摘 要:
本文介绍了弹性工程磁学的基本理论以及利用弹性工程磁学进行索张力测试的基本原理,设计了基于弹性工程磁学原理测试索张力的仪器并对该仪器做了介绍,进行了索张力测试的试验研究,介绍了试验内容并对试验结果进行了整理分析。试验结果表明不同应力下,磁导率有明显变化,且可测,这就证明了通过测试不同拉力下的拉索材料的磁导率反映可以测量拉索所受拉力的大小。[著者文摘]

Abstract:
The measurement of the tensile cable is an important issue in the field of civil engineering. In this paper, the basic theory of elasto-magnetic method and the corresponding measurement principle of cable tension are introduced. Then, based on this theory, a measurement instrument was designed. Basic principle of the instrument is expatiated. Finally, an experimental investigation on the measurement of cable tension was conducted. The purpose of experimental investigation is to test the applicability and effect of this kind instrument. Through the investigation, some test curves were obtained, which prove the applicability and effect of this kind instrument.[著者文摘]
Key words:
