摘要
高速列车通过桥梁时将会产生列车与桥梁相互耦合的振动。多跨简支梁形式的桥梁在高速铁路线中占相当大的比重。本文应用车桥耦合振动理论 ,通过大量计算机仿真计算 ,讨论和分析了跨径布置和共振的相互关系。
The coupled vibration between bridge and vehicle would be pronounced when high-speed vehicles pass through bridge.Among the bridges in high railway multi-span simply supported girders take a great percentage.In the paper,the relationship between span arrangement and bridge resonance is analyzed by the dynamic response calculation.
