| 中文摘要: |
| 以某实验室独塔斜拉桥试验模型为研究对象，对斜拉桥模型试验的索力测试方法展开研究。开发了一种基于压力环传感器的索力测试系统，基于ANSYS分析平台，按照接触问题对该系统进行了仿真分析。在此基础上，在实验室模型桥上，采用测频法对该系统进行了对比验证。结果表明：该系统操作简单，性能可靠，测试精度较高，在不改变斜拉索刚度的情况下可以实现斜拉桥模型试验中斜拉索索力的实时、长期监测。 |
| 英文摘要: |
| Taking a single tower cable stayed bridge test model as an object, the method of cable force testing is researched. A cable tension test system based on pressure ring sensor is developed. The simulation of the system is done in ANSYS according to contact theory. On this basis, cable tensions of model bridge are measured by using this system and by frequence testing method. The result shows that the operation of this system is simple and the performance is stable and measuring results are reliable. Cable tension can be tested quickly and in real time by using this method without changing the stiffness of stay cables. |
