuab
Mechanical zog hais txog yuav ua li cas cov khoom ua tau raws li cov neeg kho tshuab loading. Mechanical loads muaj xws li static loads thiab dynamic loads. Kev ua tau zoo ntawm cov ntaub ntawv hauv qab no yog cov khoom siv kho tshuab. Cov cuab yeej siv tshuab yog ib qho tseem ceeb ntsuas los ntsuas seb cov khoom puas haum rau ib puag ncig siv tshwj xeeb. Nws tseem yog ib feem tseem ceeb ntawm kev tshawb fawb hauv cov ntaub ntawv science thiab engineering.
- Tej yam xws li mechanical zog
1. Lub zog: Lub zog yog lub peev xwm ntawm cov khoom siv los tiv thaiv deformation thiab kev puas tsuaj nyob rau hauv kev ntxhov siab. Nws feem ntau yog kuaj los ntawm kev nro, compression, thiab lwm yam. Lub zog ntsuas muaj xws li lub zog tawm los, lub zog tensile, compressive zog, thiab lwm yam.
2. Toughness: Toughness yog hais txog cov khoom muaj peev xwm tswj tau ib qho kev deformation nyob rau hauv lub zog quab yuam, uas yog lub peev xwm los tiv thaiv puas. Feem ntau siv toughness ntsuas suav nrog tawg toughness, cuam tshuam toughness, thiab lwm yam.
3. Hardness: Hardness yog lub peev xwm ntawm ib yam khoom los tiv thaiv khawb los yog indentations. Ntsuas hardness tuaj yeem cuam tshuam qhov hnav tsis kam ntawm cov khoom. Feem ntau siv txoj hauv kev rau kev sim hardness xws li Brinell hardness, Rockwell hardness, Vickers hardness, thiab lwm yam.
4. Kev ua haujlwm qaug zog: Kev ua haujlwm qaug zog yog hais txog qhov ua tau zoo ntawm cov khoom siv nyob rau hauv kev sib hloov kev ntxhov siab, uas yog, seb cov khoom puas tuaj yeem ua rau qaug zog tawg lossis kev puas tsuaj hauv lub voj voog.
5. Kev cuam tshuam kev ua haujlwm: Kev cuam tshuam kev ua haujlwm yog hais txog cov khoom muaj peev xwm tiv thaiv kev puas tsuaj nyob rau hauv qhov cuam tshuam tam sim ntawd. Kev cuam tshuam lub zog thiab toughness yog cov cim tseem ceeb uas qhia txog cov khoom siv tiv thaiv kev puas tsuaj.
- Kev siv cov khoom siv kho tshuab
Cov khoom siv tshuab yog cov cim tseem ceeb hauv kev xaiv cov khoom siv, tsim thiab siv. Mechanical zog ntawm cov khoom sib txawv sib txawv heev. Los ntawm kev kawm thiab ntsuas cov khoom siv kho tshuab, peb tuaj yeem nkag siab zoo dua cov yam ntxwv, qhov zoo thiab qhov tsis zoo ntawm cov ntaub ntawv, thiab muab lub hauv paus rau kev xaiv thiab siv cov khoom siv. cov ntaub ntawv kev sib deev.
- Cov ntsiab lus
Cov khoom siv kho tshuab yog kev ua haujlwm ntawm cov khoom siv hauv cov khoom siv thauj khoom, suav nrog lub zog, toughness, hardness, qaug zog kev ua tau zoo, cuam tshuam kev ua haujlwm thiab lwm yam. Cov cuab yeej cuab yeej ntsuas no tuaj yeem cuam tshuam txog kev ua haujlwm thiab kev siv ntawm cov ntaub ntawv thiab muab cov hauv paus thiab siv rau kev xaiv thiab siv cov khoom siv.
