摘要
针对目前斜拉桥索力测定中存在的问题 ,提出采用“三点弯曲法”原理测定拉索索力 ,并由此设计出接触式索力测定传感器。文中介绍了传感器的测试方法及原理 ,阐述了拉索索力测定过程及信号处理方法。研究结果表明采用该测试方法可实现斜拉桥拉索索力的精确。
A high precision cable tension sensor is developed by means of three point loading flexure. The determining method and principle for cable tension sensor are analyzed. The determining process and method of data processing are introduced. The research results demonstrate that the determining method has many advantages such as simple and convenient, high precision and so on.
