考虑风浪相关性影响的高速列车-轨道-跨海斜拉桥时变系统动力响应分析
Dynamic response analysis of time-varying system of high-speed train-track-sea-crossing cable-stayed bridge under the action of related wind and wave
摘要
Abstract
In order to study the effect of wave parameters and the correlation between wind and wave on the train-track-bridge coupling vibration analysis of a sea-crossing high-speed railway bridge,the Gumbel joint probability model was adopted for the correlation of wind and wave based on synchronous observation data of winds and waves.The time histories of wind and wave were simulated by the spectral representation method.As an example in ANSYS and SIMPACK co-simulation,the analysis model of high-speed train and sea-crossing cable-stayed bridge was established.The vibration of high-speed train passing through the sea-crossing cable-stayed bridge under the action of single wave,single wind and related wind and wave were carried out respectively.The effects of significant wave height,water depth and wind speed on the dynamic responses of train and bridge were studied.The results of train-bridge dynamic responses show that wave mainly affects the lateral responses of train and bridge,and has a relatively small impact on the vertical responses.The increase of significant wave height and water depth will both increase the dynamic responses of train and bridge,and the amplification will both be higher.When the effective wave height is large,it is the main factor affecting the dynamic response of train and bridge.When the effective wave height is low,the water depth and the effective wave height have the same impact on the dynamic response.The frequency components in the lateral displacement of the midspan of the main beam under wave action mainly includes the wave frequency and the first-order transverse bending frequency of main beam,and the increase of effective wave height leads to an increase in the first-order transverse bending frequency of main beam.Compared with the wind action,the dynamic responses of train and bridge significantly increases after considering the correlation between wind and wave.The correlation between wind and wave should be considered when determining the wind speed and wave height for dynamic response analysis.关键词
