摘要：

The flow-induced vibration of the outer windshield of high-speed train intensifies as the train's speed increases, impacting stability and safety during operation. The vibration characteristics of outer windshields are crucial for optimizing higher-speed train design. In this paper, proper orthogonal decomposition (POD) in conjunction with the pseudo excitation method (PEM) is applied for flow-induced vibration analysis of windshield. The dynamic model of the windshield is established by mode superposition method to reduce the degrees of freedom of the windshield structure. By utilizing the pr...
