| 摘 要： | 基于静态测试手段及拉索的应力刚化效应和静力平衡原理，提出一种索力识别方法。因索力的获得只与施力点位移和施力大小有关，避免了常用索力测定方法测量精度受拉索边界条件及材料参数取值影响较大的缺点．为柔性拉索的索力识别提供了一种新的思路。

| Abstract: | This paper presents a cable tension identification method based on static testing measures as well as cable stress stiffening effect and principle of static equilibrium. The cable tension only depends on the displacement of load application point and the load force. The proposed method avoids the drawback of normal cable measuring methods where the measuring accuracy is greatly affected by cable boundary conditions or val- ues of material parameters. Therefore, it provides a new idea on cable tension identification of flexible cable. |
