斜拉索动位移实时测定方法研究和系统开发
Method research and system development of real-time measurement for stay-cable dynamic displacement
摘要
Abstract
Based on the multi-targets dynamic displacement measurement technology, the real-time measurement method for the stay-cable was put forward. Based on LabVIEW, the program to use a single camera to measure the multi-targets dynamic displacement was developed. The dynamic displacement measurement system for the stay-cable was developed. The result of the indoor test was compared with that of the laser vibrometer. The validity of the method, the applicability of the multi-targets measuring and the accuracy of the result was proved. The effect of the measuring angel on the accuracy of the result was also discussed. The system was used to test the dynamic displacement of the stay-cable in Quanzhou Jinjiang Bridge. The reliability and the effectiveness of the method for the real bridge measuring were certified.关键词
