摘　　要：根据车—桥耦合振动理论 ,提出了一套抑制列车通过时铁路钢板梁桥振动响应的振动控制方案 ,并以一座实桥作为研究对象 ,对控制前、后列车以不同速度通过时桥梁结构的振动响应进行了研究 。Based on the coupling theory of interaction of vehicle-bridge system, a strengthening method of controlling the vibration response of steel plate bridge due to the vehicle excitation is presented. Taking an actual bridge as an example, the vibration response of bridge fore-and-aft control under different speed is studied. The calculated results prove that the method of this paper is effective.

关 键 词：耦合振动 振动控制 振动响应 铁路钢板梁桥
