Tsis zoo compression nyob rau hauv lublub zog clampfeem ntau ua rau cov strands overheat thiab tawg.Muaj ib qho kev sib txawv

nruab nrab ntawm conductors thiab covlub zog clampyog hais tias lub lim clamp yog compressed tsis zoo.Cov hmoov tshauv, oxide, corrosion

thiab abrasion yuav sib sau ua ke thiab teev nyob rau hauv qhov sib txawv, tsim scale txheej ntawm siab resistivity.Raws li lub sij hawm raug

nce, cov khaubncaws sab nraud povtseg nthuav thiab thicken, uas ua rau lub phem ntawm conductive zogntawm tam sim no thiab

Thaum tshav kub kub, thiab ua rau qhov txawv txav ntawm qhov siab, qhov degradation ntawm microstructure thiab cov khoomthiab

strands tawg thaum kawg.Nyob rau hauv kev txiav txim siab ntawm qhov zoo ntawm cov strands tawg phenomenon thiab los ntawm FEM, tsis yog-

uniform kub teb cuam tshuam los ntawm scale txheej nyob rau hauv lub clamp tau soj ntsuam thiab cov kev sib raug zoo

nruab nrab ntawm cov nplai txheej, qhov siab tshaj qhov kub thiab qhov tam sim no tau txais.Cov txiaj ntsig ntawm kev sim cov ntaub ntawv qhia

hais tias cov strands sib txawv ntawm ib leeg nyob rau hauv roundness ntawm shear daim di ncauj.Kev yaig loj yog pom ntawm qhov chaw ntawm sab nrauv

Al (aluminium) strands txuas rau lub clamp, thaum yuav luag tsis muaj kev yaig ntawm qhov chaw txuas rau sab hauv

Al strands.Erosion me ntsis hauv Al strands nto txuas mus rau txheej txheej yog qhov tob tshaj plaws, thiab txhua qhov kev yaig yog qhov loj.

thiab qee qhov uas tau tsim los ua plaques.Qhov sib cuam tshuam deterioration ntawm nplai thiab kub ua rau lub

Al strands txuas mus rau txheej txheej ua tsis tiav thiab tom qab ntawd ua rau tawg-kub domino nyhuv ntawm lwm cov strands.Cov

longitudinal fibrous microstructure ntawm steel strands ploj thaum kub nce.Plasticity ntawm strands

nce tom qab rov qab thiab recrystallization.Lub degradation sai ntawm mechanics zog ua rau poob
