Abstract:Abstract: Based on super-long crossing-channel cable-stayed bridge Scheme of over Qiongzhou strait, the refined numerical simulation model of whole vehicle and whole bridge system for coupled vibration analysis is set up. The dynamic analysis model of cable-stayed bridge Scheme of crossing-channel project over Qiongzhou strait is established by use of space bar-shell hybrid finite element method, and the natural vibration properties of the bridge are analyzed. The refined three-dimensional space vehicle model is set up by multi-system dynamics software SIMPACK, and the multiple non-linear properties are considered. The space vibration responses are calculated by co-simulation based on multi-body system dynamics and finite element method when only a train passes and when two trains pass the long span cable-stayed bridge with the opposite direction at different speeds in order to test if the bridge has the sufficient lateral or vertical rigidity and the operation stability is fine. The calculation results show: The operation safety can be guaranteed, and comfort index is “good”. The bridge has sufficient rigidity, and vibration is in good condition. The results provide a reference for design.
