［摘要］以Galfan拉索為研究對象，采用ABAQUS軟件對6種規(guī)格鋼絞線拉索在軸向力作用下的索截面徑向位移進(jìn)行了數(shù)值模擬分析。分析結(jié)果表明，各規(guī)格Galfan拉索軸力在(5%～70%)的最小破斷力Fu范圍內(nèi)時(shí)，拉索軸力與外層鋼絲徑向位移有著明顯的線性關(guān)系，并通過數(shù)值模擬分析結(jié)果,擬合得到線彈性階段內(nèi)各規(guī)格Galfan拉索最外層鋼絲徑向位移的計(jì)算公式，可為拉索結(jié)構(gòu)的索夾優(yōu)化設(shè)計(jì)提供依據(jù)。

Abstract:Taking Galfan cables as research objects, ABAQUS finite element software was used to conduct numerical simulation analysis on the radial displacement of the cable sections of 6 types of steel stranded cables under the axial force. The analysis results show that: when the axial force of the steel stranded cables of various specifications is in the range of (5%～70%) of minimum breaking force Fu, the axial force of the cables and the radial displacement of the outer steel wire have a clear linear relationship. Through the numerical simulation results, the calculation formula of the radial displacement of the outermost steel wire of Galfan cable of various specifications in linear elastic stage was fitted and obtained, providing the basis for the optimal design of cable clamp of the cable structure.
Keywords:Galfan cable; steel wire; cable section; radial displacement
