Abstract:The specific application of stay cable frequency identification technology in road and bridge detection is expounded, and then the principle of vibration frequency method and the corresponding calculation formula are put forward. Through the test case, it is pointed out that the IBIS-FS system is used to carry out the multi-order frequency identification, and further to analyze the important factors affecting the force measurement of the stay cable, mainly including the boundary conditions of stay cable, setting of the bending strength, the accuracy of the spectrum analysis results, the shock absorber device, and the sags of stay cable. In the future, with the development of science and technology, the application of stay cable frequency identification technology can accurately identify the vibration frequency of the bridge and road.
