| 中文摘要: |
| 考虑桥面不平顺的随机激励及阻尼作用，把桥梁和车辆视为一个相互作用系统，利用达朗贝尔原理和欧拉-伯努利梁假设，对不同公路桥车桥耦合相互作用模型的动力特性进行分析.较真实的反映了桥梁结构在车辆荷载作用下的动态受力和变形本质，对桥梁的动力设计、振动控制以及动力性能评估有一定的实际意义. |
| 英文摘要: |
| Considering random incentive of deck irregularity and damping action and regarding vehicle and bridge as an interaction system, this paper analyzes the dynamic characteristics of the Vehicle-Bridge Coupled Vibration under different models by the D’Alembert’s principle and the hypothesis of Euler-Bernoulli beam. The studies here comparatively truly reveal the dynamic behavior and deformation of the bridge structure under vehicle load. It would be of practical value in dynamic design, vibrating control and capability evaluation. |
