［摘要］介紹了利用彈性工程磁學進行索張力測試的基本原理，設計了基于彈性工程磁學原理測試索張力的儀器。進行了索張力測試的試驗研究，并對試驗結(jié)果進行了整理分析。試驗結(jié)果表明，不同應力下磁導率有明顯變化，說明通過測試不同拉力下的拉索材料的磁導率反應可以測量拉索所受拉力的大小。

Abstract:The basic theory of the elasto-magnetic method and the corresponding principle for measurement of cable tensions are introduced. Based on this theory, measurement instruments are designed. An experimental investigation on the measurement of cable tensions is conducted. The purpose of experimental investigation is to test the applicability and effect of this kind of instrument. Through the investigation, some testing curves are gained, and the applicability and effect of this kind of instrument are proved.
Keywords:cable tension; elasto-magnetic method; measurementtheory and principle; experiment
