摘要: 研究了“三点弯曲式”钢索张力测定器的工作原理及其输出信号P、δ与张力T的关系.阐明钢索抗弯刚度不可忽略,它随张力T而改变.从理论上导出了张力测定器标定装置应有的长度Abstract: This paper studies the theory of “three point bending”wirerope tension meter and the relationship between the tension T and the output values P,δ. It is shown that the bending stiffness EI of wirerope can not be neglected and it varies with tension T.A reasonable length of the calibrater for wire rope tension meter is also obtained.
