摘　　要：阐述了频率法测试索力实验的开发理由,设计并制作了实验装置。由学生自主选定索的直径、长度、千斤顶施加荷载值等,通过测定频率代入公式得到相应的索力,从而与力传感器数值相比较,实验结果表明符合得很好,从教学效果来看,该项实验研究开阔了学生的学术视野,提高了动手能力和查阅文献的水平,收到了良好效果,为学生提供了一个自由探索的平台。This paper is concerned with the cable tension testing using frequency method, meanwhile, the corresponding equipments were designed and made. During the experiment, the parameters such as cable diameter, length, load value etc. That can be chosen freely, the experiment results show that the computed cable tension obtained by frequency value is well accord with the load value. Finally, this project can broaden the students＇ academic vision, at same time, improve the level of operational ability and literature review, providing one platform for exploring freely.
