Ka papiso ea metsamao ea lesela le angoang ka letsoho joalo ka ho hula, ho hatella, ho penta, ho duba le ho hohla, botenya ba lesela, ho kobeha, ho hatella, ho hohla le ho tsitsipana ho lekoa, 'me matšoao a mahlano a botenya, bonolo, ho satalla, boreleli le ho thatafala ho fumanoa ho hlahloba ka mokhoa o nepahetseng mokhoa o pharaletseng oa ho ikutloa ka letsoho oa lesela. E loketse lihlahisoa tse akaretsang tsa fiber flake: lesela la masela, lesela la masela la lapeng, lesela le sa loheng, khoele, bokahare ba koloi, letlalo, pampiri, jj.
Molao-motheo oa tlhahlobo ea masela:
E simulates subjective boikutlo tshebetso ya letsoho la motho ka lesela. Li-indenters tsohle tse sebelisoang ke libopeho tsa cylindrical tse etsisang menoana ea motho ka mela e metle, e sebelisetsoang ho etsisa menoana. Indenter e boetse e nka sebopeho sa e 'ngoe ka holimo le tse peli ka tlase ho etsisa mokhoa oa ho ama motho. Sistimi e lekanya li-index tse tsamaellanang ka tlhahlobo ea 'mele ea thepa, joalo ka khatello, ho kobeha, likhohlano le tsitsipano,' me e fumana botenya ba compression ea holim'a metsi, bonolo SF, stiffness ST, smoothness SM le tightness LT, ebe e lekola setaele se felletseng. lesela.
1. Tekanyo ea botenya, botenya ba lesela le hatelitsoeng ke bokaholimo bo kobehileng.
2. Sethaleng sa pele, bokaholimo bo hatelloa ho fumana modulus ea compression le deformation ea compression, e hlalosoang e le SF e bonolo.
3. Mokhahlelong oa bobeli, teko ea ho khumama e fumana boholo ba ho khumama, ho khumama modulus, mosebetsi oa ho khumama, joalo-joalo, e hlalosoang e le ho satalla ST.
4. Mokhahlelong oa boraro, karolelano ea matla a khohlano, coefficient ea likhohlano, mosebetsi oa likhohlano, joalo-joalo, le sliding degree SM li fumanoa ka tlhahlobo ea likhohlano.
5. Sethaleng sa ⅳ, modulus ea tsitsipano, mosebetsi o tsitsitseng, joalo-joalo o fumanoa ka teko ea boima, e hlalosoang e le ho tiea LT. Tlhahlobo e felletseng ea liphetho tsa liteko: setaele se felletseng CH=A*SF+B*ST+C*SM+D*LT sistimi e tla fumana SF, ST, SM, LT index ka 'ngoe e arotsoe ka mekhahlelo e le' ngoe, tse peli, tse tharo, tse 'ne, tse hlano. . Setaele se felletseng ke kakaretso ea litekanyo tsa bonolo, ho satalla, boreleli le ho tiea, 'me li-coefficients A, B, C le D li ikemiselitse ka botlalo ho latela ts'ebeliso, mofuta le thepa ea thepa.
Likarolo tsa Sehlahisoa:
1. Papiso ea setšoantšo ea matsoho a motho
2. Ho lekanya matšoao ho tla etsa hore liphetho li be tsa saense haholoanyane
3, ts'ebetso e bonolo, mochini o le mong tekanyo e le 'ngoe ea matšoao a mangata
4. Motsoako oa mohlala oa mechine le teko ea 'mele
5, lisebelisoa li na le litšenyehelo tse ngata, sesebelisoa sa mantlha se nepahetseng hantle, taolo e nepahetseng, ts'ebetso e tsitsitseng haholoanyane.
