摘　　要：为了降低车身振动给城轨车辆复合结构产生的危害,利用阻尼力调节技术优化城轨车辆复合结构车身减振控制系统;在考虑城轨车辆复合组成结构和工作方式的情况下,构建了城轨车辆复合结构模型;在该模型下,结合城轨车辆的运行环境,模拟城轨车身在不同场景下的振动过程;利用安装在车身传感器,获取城轨车辆的实时运行数据,提取城轨车身振动特征,计算车身阻尼力调节量的理论值;采用可调阻尼器作为执行元件,执行可调阻尼力,在系统减振控制器的支持下,实现城轨车辆复合结构车身减振控制功能;通过系统测试得出结论:应用基于阻尼力调节的城轨车辆复合结构车身减振控制系统后,车身振动频率和振动幅值得到明显降低。In order to reduce the harm caused by body vibration to the composite structure of urban rail vehicle,a damping force adjustment technology is used to optimize the body vibration reduction control system of the composite structure of urban rail vehicle.In the case of considering the composite structure and working mode of urban rail vehicle,a composite structure model of urban rail vehicle is proposed.In this model,combined with the operating environment of the urban rail vehicle,the vibration process of the urban rail vehicle in different scenarios is simulated.The sensors that installed in vehicle are used to obtain the real-time running data of the urban rail vehicle,acquires the vibration characteristics of the urban rail body,and the theoretical value of the adjustment amount of the body damping force is calculated.The adjustable damper is used as the executive element to perform the task of adjusting the damping force.With the support of the system vibration reduction controller,the vibration reduction control function of the composite structure body of the urban rail vehicle is realized.Through the system test,it is concluded that,after the damping force adjustment-based composite structure body vibration control system is applied for the urban rail vehicle,the vibration frequency and vibration amplitude of the vehicle body are significantly reduced.
