摘　　要：国民经济的快速发展带动了交通运输业的迅速成长,加大了桥梁维修养护的强度,应社会需求,在不中断交通条件下,研究通过控制振动的方式来实施桥梁的维修及养护工作成为必要。以已有的加固技术为基础,从改变本身的动力系数出发,即安装阻尼器,并对阻尼器的型号选择及布置形式进行优化达到减振目的。本文整理分析了车桥动力响应及阻尼器的控制应用,阐述了桥梁的振动特性,传统阻尼器的应用效果及不足,为后续采用粘滞阻尼器或TMD的减振措施指明了方向。The rapid development of the national economy has led to the rapid growth of the transportation industry,increasing the strength of bridge maintenance.In response to social needs,it is necessary to study the way to control vibration to implement bridge maintenance and maintenance under the condition of uninterrupted traffic.Based on the existing reinforcement technology,starting from the change of its dynamic coefficient,namely the installation of dampers,and the type selection and layout of dampers are optimized to achieve the purpose of vibration reduction.This paper analyzes the dynamic response of vehicle and bridge and the control application of damper,expounds the vibration characteristics of the bridge,the application effect and deficiency of traditional damper,and points out the direction for the subsequent damping measures of viscous damper or TMD.
