The Physics of Contact: How Groove Radius and Hardness Dictate Lateral Rope Compression

Forensic Engineering Visual: Kev tshuaj xyuas ntawm cov ncauj lus tshwj xeeb.

Ib txoj hlua hlau yog lub tshuab ua haujlwm nyob rau hauv lwm lub tshuab-txoj hlua thiab nruas. Lub geometry ntawm sheave zawj yog thawj sab nraud determinant ntawm txoj hlua lub neej qaug zog. Thaum cov zawj profile tsis phim txoj hlua lub nominal txoj kab uas hla, ib tug series ntawm complex lateral rog -paub li "pinching"- tsub kom lub degradation ntawm cov strands.

 

Lub Radius ntawm Failure:

Ib qho kev noj qab haus huv sheave zawj yuav tsum feem ntau muaj lub vojvoog ntawm 0.525 txog 0.550 npaug ntawm txoj hlua nominal txoj kab uas hla. Yog hais tias qhov zawj yog nruj heev, nws "pinches" txoj hlua, tiv thaiv tus neeg xaim los ntawm zawv zawg rau ib leeg thaum khoov. Qhov no xauv cov hlua sab hauv thiab ua rau qaug zog nrawm nrawm ntawm "inter-strand contact point." Hloov pauv, yog tias qhov zawj dav dhau, txoj hlua flattens nyob rau hauv load, ua rau cov qauv deformation lossis "birdcaging."

 

Lub Hardness Differential:

Qhov zoo tshaj plaws, cov hlua khi yuav tsum yog me ntsis softer dua li cov hlua hlau hlua kom tiv thaiv txoj hlua "txiav" rau hauv lub tshuab. Txawm li cas los xij, hauv qhov hnyav - lub luag haujlwm chaw nres nkoj cranes, peb feem ntau pom cov sheave hardened grooves. Nyob rau hauv cov ntaub ntawv no, txoj hlua nto ua lub sacrificial khoom. Ntawm SOLITE, peb muab sheave-kev soj ntsuam kev sib raug zoo rau peb cov neeg siv khoom, siv cov ntsuas ntsuas kom ntseeg tau tias cov khoom siv sib txuas ntawm cov hlau thiab cov sheave yog ib qho kev sib koom tes zoo ntawm geometry thiab physics.
