Finite Element Numerical Simulation and Experimental Verification of Frequency Characteristics of Wind-Induced Vibration of Catenary[J].

Wind-induced vibration of catenary is a typical disaster of railway power supply systems in windy areas. It is difficult for existing theoretical analyses of vibration characteristics and finite element software to accurately simulate field conditions, which makes it difficult to verify their calculation results with field measurement data, and is not conducive to improving the calculation accuracy of subsequent nonlinear models. Therefore, a small-scale catenary model was built. Firstly, a finite element numerical calculation program integrating the large-deformation geometric nonlinearity of catenary and the stretching-contracting stiffness nonlinearity of suspension string was written in MATLAB, and the vibration modes of the small-scale catenary model under lateral excitations of different frequencies were solved. Secondly, an experimental platform with adjustable lateral excitation frequency was built, and the vibration modes under horizontal airflows at various frequencies were measured by a laser displacement sensor. Finally, the vibration waveforms obtained by the two methods were comparatively studied. The calculation results indicate that in a certain frequency range, the vibration frequency of the model is the same as the lateral excitation frequency, and when the lateral excitation frequency is equal to the fundamental frequency of the model, the maximum horizontal displacement distance reaches the maximum. Under the lateral excitations of different frequencies, the trajectories of the measuring point are different: When the frequency is less than the fundamental frequency, the trajectory is mostly 8-shaped; when the frequency is greater than the fundamental frequency, it is mainly a flat oval; when the frequency is equal to the fundamental frequency, it is almost a horizontal straight line. By comparing the test results, it is revealed that the finite element numerical calculation method can accurately calculate the fundamental frequency of the model, as well as the response frequency, vibration mode, and variation trend of amplitude with frequency under excitation. However, there is a significant deviation between the calculated amplitude values and the test results. Therefore, the calculation and prediction of key amplitude values need to be corrected by combining with experiments.
